comprehensive repair and maintenance

Maintenance Solutions

Since 2000, we have been providing comprehensive repair and maintenance services to key water clients across the UK, offering tailored solutions for both clean water and wastewater systems. Our team is highly experienced in managing and maintaining a wide range of asset types, ensuring that clients benefit from reliable, cost-effective services designed to meet regulatory requirements and operational needs.

ensuring safe and efficient water supply networks

Clean water solutions

For clean water systems, we offer a variety of specialised solutions. These include clean water repair and maintenance services that ensure the continued safe and efficient operation of water supply networks. We provide mains burst repair services, responding promptly to urgent situations and minimising service disruption. Our team is skilled in the detection and repair of leaks, using advanced technologies to identify issues swiftly and reduce water loss.

In addition, we carry out large diameter pipe repairs, which require expert knowledge and precision due to the size and complexity of the infrastructure involved. We support mains rehabilitation, including asbestos cement (AC) and mains replacement programmes that improve the overall efficiency and longevity of water networks. Our zonal studies help identify areas for improvement, ensuring that maintenance efforts are focused where they are most needed.

network apparatus maintenance

Clean water - additional services

Our services also extend to network apparatus, where we perform repair, maintenance, and installation work for key components such as hydrants, stop taps, and air valves. These critical elements help maintain pressure, control flow, and enable emergency interventions, so it is essential that they are kept in good working condition. To ensure ongoing network reliability, we offer a standby service, providing rapid-response capabilities for emergency situations.

Our site investigation services are also an important part of our clean water offering, including trial holes, surveys, and asset condition monitoring, which help us assess and manage the health of infrastructure. As part of our commitment to improving water quality and safety, we also undertake lead pipe replacement to ensure compliance with health and safety standards.

We are equipped to perform mains cleaning, using advanced techniques such as air scouring and ice pigging to remove sediment and debris that can accumulate within pipes over time. This helps to maintain the efficiency of the water distribution system and ensures that the water supplied remains of high quality.

Wastewater Solutions

We carry out wastewater maintenance solutions, predominantly for non-infrastructure assets.

Our site audits help clients assess their systems’ performance and identify areas where improvements or repairs may be needed. We also offer asset optimisation services, helping clients get the most out of their existing infrastructure through efficient management and targeted improvements.

Our team is skilled in troubleshooting operational assets and sites, addressing any technical issues that arise in wastewater networks and treatment plants. This includes process testing to ensure that systems are functioning correctly and in line with regulatory requirements. We also specialise in telemetry systems, SCADA, and PLC systems, which facilitate remote monitoring and control of wastewater assets, allowing for real-time data collection and decision-making.

Wastewater - additional services

We also offer the installation and maintenance of critical monitoring equipment, including flow monitors and flow control systems, all of which play a vital role in managing the flow and treatment of wastewater. These systems are essential for detecting and controlling flow variations, ensuring that wastewater is processed efficiently and in compliance with environmental regulations.
