We undertake a range of drainage and sewerage related asset investigations. Where necessary we can investigate using trained, qualified and fully equipped confined space teams.

 

Our experience includes the investigation of pollution incidents, cross connection and contamination of sewage or industry process water discharging into surface water drainage networks and watercourses, full drainage asset mapping for industrial, commercial and redevelopment sites, highway drainage mapping, drainage area and impermeability studies.

We’re able to undertake specialist surveys to produce digital ‘as-built​ drawings’ for existing structures such as Storm Overflow’s, Pumping Stations and Culverts. We also carry out manhole asset surveys to STC25 standards providing critical information such as cover levels, chamber sizes, pipe details including; depths, materials, diameters and validated connectivity.​
