Drainage Surveys

We carry out a full range of drainage and sewerage asset investigations using qualified staff, including manhole asset surveys to STC25 standards, confined space entry, asset mapping, drainage area studies, highway drainage surveys, pollution surveys with drain tracing and dye testing, catchment and threshold surveys and infiltration studies. Our manhole surveys record cover levels, chamber dimensions, pipe depth, material and diameter, and validate connectivity, so you know precisely how a drainage network behaves, not just where it runs. We also identify cross connections where sewage or industrial water is entering surface water systems, a common and costly issue on older commercial and industrial sites.
