We work in urban, rural, sensitive, and high hazard environments.

We work under a range of commercial mechanisms including NEC4, Burgandy, EPC, depending on client needs and project requirements.

Our engineering expertise in surveys, design, construction and maintenance ensures we address a wide range of client issues, ranging from CSOs, network capacity and spills reduction. We work on storm spill reduction (SSR) projects, fitting non-return valves to outfalls. In addition, we deliver growth projects, install new sewer and pipeline diversions. We conduct surveys to assess the asset condition of wastewater assets.

We design, build, and maintain a wide range of wastewater assets, including:

• Large scale tanks, chambers, sludge tanks, prefabricated modular concrete tanks and built in situ-concreate tanks.
• Stormwater management systems (CSOs, tanks, overflow channels, outlets, attenuation tanks)
• Rising mains
• Pumps and pumping station (refurbishment)
• Outfalls
• Wastewater pipelines and sewers
• Nature based solutions including SUDs
• Pipe bridges
• Wet wells
• Access hatches, covers, and frames
