ENV to smoke test portions of Waimānalo wastewater system

HONOLULU - The City and County of Honolulu Department of Environmental Services (ENV) plans to smoke test a portion of the wastewater collection system in the Waimānalo area Aug. 19 to Sept. 6, 2024, weather permitting.

The testing is between the hours of 8 a.m. to 2 p.m., and is part of ENV's preventative maintenance program to prevent rainwater (inflow and infiltration) from entering the sewer system.

ENV crews 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.

Test smoke should not enter your home unless you have defective plumbing or dried up drain traps. If you have any seldom used drains, please pour enough water in the drain to fill and create a water seal in the U-trap before Aug. 19, 2024.

Although rare, should a resident observe smoke appearing inside their dwelling during testing, please open all windows to vent the vicinity and contact an onsite ENV crew member. People and pets with chronic respiratory illnesses should be temporarily moved outside as a precaution. The attached map illustrates the area to be tested.
