Preservation where failure isn’t an option.
Water and wastewater facilities are among the nation’s most critical assets. They are essential to public health, environmental protection, and industry. Yet they operate in some of the harshest conditions in infrastructure. Corrosive gases, sewage acids, chemical by-products, and constant abrasion attack steel and reinforced concrete every day, accelerating deterioration, shortening service life, and heightening the risk of failure.
Beyond these physical realities, the sector faces broader pressures. Demand is rising. Regulatory obligations are becoming stricter. Opportunities for shutdowns are limited. At the same time, operators must integrate smarter systems into ageing infrastructure. Together, these factors expose the limits of routine maintenance. Short-term fixes may delay problems, but they do not deliver resilience, compliance, or long-term cost control.
This is where Mattioli’s approach makes the difference. With decades of experience in the water and wastewater sector, we deliver remediation, protection, and lifecycle solutions built to perform in harsh environmental conditions and under strict operational constraints. Our strategies extend service life, reduce reliance on short-term fixes, and provide cost-effective alternatives to replacement — ensuring critical infrastructure remains safe, reliable, and resilient well into the future.
With decades of experience in the water and wastewater sector, we deliver remediation, protection, and lifecycle solutions built to perform in harsh environmental conditions and under strict operational constraints.
Water and wastewater infrastructure operates under relentless pressure. Corrosive gases, chemical attack, constant wear, and limited shutdown opportunities combine to accelerate deterioration and heighten risk.
For operators of treatment plants, pumping stations, and reservoirs, these threats are a daily reality— jeopardising service continuity, compliance, and financial control. When failures occur, the consequences are immediate: disruption, penalties, environmental harm, and escalating costs.
Left unaddressed, these risks compound — shortening asset life, increasing operational risk, and driving up cost.
Mattioli addresses risk across three focus areas —
• Asset condition,
• Lifecycle demands
• Safe delivery
Together, these focus areas ensure nothing is left unmanaged, and each is tackled with precision so every intervention delivers measurable, lasting value.
• Control corrosion & restore concrete integrity
• Seal leaks, waterproof & protect against chemical attack
• Rehabilitate assets to extend service life
• Embed compliance & sustainability at every stage
• Balance capital & operational expenditure
• Monitor & optimise to sustain performance
• Execute safely in live, process-sensitive environments
• Meet strict WHS & regulatory requirements
• Overcome access challenges with engineered solutions
Outcome: The result: assets that are safer, stronger, and ready to perform for decades.
The water and wastewater sector depends on a mix of core facilities — treatment plants, reservoirs, and pumping stations — supported by environments such as chemical storage and control facilities.
Each facility type presents its own challenges, from aggressive chemicals and confined access to strict shutdown limits and compliance obligations.
Drawing on sector insight, Mattioli develops facilityspecific strategies that address these pressures — protecting performance, ensuring compliance, and sustaining long-term reliability.

Structured. Integrated. End to End.
Water and wastewater infrastructure operates under conditions where reactive maintenance is costly and short-term fixes quickly fail. The Mattioli Asset Management Plan (AMP) provides a clear, structured approach to managing and preserving assets across their lifecycle — connecting assessment, planning, delivery, and long-term care in one coordinated process.
Each stage informs the next, ensuring risks are controlled, interventions are timely, and investments deliver maximum value. By closing the gaps between assessment, specification, and works, the AMP keeps maintenance aligned with asset condition and budgets predictable. Continuous monitoring and amortised cost models provide transparency and confidence, supporting better decision-making at every stage.
Whether managing ageing infrastructure, compliancesensitive facilities, or large portfolios, the AMP provides a scalable approach to maintain reliability, control cost, and extend asset life.
The outcome: timely interventions, predictable budgets, and assets that remain safe, compliant, and resilient well into the future.
Assets are managed strategically from assessment through to optimisation.
Rigorous processes identify risks early and address them effectively.
Condition-based interventions preserve asset value, minimise downtime, and maximise longevity.
Facilities remain aligned with regulatory, safety, and industry requirements.
Amortised models provide predictable budgeting and financial certainty.
Investment, time, and effort are directed where they achieve the best outcomes.
A systematic process of review and refinement—driven by performance insights, innovation, and stakeholder input—to extend asset life, improve outcomes, and enhance overall service delivery.

Available as part of our Asset Management Plan, cost amortisation gives asset owners the option to structure maintenance costs across the service life of assets.
By avoiding large, upfront expenditures, this approach creates financial stability, simplifies budgeting, and ensures maintenance can be carried out when it is most effective.
Budget limitations are one of the main reasons maintenance is delayed or deferred. By smoothing costs over time, our cost amortisation model removes this barrier, enabling asset owners to sustain high standards of care without compromising financial health. The result is predictable funding, better decision-making, and the ability to prioritise long-term reliability over short-term constraints.
Structures costs across the service life of assets, improving budget accuracy, long-term planning, and cash flow management.

Minimises exposure to major one-off costs, stabilises budgets, and supports compliance with financial and regulatory obligations.
Encourages adoption of advanced, sustainable technologies by lowering upfront costs and unlocking long-term savings.
In water and wastewater environments, there is little margin for trial and error. Assets operate under chemical extremes, confined access, and live operational pressures that push conventional methods to their limits. To succeed in these conditions, solutions must perform first time, safeguard compliance, and deliver measurable long-term value.
Mattioli’s innovation is proven in the field. We adapt and engineer systems to work where standard approaches cannot — restoring assets once considered beyond recovery, reducing lifecycle costs, and ensuring reliability under the sector’s toughest conditions
Innovation demonstrated through practical outcomes:
Robotic Precision for Safer, Cleaner Refurbishment
Project Context
This project involved the full coating refurbishment of a 65-metre diameter water storage reservoir, including the removal of hazardous internal and external coatings under highly restricted access conditions. The works were performed while ensuring safety, environmental compliance, and minimal disruption to the surrounding facility operations.
Mattioli utilised a remote-operated spider robotic system to remove hazardous coatings from the reservoir’s external surfaces. This eliminated the need for scaffolding, reduced working-at-heights risks, and enabled precision cleaning in difficult-to-reach areas. Ultrahigh-pressure (UHP) water was used in a fully controlled, closed-loop process to capture all waste material and prevent contamination.
Inside the reservoir, a mast climber robotic system was deployed to carry out coating removal on vertical surfaces under confinedspace conditions. This solution minimised manual handling, eliminated airborne contaminants, and maintained worker safety. UHP water was again used in a closed-loop system with full recapture and treatment.
A purpose-built water treatment and recycling plant was established on-site to process all captured UHP water from both internal and external works. The system enabled complete treatment and reuse of water with zero discharge to waste, meeting stringent environmental requirements.
By combining advanced robotic systems with on-site water recycling, Mattioli delivered a safer, faster, and environmentally sustainable refurbishment. The approach reduced labour risks, maintained full compliance, and allowed the reservoir to return to service sooner — with no environmental discharge and a fully refurbished coating system. This project was recognised as a finalist for the Australian Water Association’s Water Industry Safety Excellence Award for its innovation and sustainability outcomes .
As part of a major facility upgrade, a critical tie-in project was required to integrate new treatment plant infrastructure with the existing system. The works had to be completed with restricted access and under strict operational constraints to avoid extended shutdowns or service interruption.
Mattioli designed and installed an in-house engineered geotextile-reinforced lining system that not only protected the internal concrete surfaces but also bridged across moving stainless-steel plates and an HDPE liner interface — an approach rarely attempted in live plant conditions. This bespoke solution was engineered to withstand the chamber’s hydraulic loads, chemical exposure, and dynamic movement without compromising seal integrity.
This innovative approach:
• Reduced project costs by 40% compared with conventional alternatives
• Minimised downtime risk by avoiding full system shutdown
• Extended service life of the chamber and improved overall reliability
• Demonstrated a novel application of geotextile technology, setting a precedent for similar assets
A critical sewage inlet chamber at a wastewater treatment facility had experienced severe concrete degradation and high-pressure leakage, leaving it close to decommissioning. The client required a solution that would avoid full replacement, restore structural integrity, and extend the asset’s service life.
Mattioli delivered a comprehensive, in-house engineered rehabilitation solution that combined three key techniques:
• Precision Crack Injection – sealed high-pressure leaks to restore watertight integrity.
• Concrete Refurbishment – reinstated the structural capacity of severely degraded sections.
• Geotextile-Reinforced Lining System – provided a robust, chemical-resistant barrier to protect the structure long-term.
This integrated approach formed a complete containment and protection system, purpose-designed for the inlet chamber’s hydraulic and chemical demands.
The solution extended the chamber’s service life by 25+ years, avoided the need for demolition and costly asset replacement, and returned the structure to full service. This innovative, multi-layer approach set a new benchmark for sustainable rehabilitation in wastewater infrastructure.
