INDUSTRY INSIGHT

A new perspective on water: Cunliffe Report calls for a “Great Stink” moment

By Paul Horton - CEO Future Water Association

The final report from the Independent Water Commission, chaired by Sir Jon Cunliffe, is being widely hailed as the most ambitious attempt to reform the UK water sector since privatisation. With 88 detailed recommendations, the report calls for a fundamental reset to how water services are governed, regulated, and delivered.

Framed by Cunliffe himself as a modern-day “Great Stink” moment, the report sets out to address the environmental, public health, and structural challenges facing the sector with urgency and vision.

Much like the infamous 1858 pollution crisis on the Thames that spurred Victorian engineering reforms, today’s water issues, pollution, public dissatisfaction, and fragmented oversight have created a crisis of confidence. In Cunliffe’s view, this moment demands equally bold and systemic action.

At the heart of the report are five transformational proposals, which Sir Jon reinforced in his speech at the launch:

A single “super-regulator”

Perhaps the most high-profile recommendation is the abolition of Ofwat, with its economic regulation role merged with the water-related functions of the Environment Agency, Drinking Water Inspectorate, and Natural England. This new integrated body would offer a “wholefirm” view of water companies, moving away from fragmented oversight and towards joined-up accountability. The Government has already indicated support for this change, suggesting rapid progress may follow.

A truly strategic direction

The report criticises government for failing to provide clear long-term planning for the sector. To correct this, it recommends a National Water Strategy supported by independent regional planning bodies in England and a single national planner in Wales. These authorities would be empowered to align investments with climate, environmental, and customer priorities.

Improved governance and accountability

To rebuild public trust, the report recommends that regulatory powers be expanded to block changes in water company ownership that are not in the public interest. New

“public benefit” duties would be inserted into company licences, and a more rigorous framework introduced for senior executive accountability.

Strengthened

consumer and environmental protection

A series of recommendations target pollution, fairness, and water efficiency. These include accelerating the rollout of smart metering, strengthening sludge and drinking water standards, promoting water reuse, and creating a national social tariff for low-income households. The Consumer Council for Water would be upgraded to an ombudsman service to enhance complaint resolution.

A modern infrastructure delivery model

The Commission recommends creating a Water Infrastructure Company within the new National Infrastructure and Skills Transformation Authority (NISTA). This body would oversee long-term infrastructure delivery, standardise procurement, and help bring innovation to scale. It would play a coordinating role across complex, multi-stakeholder water investment projects.

The report has sparked a wave of reflection across the sector. It recognises the dedication of frontline workers but makes clear that the current governance model is not fit for purpose. It also presents a call to action: to redesign systems around resilience, sustainability, and trust.

Paul Horton, CEO Future Water Association

Organisations such as Future Water, which represents a crosssection of the supply chain, from utilities and equipment providers to consultants, technologists, and academics, have found strong alignment between the Commission’s recommendations and their own policy positions.

Future Water’s submissions to the Call for Evidence and Interim Report repeatedly called for:

• Integrated regulation to streamline accountability.

• Clearer long-term investment signals.

• A joined-up approach to standards and innovation.

• A proactive strategy to address digital resilience and cybersecurity.

• The introduction of a national water skills plan.

The Commission’s final proposals reflect many of these themes. In particular, Future Water’s work on standards mapping, which models the relationships between utilities, regulators, and supply chain actors, could serve as a practical foundation for shaping the structure of the new single regulator.

While the report has been widely praised for its scope and clarity, it has not been without criticism. Sir Jon Cunliffe himself acknowledged that implementation would take time, requiring primary legislation and sector-wide consultation. He estimated that establishing the new regulatory model could take two years, referencing previous largescale regulatory mergers such as the creation of Ofcom.

There are also voices arguing that the reforms do not go far enough. Various campaign groups have criticised the

report for staying within the boundaries of the current privatised model. They argue that the report fails to address what they see as the root cause of underperformance: a system that places profit above public interest. While the Commission did consider stronger public benefit duties and tighter governance, it was not permitted to examine public ownership as a structural alternative, a limitation some view as a missed opportunity.

Despite the complexities, the report presents significant opportunities, particularly for the supply chain. The call for smart metering, digitalisation, and standardisation of delivery models offers a clearer entry point for suppliers and innovators. The proposed Water Infrastructure Company could help derisk procurement and drive consistency across regions.

Future Water’s working groups, including those focused on metering, digital resilience, emerging talent, and innovation, are well positioned to support delivery. Their experience developing maturity

frameworks, advising on data interoperability, and building sector-wide collaboration will be invaluable as the sector transitions into this new model.

Framing this as the water sector’s “Great Stink” moment is no empty metaphor. Just as the 1858 crisis catalysed the creation of London’s sewers, today’s challenges, pollution, mistrust, and fragmentation, are prompting a longoverdue systemic shift.

As Sir Jon Cunliffe put it, “there is no single, simple change” that will fix the sector, but the breadth and depth of the Commission’s recommendations offer a genuine opportunity to rebuild the system on firmer, more transparent foundations.

The next step lies with the Government, which is expected to respond later this year. The sector, meanwhile, must prepare for transformational change. Future Waters voice has clearly resonated throughout the Commission’s process and will be central in turning vision into reality.

RSM Open Day 2025

Advancing pipeline rehabilitation solutions

Innovation, collaboration, and new product launches mark a successful industry showcase

RSM Lining Supplies hosted its sixth biennial Open Day on 4th September 2025, welcoming customers, partners, and exhibitors to its headquarters despite challenging weather conditions. The event once again confirmed its status as a key fixture in the sewer rehabilitation industry calendar.

The Open Day combined technical presentations, live demonstrations, and new product launches with valuable opportunities for networking and hospitality. Beyond the serious business of trenchless technology, guests also enjoyed RSM’s trademark entertainment, including evening performances from BBC Radio One’s James Cusack and the legendary Judge Jules. This blend of industry insight and customer appreciation reflects the company’s ethos: combining technical excellence with strong, long-term partnerships.

Milestones since 2023

The event also served as a platform to reflect on RSM’s achievements since the last Open Day in 2023. In just two years, the company has processed more than 80 kilometres of liner through its impregnation service, manufactured and dispatched over 93,500 Pipe Aid Kits, and supplied more than 42 kilometres of UV liner. Training has also been a major focus, with 370 engineers completing RSM’s certified course.

In the past 12 months alone, the business has provided products and services to 736 customers in 27 countries, a measure of its growth and reputation as a global solutions provider in pipeline rehabilitation.

Product launches and technical innovations

Visitors to the 2025 Open Day had the opportunity to see several major new products first-hand. Among them was an enhanced UV LED curing cable for the Sewertronics SpeedyLight+ system, designed to reduce kinking and improve usability, particularly in demanding site conditions.

The launch of the Gecko E Lateral and Gecko E Power Cutters also attracted attention. Compact and electrically powered, these cutters are tailored to the increasing demand for low-emission, batterycapable equipment in urban projects where access, noise, and environmental restrictions are critical.

Finally, RSM introduced its WRc-approved Manhole Spray Lining System, which applies the GeoKrete Geopolymer to create a long-lasting, corrosionresistant barrier for manhole rehabilitation. Together, these launches underscored RSM’s commitment to delivering complete, integrated systems that address the real challenges faced by contractors. >

Live rehabilitation demonstration

One of the highlights of the day was a comprehensive live rehabilitation sequence, showing how RSM’s technologies perform when used in combination. The process began with the inversion of a liner preimpregnated with CP655 Class 1 Epoxy Resin, installed using a KrasoTech Sluice 300. Curing was then carried out with the KrasoTherm Hybrid Boiler, with progress monitored in real time via the VeriCure system.

Attendees watched as the Gecko E Lateral Cutter reinstated laterals with speed and precision, before connections were sealed using a Top Hat System to ensure watertight joints. The sequence continued with UV LED curing of the lateral liner using the upgraded

Sewertronics SpeedyLight+, and concluded with manhole rehabilitation, where the Spray Lining System applied GeoKrete Geopolymer for durable, long-term protection.

This step-by-step demonstration highlighted the efficiency, reliability, and environmental benefits of RSM’s integrated solutions, leaving visitors with a clear impression of how the systems can perform together on site.

Collaboration across the supply chain

The Open Day also celebrated collaboration across the trenchless supply chain. RSM partners — including Applied Felts, BKP Berolina, Dancutter, KrasoTech, Picote Solutions, Sewertronics, UKSTT, Vortex, VP Polymers, Westrade

Group, and WRc Group — supported the event, sharing insights and innovations.

This collective presence underlined the importance of partnerships in advancing trenchless technologies, from developing new materials and systems to ensuring contractors have the training and technical support they need on site.

Looking ahead

Managing Director Richard Davis reflected on the event’s success:

“The Open Day was a true reflection of the teamwork, innovation, and commitment that drives RSM. I could not be prouder of how far we’ve come, and I want to thank our customers for their loyalty and support. Without them, none of this would be possible.”

How new trenchless technology cuts costs and enhanced safety at Severn Trent

The Severn Trent water treatment works near the village of Cropston lie on the edge of Bradgate Park in the Charnwood Forest in Leicestershire. Here the rising main undulates, with the ultimate discharge location at an elevation lower than the pump station.

Engineers working at the site suspect airlocks caused by this uneven environment, in addition to wastewater arising from the processes on site, may have been the reason for the varying flow rate of the pipeline. Every two years or so, a team would tanker flows and would ice pig the pipeline. Following the operation, the flow rate would improve. But within months they were back to square one, with disruption once again returning restricting the disposal of wastewater from the site.

Not only was this frustrating for the team at Severn Trent, but it could also prove costly long-term too, with no obvious solution to overcoming the recurrent disruption to the flow rate. An alternative method of servicing the main was explored.

Network Operability Specialist, Andrew Warren, from Severn Trent had first been introduced to Quick-Pig for rising mains in 2022 by Nico Hindriks of Reinert-Ritz at No-Dig Live.

Unlike traditional pigging methods, the Quick-Pig uses a compact station that can be operated from the ground surface. No entry via a sewer shaft is necessary, and there is

no need to worry about slippery steps or fermentation gases.

Pigs can be quickly inserted via a launcher and received with another station using the Quick- Pig receiving accessory unit made of PE 100 and V4A stainless steel. This can be inserted in the station without disrupting the operation. Quick- Pig already has a strong pedigree in Germany, where it has been used in over 1,500 installations and is now considered for all new rising main pipeline installations.

Here in the UK, the Severn Trent team decided to trial the technology on a 2km, 80mm MDPE rising main pipeline. Two Quick-Pig stations were planned for the first test clean. These were completely installed in one day at a cost estimated at around £20,000. The team planned the Quick- Pig access points to ensure the pipeline could be cleaned and inspected without the need to enter a manhole at any point along the line.

Quick-Pig stations are designed for 90 mm PE100 pipelines,

with dome heights of 900 mm or 1,200 mm. Access is through a dome cover at road level, leading to an insert locked into the pipeline with a pressure-tight bayonet and quick coupling for easy flushing. A trial in January 2025 showed the system could replace a full ice-pigging team: two operators can now service the entire rising main in under three hours. This has cut costs at Cropston, simplified maintenance, and boosted flow rates from about 11.5 m³/hr to 17 m³/hr.

The Quick-Pig station provided a convenient and safe solution for servicing the rising main, but it also delivered substantial cost savings. During a 5-year AMP period, regular ice-pigging every 12 months would cost an estimated £19,000. By installing two Quick-Pig units on one 2km rising main at roughly the same price, the annual servicing cost dropped to only £2,000 with more regular maintenance intervals. This investment will lead to significant long-term savings, making Quick-Pig a highly cost-effective alternative.

Major upgrade to ageing water mains in Partridge Green

Amajor upgrade to the water network is set to get underway.Southern Water will replace 4.5km of ageing water mains in Partridge Green, West Sussex, using ‘no dig’ technology to minimise disruption.

The project aims to address frequent bursts and discoloured water issues by upgrading infrastructure that is up to 80 years old.

Jonathan Poll, project manager at Southern Water, said: “Some of the water mains are made of cast iron and other materials. They have been in the ground for around 80 years and despite regular maintenance they are beginning to show their age.

“

Some of the water mains are made of cast iron and other materials. They have been in the ground for around 80 years and despite regular maintenance they are beginning to show their age

This replacement project will reduce the risk of discoloured water coming through customers’ taps and will also reduce the risk of bursts, leaks and interruptions to the water supply.”

The scheme began in August 2025 and is scheduled for completion in October 2026.

To reduce the impact on residents and businesses, Southern Water will use trenchless technology, including directional drilling to tunnel beneath roads and pavements. However, in areas where tunnelling is not possible, excavation will be required.

The project will be carried out in eight phases, with a combination of traffic lights and road closures in place throughout the works.

Southern Water serves 2.7 million water customers and provides wastewater services to 4.7 million people across Kent, Sussex, Hampshire and the Isle of Wight.

PEARPOINT systems are designed to excel in harsh environments, delivering unmatched reliability and adaptability for sewer inspection professionals.

From rugged terrains to urban settings, PEARPOINT’S innovative designs ensure seamless performance, minimizing downtime and maximizing efficiency.

With modular components that are easy to swap or upgrade, our equipment evolves with your needs, making it the ultimate partner in the field. When the job gets tough, PEARPOINT gets tougher.

Queens Quay essential sewer improvements progressing well

NI Water is pleased to confirm that Phase 2 of essential Sewer Improvement Work at Queens Quay, between Harbour Square Roundabout and Strand Road Roundabout is nearing completion. All pipelaying and associated civil engineering works, carried out by our contractor GRAHAM, are scheduled for completion by the end of this week, and we anticipate that the road will be reopened - subject to favourable weather conditions. Final reinstatement work will be completed under an off-peak localised lane closure after the full reopening of the road.

This major programme of improvements is part of a wider programme of investment to upgrade the wastewater network serving the city and has already seen over 1,100 metres of the Culmore Trunk Sewer relined between Foyle Road and Queens Quay to strengthen the sewerage network and help protect against sewer collapses, blockages and reduce the risk of out-of-sewer flooding.

Kieran Grant NI Water Project Manager said:

“NI Water is pleased to announce that this essential work is progressing well and is scheduled to be completed by the end of this week, with the reopening of the A2 Queens Quay Road by Friday 19th September.

“The project team engaged a specialist crew to carry out major relining works across the majority of the scheme,

utilising underground trenchless techniques to minimise disruption throughout the city. This approach allowed us to avoid major road closures and significantly reduced inconvenience for residents, businesses, and visitors. In fact, it shortened the overall project timeline by up to nine months.

“Crews used trenchless (underground) methods to accelerate progress, eliminating the need for large open-cut trenches and further reducing disruption. Our contractor also facilitated the temporary reopening of Queens Quay to accommodate key city events such as the Foyle Cup and the Apprentice Boys March. Additionally, work was completed in sections during night time hours between Harbour Square Roundabout and Strand Road, as well as between Queens Quay Roundabout and Lower Clarendon Street to expedite delivery.

“This essential work will improve the efficiency of the network, helping to accommodate future development and economic growth in the city for many years to come.”

NI Water and our contractor GRAHAM appreciate work of this nature is disruptive and thank the public for their continued patience and cooperation as we complete the final stages of the improvements. The city will benefit from this scheme for many years to come.

The project team appreciates the co-operation of the wider public in ensuring that children do not play in or around any site or machinery. Working areas will have warning signs in place to protect the public from any hazards. The public are advised to stay out of these working areas for their own safety as we work to complete the scheme.

Bluelight Lining: Illuminating a trenchless pioneer

By Austen Lees, Editor, Trenchless Works

“ Even a small difference in light penetration can significantly affect cure quality. That’s why compatibility and control are essential

Earlier this summer I visited Bluelight Lining’s Northampton facility to meet Director James Stern. His history with the company reveals how quickly he recognised the potential of LED curing technology.

James first encountered Bluelight as a customer, working on contracts including the Anglian Water frameworks. When Bluelight gmbh (part of Denmark-based Aarsleff A/S) considered launching in the UK, his strong working relationship with the German and Danish teams placed him at the front of the queue. In 2018 he placed the first UK order, rigorously testing the solution for 12 months before becoming the official sole UK supplier in 2019.

As demand grew, James saw that relying on pre-impregnated liners from Denmark would be too restrictive, especially with Brexit approaching. Investment followed in a Northampton impregnation line, capable of processing up to 10,000m per month, giving Bluelight the capacity to scale in the UK.

Technology and performance

The efficiency of Bluelight’s LED curing system has been a major driver of growth. James notes that installations are often two to five times faster than other systems. Today, Bluelight systems are used by contractors including ARM Pipetek, Blue House Services, Drain Lining Solutions, FM Conway, Pipeline Drain Solutions, and ESH Glanville Trenchless.

The solution is distinctive:

• Revolutionary LEDs operating at 450 nm wavelength.

• Flexible felt carrier with PU coating and high-

strength glass liners.

• Styrene-free vinyl ester resins using a patented photo-initiator that reacts only to the LED wavelength.

This technology has now been used in more than 90,000 installations, with success rates of 95–99% compared to around 45% for standard UV curing. Approvals include WRc (UK), DIBt (Germany), and CSTB (France), underlining Bluelight’s focus on quality and certification.

James stresses that the system is most effective when used as a fully integrated package: “Even a small difference in light penetration can significantly affect cure quality. That’s why compatibility and control are essential.”

Sustainability challenges

Bluelight also incorporates a significant proportion of

recycled PET materials in its liners. James acknowledges challenges around cost and availability but believes those already adopting recycled content will be best placed as regulation and customer expectations tighten.

The wider issue, he argues, is that while water companies face pressure to use greener technologies, the sheer scale of work and pressure on budgets makes it difficult to adopt solutions with higher upfront costs. “Everyone wants to be greener, but no one really wants to pay for it. In the end, consumers will need to accept a more realistic cost for water and sewerage services.”

Certification and quality assurance

Certification remains a live debate. >

Bluelight has drinking water liners certified in multiple countries, New Zealand, Australia, Germany, Denmark, Norway, Canada, yet these cannot be used in the UK without Reg 41 approval.

James also questions the partial certification of systems: “What’s the point of certifying a liner and then curing it with an uncertified system? That creates a ticking time bomb of poorly cured liners.”

For him, the solution lies in tighter monitoring, certified installers, and full adherence to Water Industry Specifications (WIS). Bluelight’s system, with pre-set curing parameters for each liner size and thickness, is designed to prevent corner-cutting. Their 12-year partnership with Anglian Water, without a single failed liner, demonstrates the value of rigorous standards.

Looking ahead

Bluelight continues to innovate. Recent developments include a dual-core light-head and new tools to extend system capability for thicker, longer liners. A non-entry measuring device for pipe diameters will deliver safety benefits by reducing the need for confined space access.

The company is also expanding its Northampton site, targeting 20% revenue growth this year.

A new impregnation plant is planned, doubling capacity to 20,000m per month and adding redundancy to safeguard production.

“Our commitment to customer satisfaction and quality is built into everything we do,” James says. “That philosophy is carried through every stage by the Bluelight Lining team.”

Closing thoughts

Spending time with James underlined Bluelight’s mix of technical innovation, integrity, and long-term investment. With sustainability, certification, and new product launches high on the agenda, the company looks set to remain a pioneering force in trenchless rehabilitation.

Working with IPA Products: From the garage to the underground

The products of IPA Bauchemie have established themselves as reliable solutions in both private households and professional environments. Their unique combination of durability, ease of use, and technical performance makes them suitable for a wide range of applications, from small-scale DIY projects to large industrial operations. In private households, IPA materials are often chosen for flooring and basement renovations. Homeowners benefit from products that are not only functional but also straightforward to apply, even without professional experience.

Andreas N., homeowner from Hesse (Germany) and in-house employee in the trenchless sewer rehabilitation sector, talks about his experiences with IPA products:

‘‘When people hear about construction materials, they often think of something complicated and reserved for professionals.

My own experience with IPA products taught me that this is not necessarily the case. What started as a small project in my garage showed me how these materials can be applied both at home and in much larger professional contexts.’’

Andreas continued: ‘‘I began with a fresh concrete floor that needed a protective coating. At first, I tried spreading the material with a roller rake, but soon realized that a water squeegee gave me a smoother finish. Like many first attempts, there were small mistakes, some uneven areas, a darker spot where I used leftover material, and the question of how thick the layer should be. But the process itself was straightforward: grinding the floor, cleaning it thoroughly, priming, sanding with quartz, and finally applying the coating. The result was not perfect in appearance, but it was solid, watertight, and exactly what I needed for a functional garage.

What struck me most was how approachable the products were. I am not a professional

“ When

people hear about construction materials, they often think of something complicated and reserved for professionals. My own experience with IPA products taught me that this is not necessarily the case. What started as a small project in my garage showed me how these materials can be applied both at home and in much larger professional contexts.

installer, yet I managed to complete the project with simple tools and a bit of patience. Friends and neighbors who stopped by were curious, often surprised that such a clean and durable result could come from a DIY effort.’’

On the other end of the spectrum, these very same IPA products are used by professionals in business-tobusiness projects. Instead of a single garage floor, entire warehouses, production areas, or infrastructure elements are coated and protected. The principles remain the same, careful preparation, the right materials, and methodical application by the experts.

A striking example is trenchless pipe rehabilitation. Here, IPA supplies products that allow entire sewer lines to be renewed without digging up streets.

Andreas Neudert - Before his renovation

The concept reminded me of my own project: preparing the surface, applying the material, and sealing it for long-term durability. Only the scale is different, instead of protecting a floor, the aim is to restore pipelines underground, efficiently and without major disruption.

What becomes clear is that IPA products are designed to perform under a wide variety of loads, from the light wear of everyday household use to the heavy demands of industrial machinery and municipal infrastructure. Their adaptability across such different scales makes them a practical choice for individuals as well as professionals.

The versatility of IPA products in private and professional applications

IPA products have established themselves as reliable solutions in both private households and professional environments. Their unique combination of durability, ease of use, and technical performance makes them suitable for a wide range of applications from small-scale DIY projects to large industrial operations.

In private households, IPA materials are often chosen for flooring and basement renovations. Homeowners benefit from products that are not only functional but also straightforward to apply, even without professional experience. A freshly coated garage or cellar floor demonstrates how IPA coatings create resilient, watertight, and easy-to-clean surfaces. Proper surface preparation, such as grinding, cleaning, and priming ensures long-lasting adhesion and results in a finish that withstands everyday use.

Many homeowners appreciate how these systems transform functional spaces into clean, bright, and durable areas, adding value and comfort to their property.

At the same time, IPA products are widely trusted in business-to-business contexts. Professional contractors and industrial clients rely on the same core product qualities but on a larger scale. Whether in warehouse facilities, production halls, or infrastructure projects, the consistent performance of IPA materials ensures safety, reliability, and long service life. Professionals particularly value the efficiency of these solutions, as they allow for predictable workflows and reduced downtime.

A special field of application in which IPA has developed a strong reputation is trenchless pipe rehabilitation. In this sector, the company provides advanced products that enable efficient, non-invasive

restoration of underground infrastructure. The principle is similar to surface renovation in private projects: preparation, application, and curing lead to a sealed, durable result. The difference lies in scale and complexity — instead of a garage floor, entire pipelines are restored without the need for excavation. This innovative approach saves time, minimizes disruption, and significantly reduces costs for municipalities and businesses alike.

The broad applicability of IPA materials shows how seamlessly private and professional worlds intersect. From the homeowner who wants a durable basement floor to the contractor responsible for rehabilitating a city’s sewer network, IPA provides solutions that deliver quality, longevity, and trust.

After the renovation

Bespoke GRP liner brings new life to Scottish culvert

When it comes to rehabilitating buried infrastructure, there’s rarely such a thing as a standard job. Every structure is unique in age, condition, environment, and geometry, which means that rehabilitation demands solutions as unique as the challenges themselves.

That philosophy was put into practice in Scotland where a corroding ARMCO culvert beneath a busy highway required urgent attention. The project became a showcase for Channeline’s ability to design and manufacture tailor-made glass reinforced plastic (GRP) liners to precise specifications, delivering a structural solution that avoided the disruption of road excavation and eliminated the need for costly over-pumping.

A culvert at risk

The 45-meter culvert, measuring 1.2m in diameter and sitting 3m beneath a busy highway, was showing clear signs of rust and structural deterioration. The situation demanded swift action to prevent further decline and to safeguard the highway above.

At first glance, a CIPP UV lining solution might have seemed the obvious route. But closer examination revealed the complications: achieving a dry environment would have required overpumping, bringing delays, disruption, and spiralling costs. A more flexible, less invasive approach was needed.

The Channeline advantage

Channeline has built its reputation on a simple but powerful USP: the ability to manufacture liners to any shape and any size for a precise fit within the host structure.

This design freedom enables engineers to overcome complex rehabilitation challenges where other methods struggle.

For this project, Channeline manufactured a GRP liner to match the exact profile of the deteriorating culvert. Because the system can be installed in flow, the project team avoided the costly and disruptive over-pumping operations that CIPP would have required. The result was a faster, smoother project with minimal impact on road users.

Seamless manufacture and installation

Once the liner was manufactured to Channeline’s exacting standards, it was delivered to site for installation. iLine Technologies, specialists in trenchless rehabilitation, undertook the installation. Thanks to detailed planning and precision engineering, the works were completed efficiently and on schedule.

Within weeks, the failing culvert had been transformed into a structurally sound, corrosionresistant asset with a service life measured in generations.

More than just a fix

This project was more than just a repair; it was a demonstration of how innovative trenchless technology can solve complex problems with minimal disruption. For iLine and Channeline, it was yet another example of how collaboration and custom engineering can overcome the limitations of traditional methods.

For municipalities and contractors worldwide, the message is clear: when every structure is unique, only a bespoke solution will do. For more information about custom GRP liners, visit channeline.com

Setting a new benchmark in rail infrastructure

Alphaliner RL brings trenchless pipeline rehabilitation to railways.

Pipelines underneath trackbeds are among the most complex places for trenchless rehabilitation, with vibrations caused by the trains above and the impact of heavy pressure making them uniquely challenging.

With the Alphaliner RL, however, RELINE has devised a new solution that is designed precisely for these conditions – it is the first-ever UV-cured liner to be granted product-specific authorization from Deutsche Bahn.

Obtaining approval from Deutsche Bahn AG, the Alphaliner RL was specifically designed over a multi-year process to meet the unique product requirements within the railway track structure and underwent extensive material testing.

Among other things, the material quality and resistance to vibration loads (proof of longterm vibration durability) were tested. “Our goal was to develop a product that reliably meets the special conditions within the railway track structure while also overcoming all regulatory hurdles,” explains Philipp Bergmann, Head of Sales at RELINE. “The product-specific approval by Deutsche Bahn AG for use within the railway track is a milestone that offers planners and operators of both railway-owned and third-party crossing infrastructure new trenchless rehabilitation options and regulatory certainty.”

Regulatory reliability for use under railway traffic loads

The use of construction products and the application of construction methods under railway traffic loads are governed by relevant regulations and administrative provisions and monitored by the Federal Railway Authority (EBA).

The criteria for the use of CIPP liners have been defined in coordination with the EBA and are described in the “Planning Guide for Pipeline Rehabilitation” issued by DB InfraGO AG (formerly DB Netz AG; December 2022).

Construction products may be used without specific approval from the EBA, without case-bycase approval (ZiE), and without internal company approval (UiG), provided they are suitable for the intended use and have

“ Our goal was to develop a product that reliably meets the

special conditions within the railway track structure while also overcoming all regulatory hurdles

a general technical approval (abZ) issued by the DIBt.

Technically strong down to the tiniest detail

With nominal widths between DN 200 and DN 800 and lengths of up to 280 meters, the Alphaliner RL already covers a broad range of uses and, what is more, it will also be available for diameters up to DN 1200 from 2026 onward. This is complemented by a full set of standard structural calculations and a successful long-term fatigue test, both of which prove the liner’s durability under cyclical vibration and pressure loads.

The new Alphaliner RL maintains the established structural integrity and material standards of its product

family, including high strength, consistent UV curing, and a smooth interior surface that ensures sustained hydraulic performance. Additionally, it incorporates all advantages of RELINE’s trenchless Alphaliner technology, such as reduced construction periods, minimal cross-sectional loss, lower environmental impact, and limited disruption to the surrounding community.

Reliable planning and implementation

The Alphaliner RL is already raring to go, with the first few invitations to tender already drawn up and published in partnership with the project management teams at Deutsche Bahn.

This is making planning and implementation much easier and laying clear foundations for future projects.

The Alphaliner RL, like other RELINE solutions, is part of a complete system—not just a standalone product.

Along with manufacturing and delivery, RELINE provides support for tenders, sizing, and installation. “We accompany our partners throughout the whole project so that rehabilitation work inside the trackbed can be done efficiently, safely, and predictably,” says Christian Pfaff, Area Sales Manager Germany.

NO-DIG BRINGS WIND ENERGY ASHORE AT NORDERNEY

Trenchless technology in action for Germany’s offshore grid connection, with HDD casing support from TRACTO’s GRUNDORAM TAURUS.

One of the defining challenges of the energy transition is how to bring renewable offshore power to land without damaging sensitive coastal environments. Germany’s BalWin1 and BalWin2 offshore grid connection systems are a case in point: designed to transport 2,000 megawatts of electricity each, enough to supply around four million people, from North Sea wind farms to the mainland grid.

The route passes beneath the island of Norderney in the Lower Saxony Wadden Sea National Park, a UNESCO World Heritage site. Here, trenchless technology is being deployed to minimise impact on the protected dune and mudflat landscapes.

Engineering

on a massive scale

Transmission system operator Amprion has commissioned contractor LMR Drilling to deliver 18 horizontal directional drilling (HDD) installations for protective pipes that will later house the submarine cables.

Work is being delivered in three phases:

• 2025: six HDD bores from the island towards the southern mudflats and mainland.

• 2026: HDDs northwards towards the offshore converter platforms.

• 2027: crossing of the mainland dyke.

Each bore exceeds one kilometre in length, drilled by maxi rigs with thrust and pull forces of up to 450 tonnes. The project site “At the lighthouse” covers 14,000 m², with cranes, storage, and a 10-metrehigh noise barrier shielding neighbouring campsites. Pontoons anchored in the mudflats provide logistical support for pipe and material transport.

Stabilising the ground with casing pipes

The sandy soils at the entry points posed a particular challenge. To create stable conditions for the HDD rigs, TRACTO’s GRUNDORAM

TAURUS rammer was used to drive 800 mm diameter, 24 m long steel casings into the drillable layers.

Dynamic pipe ramming transfers impact energy directly to the pipe, pushing it forward while soil collects inside. For HDD applications this “conductor barrel” method ensures precise casing installation at the correct angle, in this case, exactly 14° to match the bore path.

Although often associated with pipeline installation, ramming machines are increasingly used as HDD Assist tools: to drive conductor casings, free stuck drill rods, or support pipe pulls. >

On Norderney, the TAURUS enabled LMR to install one casing per day, with each active ramming sequence lasting only around three hours.

Protecting a sensitive environment

Environmental stewardship was at the heart of the project design. Construction on Norderney can only take place between July and September each year to avoid disturbing breeding bird species in spring and to minimise the risk of autumn storm surges.

Strict “zero discharge” rules apply, no substances may escape into the mudflats or dunes. HDD was selected because it requires only limited surface works and significantly reduces disruption compared with open-cut methods.

Noise management was also essential. Norderney is a popular holiday island, and the project site lies close to busy campsites. To reduce disturbance, ramming was restricted to set working windows between 8:30 a.m. and 7:00 p.m. The combination of careful scheduling and the noise barrier helped keep disruption to residents and visitors to a minimum.

Precision installation

Each casing consisted of two 12 m sections welded together during installation. Heavyduty cranes placed the pipes into custom-built guide rails, with the TAURUS rammer aligned to the bore path to within centimetres. Once the first segment was driven deep enough, the second was welded on and installation continued until the full 24 m length was in position.

This was the first time LMR undertook the ramming operations themselves using their own TAURUS unit. To ensure success, TRACTO specialists provided on-site training and support during the start-up phase. The team quickly mastered the method, achieving a consistent output of one casing per day, a crucial factor given the limited seasonal window for works.

Phased delivery to 2031

While the ramming operations were still underway, preparation began for the HDD rigs that will drill the pilot bores along the specified cable routes. Once these are complete, protection pipes will be installed from the mudflats, with the steel casings reused for subsequent phases.

The two systems are scheduled for commissioning in 2030 (BalWin1) and 2031 (BalWin2), bringing the projects online one and two years earlier than originally planned.

Wider

context: trenchless in the energy transition

The Norderney project illustrates the growing role of trenchless technology in Europe’s energy transition. Offshore wind expansion

targets are ambitious: Germany alone plans for 30 GW offshore capacity by 2030, while the UK is aiming for 50 GW. To deliver this, new offshore grid connections and land-based distribution upgrades are essential.

For contractors and technology providers, this creates significant opportunities. HDD and HDD Assist techniques, including conductor casing rams, rescue methods, and precision guidance systems, are increasingly recognised as vital tools for minimising environmental impact and enabling power projects to proceed in sensitive locations.

Conclusion

BalWin1 and BalWin2 show how HDD and associated trenchless techniques can support largescale energy projects while balancing environmental protection and community sensitivities. With Amprion leading the transmission scheme, LMR executing the HDDs, and TRACTO technology providing essential casing installation support, the project demonstrates the adaptability of trenchless methods in one of Europe’s most challenging natural and cultural settings.

With TRACTO’s GRUNDORAM pipe rammers, you can install steel pipes up to 4,000 mm 0 with an impact energy of up to 40,500 J in any type of soil. The powerful rammers can also solve problems that arise during complex drilling projects using HDD Assist & Rescue methods. NEED SUPPORT WITH YOUR PIPELINE PROJECT?

Drilling through tough ground conditions: Rock, clay and everything in between

Insights from Vermeer UK on adapting HDD techniques to different

soils

“ Effective fluid management is the best defence against clay, keeping tools free from adhesion and the bore stable.

Horizontal directional drilling (HDD) has transformed how utilities and pipelines are installed, but no two projects are the same. Soil conditions can vary dramatically even within a single bore, creating very different technical challenges for crews on the ground.

From abrasive rock to sticky clay or rapidly changing mixed soils, difficult ground conditions can slow progress, damage tooling, or compromise bore stability if not managed effectively.

Drawing on decades of experience, Vermeer UK shares practical guidance on how to prepare for, and successfully drill through, the most common tough ground scenarios.

Rock: slow progress, steady control

Solid rock presents one of the toughest environments for HDD. Its high abrasion and resistance require tooling designed specifically for these conditions. Carbide-tipped drill heads, rock reamers, and downhole hammers are standard solutions that withstand the punishment of rock formations.

In rock, progress will inevitably be slower, but patience and precision are vital. Applying steady thrust while avoiding excessive force prevents unnecessary wear or breakage.

High-viscosity drilling fluids also play a key role by cooling tooling, suspending cuttings, and transporting them effectively out of the bore.

Clay: sticky, swelling, and unpredictable

Clay may appear softer than rock, but it brings its own set

of complications. Sticky clays can adhere to tooling, causing blockages or even stalling progress. In reactive clays, swelling can constrict the bore and increase torque on the drill string.

The best defence is effective fluid management. Low viscosity, lubricating muds reduce adhesion, while maintaining consistent circulation prevents build-up.

In highly reactive conditions, stabilising additives can be introduced to improve flow, reduce swelling, and keep the borehole stable.

Mixed and variable soils: adapting on the fly

Few HDD projects progress through a single soil type from entry to exit. More often, drillers encounter transitions, for example, clay to rock, sand to gravel, or mixtures of cobbles and fines. These variations can disrupt steering, fluid returns, and tooling performance.

A versatile approach is essential. Crews need to anticipate changes in advance, keep contingency plans for switching tooling mid-bore, and adjust drilling fluid properties in real time. Continuous monitoring of torque, thrust, and returns helps operators detect shifts early and respond before problems escalate.

Best practices for drilling through tough ground

While every site is unique, a handful of best practices apply across conditions:

• Carry out a geotechnical survey before drilling to understand soil profiles and likely transitions.

• Select the right tooling for the ground and keep spares on hand to minimise downtime.

• Optimise drilling fluid mix for lubrication, stability, and cuttings transport.

• Monitor torque, thrust, and fluid returns continuously to identify changes quickly.

• Train crews in adaptive techniques so they can respond effectively when conditions shift.

Following these steps gives contractors the best chance of maintaining productivity and completing bores successfully, even in challenging ground.

The value of preparation and partnership

Tough conditions don’t have to derail HDD projects. With the right planning, tooling, and drilling fluid management, contractors can achieve reliable results across rock, clay, and everything in between.

Vermeer UK works alongside HDD professionals nationwide, providing equipment, tooling solutions, and industry expertise.

From planning guidance to on-site support, the company helps contractors adapt their approach and deliver successful outcomes in every soil condition.

This rock drill features dual rod technology that uses an inner rod to provide torque to the drill bit, while the outer rod offers steering capability and rotational torque for reaming. The combination provides powerful downhole cutting action and the flexibility to select the appropriate tooling to best match the ground conditions, which can allow the entire install to be completed with one machine.

TBM breaks through on Bangkok water supply tunnel

A4.39m-diameter Terratec EPBM has broken through on the Ninth Bangkok Water Supply Project in Thailand.

The breakthrough was achieved June 23 and marks completion of a challenging 3.76km tunnel drive under a major highway – delivered with surface settlement maintained within controlled limits despite complex geological conditions.

EPB TBM S105 was customengineered to tackle the geotechnical challenges of the project alignment. Featuring

a soft ground cutterhead with a spoke-type arrangement, injected tungsten carbide cutting tools, and a maximum cutterhead rotation of 2.4RPM, the machine was tailored to manage Bangkok’s notoriously variable soil conditions, including fine sand, clay, and high groundwater pressure.

Terratec S105 is one of three EPBMs supplied for the Ninth Bangkok Water Supply Project. The Metropolitan Waterworks Authority project is designed to expand and upgrade the city’s potable water distribution network.

The project, managed by contractor Italian-Thai Development PCL, includes more than 9km of tunnelling in total.

Designed to work within the constraints of densely populated urban areas, TBM S105 was equipped with active articulation, tail skin grouting, and automated bentonite and foam injection systems to ensure minimal surface impact. The project involves a total 9km of tunnelling.

Ground Investigation – Specifying for sustainability

By Lee Healey, Chair of the British Drilling Association T&S Sub-Committee

There is a growing imperative in our industry to undertake Ground Investigation (GI) in a more sustainable manner. Whilst the responsibility for reducing carbon emissions and improving environmental performance has often been placed on contractors, the reality is that those specifying and designing the investigation have a central role. To achieve tangible benefits, it is time to think creatively and holistically about how we specify, plan and execute GIs.

Rethinking equipment

Innovations such as rig idle limiters; timers and the consideration of alternative fuel types all contribute to reducing overall emissions.

However, whilst these incremental steps are valuable, they alone will not help us meet stringent Net Zero targets. Some clients, whose budgets permit, may well consider

introducing electric vehicles and drill rigs. Current experience suggests that limited working time, hefty battery packs and additional transport costs remain challenging, yet as technology advances, we can hope to see improvements. The key is to remain aware that no single technological fix will be a panacea; instead, success lies in addressing the fundamental reasons for conducting GI and how it is planned in the first instance.

Specifying with purpose

Arguably the most practical way to deliver a genuinely sustainable GI is to reflect on why the works are specified in the first place. Too often, Principal Designers and their clients over specify investigations to allow for multiple “options” or to mitigate perceived risks. Whilst caution is understandable, there can be a tendency to proceed without reevaluating the GI scope during the execution phase.

By creating a clear feedback loop between the field team and designers, we can continually assess whether we are doing the right amount of work in the right places. In some cases, scaling the investigation down might save time, energy and resources; in other cases, it may be more sustainable to increase the scope to avoid multiple remobilisations at a later date. Getting it right first time not only reduces cost and frustration but also minimises the unnecessary carbon footprint of repeated site visits.

Collaborative planning and resource management

Beyond specification, there is scope for more proactive resource management. A consolidated, coherent approach to GI across adjacent sites or related projects can make a significant difference. Grouping GIs allows for:

• Efficient Logistics: Better planning of drilling rig movements, the use of

shared haulage and the potential for lodging personnel locally rather than commuting daily.

• Local Labour: Engaging local teams reduces travel distances and supports regional economies.

• Lower Carbon Footprint: Fewer, more organised journeys to and from site decrease emissions substantially.

Such an approach requires open communication and collaboration amongst clients, consultants, contractors and all other stakeholders. Framework agreements often provide a suitable structure to facilitate this alignment, ensuring resources are shared effectively over a series of projects.

Monitoring and remote technologies

Post-fieldwork monitoring offers another opportunity to integrate sustainable thinking. Remote monitoring technology can reduce site visits, saving on fuel and travel time. However,

the initial outlay for equipment is not insignificant, and the technology may not always be the best fit for certain site conditions. For projects where remote monitoring is impractical or cost-prohibitive, simple measures such as travelling by train or bus for manual checks remain a valuable way to cut carbon emissions without sacrificing quality.

Balancing cost and carbon

Making GI more sustainable does not mean compromising on safety or reliability. We need a balanced view of cost versus carbon savings to make informed decisions. One potential avenue is to collaborate with a consultant organisation within the BDA that has access to a carbon calculator. By modelling an “options GI” against a “targeted GI,” it becomes clearer where efficiency and carbon savings can be made, and whether any additional expenditure would be justified by the reduced environmental impact.

Looking ahead

Though the transition to genuinely sustainable Ground Investigation is complex, it presents an exciting opportunity for innovation. From rethinking our materials to refining how we specify, plan and monitor site works, every project phase offers scope to reduce our environmental impact. Achieving Net Zero demands a collective mindset shift— where designers, clients and contractors work together, reviewing and adapting specifications in real time, and making optimum use of resources.

As we in the BDA continue to encourage sustainable practices, it is heartening to see an increasing appetite for change across the industry. There will undoubtedly be challenges, but by embedding sustainability at the very heart of Ground Investigation, we can meet both our environmental obligations and the operational objectives of our clients.

CPD and the value of short courses

Frank Reilly Director JBP’s Trenchless, Training Programme

Continuous professional development in a changing sector

Here at JBP we are continuously reviewing both the content and the approach of our trenchless training programmes.

As the water and wastewater sectors continue to undergo rapid transformation and development to meet the challenges of ageing infrastructure, increasing urbanisation, climate pressures, and the need for more sustainable solutions, it has never been more important to have a workforce that is not only technically competent but also adaptive and forwardthinking.

For those working with trenchless technologies, a field defined by innovation and the application of specialised methods, keeping skills and knowledge up-to-date is critical.

Flexibility for busy professionals

Engineers, contractors, consultants, utility managers, and site technicians alike are constantly balancing

demanding workloads and project deadlines. The luxury of taking extended time out of the office or being off a job site to undertake extended training may simply not be possible, no matter how necessary the training is. Short courses, whether delivered online, in person, or in blended formats, can be scheduled around professional responsibilities. This flexibility means individuals can target specific learning areas without committing to lengthy study programs, making CPD more achievable across all stages of a career.

Access across platforms and locations

Increasingly, short courses are designed to reach participants wherever they are. Digital platforms have complemented, and in many cases replaced, traditional classroom learning. Live webinars, recorded sessions, and interactive e-learning modules provide the opportunity for workers in remote regions or those operating on site to access the same quality training as their

colleagues who have access to physical training centres. In trenchless technologies, where expertise is spread across global networks, this accessibility ensures that lessons learnt in one part of the world can quickly be transferred to another.

Building knowledge step-bystep

The CPD approach is very effective, as it embraces a cumulative approach. Short courses allow professionals to build their knowledge in manageable steps, creating a strong foundation of understanding that can be applied almost immediately and expanded over time. A contractor may begin with an introductory course on pipeline rehabilitation, progress to a workshop on condition assessment, and then advance to specialist modules on UV-CIPP or HDD design. This modular learning approach encourages longterm engagement while steadily raising the competency level across the industry.

Personal and professional development

CPD’s value extends beyond technical knowledge. Short courses also foster broader professional growth. Participants develop transferable skills such as problem-solving, critical thinking, and communication, all essential in multidisciplinary trenchless projects. For individuals, the result means increased confidence and greater career advancement. For employers, it means more effective teams, improved project outcomes, and stronger organisational resilience.

Supporting innovation and best practice

Short courses serve as vital channels for disseminating the latest research, innovations, and international best practices. With trenchless technology evolving rapidly, professionals cannot rely solely on their original training. CPD ensures that the workforce remains up to date with advances in materials, equipment, and standards, helping to safeguard quality, safety, and environmental performance across projects.

CPD is also frequently independently certified, under nationally recognized schemes, and increasingly including short course formats in their certification programmes.

Investing in the future

Continuous professional development through short courses is more than a training option – it is a strategic investment. For the water and wastewater sectors, and especially for trenchless technologies, it strengthens individual capability, enhances organisational competitiveness, and supports the sustainable development of essential infrastructure.

By providing flexibility, accessibility, and cumulative learning, short courses are one of the most effective tools for all trenchless practitioners to maintain professional excellence personally as well as on behalf of their employer, and ultimately to the benefit of their clients.

The future belongs to strategic, human-led, results-driven courses that meet people where they’re at.

A message from the Chair

As we start to enter Autumn our attention within the UKSTT is drawn towards the No-Dig Roadshow in Bristol on October 2nd followed by the awards dinner. This will be our 30th dinner! How time flies.

This year we have had a record number of entries so thank you to everyone that took the time to submit an entry and my sincere congratulations to all the finalists.

The other month I highlighted that the large enforcement packages being levied on water companies by Ofwat does not reduce the amount of essential investment that the companies need to make to upgrade our infrastructure.

I was pleased to see that Dr Dec Downey agreed with the point raised and has followed up with a more detailed opinion piece highlighting how this is dealt with in North America, which seems a lot better procedure with binding consent decrees committing the water companies to specific levels of investment in infrastructure. The full report by Dec can be found in August Trenchless Buzz.

Hopefully we will see this now gain momentum, otherwise there will be even less investment than needed for a better infrastructure. Thank you, Dec.

UKSTT also recently attended the RSM open day, a great opportunity to catch up with friends and colleagues whilst witnessing live demonstrations of the latest technologies. I wish to thank everyone at RSM for their efforts and generous hospitality.

The UKSTT know that there is still a lot of work ahead regarding educating clients and asset owners of the fantastic benefits reaped by using trenchless techniques rather than open cut. With the great support from our members and patrons we are confident of continuing to spread that message.

My thanks as always to Lynn, Linda and Tammy whom along with our council members put in the hard yards towards achieving our charities aims.

Kind regards

Graham

A message from the Chair

Dear ISTT members

I hope this message finds you well. I would like to remind everyone to begin planning your trip to the International No-Dig 2025 Conference and Exhibition in Vancouver. Please check the conference website to register and reserve your hotel room.

During the week, we will hold the International Council Meeting and Trustee Meeting, present our annual awards, and conduct elections. These elections are especially important, as we will be selecting a new Chair, one Vice Chair, and two new Board members. We will also enjoy the Chairman’s Dinner and Welcome Reception, which provide excellent opportunities to strengthen your professional network.

To make our strategic plan more effective, we also plan to meet individually with each affiliated society during the conference. As ISTT members, your input is vital. I encourage you to share your views, contribute to our strategy, and join ISTT committees wherever possible. Remember, ISTT belongs to its members.

Please also check the ISTT event calendar for details of national, regional, and international No-Dig events in 2025 and 2026. This year, I have already attended events in Tianjin (China), Denver (USA), Krakow (Poland), Suzhou (China), Kuala Lumpur (Malaysia), and Jeddah (Saudi Arabia). I am encouraged to see growing bilateral and multilateral cooperation between regional societies in Europe and Asia. These collaborations are helping to develop new technologies, expand business opportunities, and bring together governments, consultants, contractors, and suppliers across regions.

Looking ahead, we are planning new ISTT events in the Middle East, India, and Asia in the coming months. In addition, we will continue to deliver ISTT educational webinars, please watch for notices on the website and register.

Finally, as we continue to develop our new ISTT website, we welcome your feedback and suggestions. Our aim is to provide you with the best possible service through this new platform.

I look forward to seeing many of you in Vancouver.

With best regards,

ISTT educational webinar

Optimising Thermoplastic Lining with PE 100 and PE4710 for Potable Water and Wastewater

Date: 12 November 2025

Time: 14:00–15:00 GMT | 15:00 CEST | 09:00 US EST

Speaker: Steve Brogden, Managing Director, Die Draw Ltd (UK)

Overview

Pipelines made from cast/ ductile iron, steel, PVC, GRP, or concrete inevitably deteriorate over time due to corrosion, leakage, or loss of toughness. This can lead to reduced flow, water loss, and in potable water systems, diminished quality. Asset owners must decide whether to decommission,

replace, or rehabilitate, with open-cut replacement often proving costly and disruptive.

Slip-lining with PE pipe is one rehabilitation option, but it reduces flow capacity. A more advanced alternative is the swaged lining / die drawing process, where a polyethylene liner is engineered to fit tightly inside the host pipe, maintaining, and in many cases improving hydraulic capacity.

Design optimisation

Well-established methodologies exist for stand-alone PE 100 and PE4710 pressure pipes in water and gas applications. However, these conservative fully structural designs often require thick liners, which can be economically prohibitive and limit flow. By applying advanced design principles, thinner interactive liners can be specified. These liners share load with the host pipe, focusing on gap bridging, hole spanning, and collapse resistance rather than full hydrostatic strength. As a result, liners as thin as SDR/DR 41 — or even thinner, may be possible, compared to the much thicker SDR 11 typically used.

Benefits and recent advances

Modern modelling tools, including LiDAR surveys and improved temporary works design, now allow for the installation of longer, continuous lengths of liner with greater accuracy and predictability.

This enables:

• Increased flow capacity

• Reduced installation costs

• The ability to navigate bends within host pipes

• Less disruption to communities

• Significant reductions in carbon footprint

Two recent projects, one for a large-diameter potable water main and one for medium-diameter wastewater rehabilitation, will be presented to demonstrate these principles in action and share lessons learned.
