Dye Water Flooding
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.
