Dye Water Testing Services
Locate and Quantify Defects in Your Collection System. Usually performed in conjunction with internal TV inspections. Dye Water Flooding aides in the location and quantification of specific defects during an evaluation. The procedure consists of forcing non-toxic dye into defects located during smoke testing and manhole inspection. The path of the dye is then documented, and leaks in the sewer lines are located. Manholes with evidence of inflow/infiltration, mainline defects, cross-connections, roof drains and area drains can all be investigated using the dye flooding procedure.

Cross-connections, roof drains and area drains that are suspected of being connected to the sanitary sewer will be positively identified using the dye testing procedure. The dye is forced into defects that were located during other system inspections. The path of the dye is then documented and leaks in the sewer lines are located. Manholes with evidence of inflow/infiltration, mainline defects, cross-connections, roof drains and area drains can all be investigated using the dye flooding procedure. Field documentation and photographs, where feasible, will be used to record all findings.
