Industrial Services AQS environmental solutions were the first industrial services company in Ireland to introduce the concept of vacuum excavation or air movement on a commercial basis.

DISAB Onsite Vacuum Excavation of Sand and Silt.


he concept of vacuum excavation was first introduced by AQS in 2006 and to date we have completed numerous difficult projects that have resulted in significant savings for our customers, from a time and waste perspective. Our DISAB units can remove heavy sludge, rag, sand, crushed stone and powders from any location, on any

given site. Our trained, highly skilled operatives can maximise the performance of the machines. Typical areas of application include: • Removal of solid material from pump stations, deep sumps and culverts. • Exposure of underground utilities, as the units can remove clay and stone by

C on t a c t u s: 0 5 0 4 5 7 8 0 0

suction. • Remove filter media (sand / activated carbon / resin). • Remove grit, screenings, etc from all applicable areas in water and waste water treatment plants. We can undertake any size project required in any industry type.

Our DISAB vacuum excavation units are used in the excavation of ground areas where there are buried services. The vacuum excavation system ensures that gas lines, power lines, water and sewer lines are not damaged in any way, and they can be exposed safely.

Lagoon Cleaning

The DISAB units have a high tip function which allows them to tip all debris and waste directly into our water tight roll on roll off skips.

Site Decommissioning Due to our broad service offerings, our specialised machinery and trained staff, we can also provide a site / facility decommissioning or decontamination service.

Site Decontamination


n cases where manufacturing, industrial or other facilities need to be demolished or upgraded, AQS can provide a service whereby all hazards are removed from tanks, sumps and all surfaces prior to dismantling or upgrade.

Our site decommissioning teams have experience in a wide range of industries, from pharmaceutical facilities to illegal landfills. Site decommissioning projects are generally very technical and pose significant health and safety challenges, due to the fact

C on t a c t u s: 0 5 0 4 5 7 8 0 0

that anything from hazardous chemicals to bio – hazardous waste may need to be handled during the course of the specific project, and our teams are equipped and trained to do this.

www.aqsso lut io ns .i e 6

Tank and Drain Cleaning Tank and drain cleaning activities are undertaken on a daily basis by AQS.


• Pump station clean outs (including removal of rag, silt and stone). • Cleaning of sewer lines and drains, irrespective of size or location prior to CCTV survey. • Spillage clean up. • Domestic blockages or septic tanks.

ach task commands its own resources and work practices and may involve the use of breathable air, confined space entry procedures or chemical handling procedures. Our extensive and varied fleet allows us to complete any type of drain cleaning project possible, irrespective of material type.

Waste management is generally a large factor in these activities and all wastes removed off site are properly accounted for with certificates of disposal issued upon completion of the disposal process.

Tank and drain cleaning services generally include: • Cleaning of tanks that contain organic waste, solvents, acids, oils, filter media or any other material.

Reservoir Cleaning


Drain Cleaning

e can also provide a service whereby we can remove sludge and other settled deposits from water reservoirs without having to drain the reservoirs. This service is provided by trained divers and specialised pumping equipment – any size reservoir can be catered for.

Sludge Dewatering & Disposal The two main types of sludge dewatering units in our fleet are our MaskoFlex units and our Mobile Centrifuge units.

Centrifuge working at a Water Treatment Plant

Mobile Dewatering at a WWTP


askoflex dewatering units are truck mounted dewatering systems, with an on board polymer dosing system. These are utilised for dewatering septic tanks, small local authority water / waste treatment plants and commercial water / waste water treatment systems. As these

units are truck mounted, they provide increased flexibility to our customers. They can dewater sludge on site, dramatically reducing waste disposal charges by sludge removal on the same day. Mobile centrifuge units - these are larger units designed for more long term

C on t a c t u s: 0 5 0 4 5 7 8 0 0

dewatering projects. The machines that we operate are designed and built to the highest possible specification, and are supplied with chopper pumps, sludge pumps, generators and poly dosing systems (liquid and solid).

Specialised Dewatering AQS carry out a wide range of services specifically related to drainage infrastructure. Our mainline CCTV survey equipment can provide our clients with colour, high resolution CCTV reports, outlining structural defects or any other potentially problematic issues with drainage infrastructure.


long with our standard robotic cameras that enter drains, we have cameras that can float on water (for partially filled drains). In relation to our surveys, our clients are provided with electronic copies of our survey results. Our drain remediation processes include: • Robotic cutting of any intrusions that may be present in drains, such as roots, steel, or scale build up, or any other intrusions that may be present. • Installation of part liners, and full relining systems. Chemical Injection • Relining of leaking manholes and chemical sealing of manholes and drainage network. This involves our specialised chemical injection process – this is a highly skilled system that employs specialised resins designed to eliminate water ingress or seal manholes from chemical or microbiological erosion.

Drainage Networking Testing In conjunction with our drain surveying service, AQS also provide drainage network testing services and a drainage network / asset mapping service.

Site Survey


n many instances, the integrity of a specific drainage network needs to be tested in order to comply with IPC licence conditions - AQS can provide the drain hydrostatic testing service if required. Our qualified civil engineers can conduct an asset survey on sites that are not properly mapped and can generate

AutoCAD network drawings upon request.

Other services include: GPS tagging of assets such as manholes and pump stations. Provision of as-built drawings. Contour mapping. Manhole condition surveys / general network surveys.

• Culvert surveys. • Bund testing services. • Flow metering. In conjunction with our remediation crews, a site can be managed from the initial survey to the final remediation of any issues on site.

Small Scale Services AQS continue to serve local small clients such as private dwellings, hotels, leisure centres, public houses, and retail outlets.

Clearing Blockage in Internal Drain Network Septic Tank Cleaning


ven though we have grown to be a nationwide service provider, we have not forgotten where we came from and still to this day provide our domestic customers with a wide range of services. These services include: • Clearing of blockages in internal drain

networks / sanitary networks. • Cleaning of grease traps. • Clearing of gullies and roof gutters. • Power washing service. • Brick cleaning in driveways. • Septic tank cleaning. • General site clean-up / decontamination. • Pool filter cleaning.

All of our domestic customers are considered to be as important as our large industrial clients and are treated in the same manner. We have a number of small units in our fleet designed to facilitate the servicing of our smaller domestic customers. These units include van packs, power washers, small wet-vacuum cleaners, and a wide variety of hand tools.

Waste Management As a result of our contracting activities, we generate a large volume of organic waste that needs to be recycled at authorised treatment facilities.

Acorn Recycling Composting Facility


s our organisation expanded over the last number of years, we recognised the opportunity of establishing our own waste / environmental consultancy business and it was from this recognition that Acorn Recycling was established. Acorn Recycling is now a

stand alone waste management company, operating a 45,000 tonnes per annum, EPA licensed composting facility in Littleton, Co. Tipperary. The facility is also licensed for the acceptance of animal byproducts (food waste). Other wastes currently being composted by Acorn Recycling include

C on t a c t u s: 0 5 0 4 5 7 8 0 0

sewage sludge cake, brown bin waste, other organic sludges, liquids and organic wastes. In relation to all wastes generated by AQS activities only authorised approved waste contractors are utilised.
