Smoke-testing under way in Waipahu sewer lines
Advertiser Staff
Crews from the City Environmental Services Department will continue smoke-testing sewer lines on Awamoku, Awaiki and Awanui streets in Waipahu today and tomorrow.The testing is part of the city's continuing effort to prevent rainwater from entering the sewer system. City crews will blow smoke into sewer lines and record where the smoke appears. The smoke used is nontoxic, harmless and odorless. The smoke is not a fire hazard, nor is it a health hazard to humans or pets.
Notification letters have been sent to area residents.
The test locates broken pipes, illegal connections, open cleanouts and other paths for runoff to enter the sewer system. Runoff from heavy rain can overwhelm the sewer system and treatment plants and cause spills.
