Smoke/Dye Testing

United Survey's fast, inexpensive smoke testing procedure identifies illegal tie-ins to the sanitary sewer system. It also can detect storm water entry through various defects in the sewer system. By inducing dyed waters into driveway drains, down spouts and yard drains, we are able to isolate problems in sanitary systems. Dyed water flooding of adjacent storm sewers and ditches, used in conjunction with our color video inspection, quickly identifies points of storm water entry into the sanitary sewer.
