Wahiawa Wastewater System Smoke Testing

21 02 2017

The City’s Department of Environmental Services (ENV) will smoke test areas of the lower Wahiawa wastewater system, Feb. 21-March 3, 2017, weather permitting.

The testing, during normal business hours, is part of ENV’s preventative maintenance program to prevent rainwater (inflow and infiltration) from entering the sewer system.

ENV crews will pump non-toxic smoke into sewer pipes, examine and record locations where the smoke escapes.  The smoke is harmless with minimal odor and neither a fire hazard nor a health hazard to humans and pets.

Tests locate broken pipes, illegal connections, open cleanouts and other paths for runoff to enter the sewer system.  Runoff from heavy rain can overwhelm and surcharge the sewer system and treatment plants, causing sanitary sewer overflows.

An advertisement was placed in the local daily newspaper while residents and affected businesses were informed by mail and handouts.  Fire and Police communications centers will be notified at the beginning and ending of each test.
