Combined Sewer Overflow Surveys

Over the years we have carried out many Combined Sewer Overflow (CSO) surveys for many different industry drivers such as; Shell Fish, Unsatisfactory Intermittent Discharge (UID), Bathing Waters and Un-consented sites.

We are as happy surveying a basic high level overflow pipe (orifice) overflow as a complex CSO with designed storage and complex multi spill level weir arrangements.

We are experienced in identifying location of overflows when existing data is inconclusive, tracing overflow pipes to the ultimate discharge point be that to a Surface Water Drainage system or to an Outfall.

As with all other surveys we carry out there is a range of reporting options available to meet our client’s needs ranging from scanned site sheets to full reports and drawings produced in AutoCAD.
