Smoke Testing of Sewer Lines in the Papakolea, Kewalo, and Kalawahine Subdivisions

Posted on Dec 20, 2017 in Media Releases


Underground Services Inc. (USI) will be smoke testing portions of the sewer collection system in the Papakolea, Kewalo and Kalawahine subdivisions between

JANUARY 22 to FEBRUARY 9, 2018
8:30 A.M. and 3:30 P.M. Monday – Friday (Weather Permitting)

The smoke test will be conducted and generally should not affect the public. You do not need to be present.

When weather permits, white smoke is fanned into underground sewer pipes while crews canvass the area to see where the smoke appears. The smoke you see coming from the vent stacks on houses or holes in the ground is NON-TOXIC, NON-STAINING, HAS NO ODOR, WHITE TO GRAY IN COLOR AND CREATES NO FIRE HAZARD.

The 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, about a gallon, in the drain to fill and create a water seal in the plumbing u-trap prior to the test.

Should you observe smoke appearing inside your dwelling during the smoke testing, please open windows to vent out the smoke then contact the onsite USI crew or call our contact numbers listed below.

IMPORTANT! If there is any individual in your home or business who has respiratory problems and is immobile, please notify us prior to testing.

If you would like more information, please contact DHHL project manager Mitchell Kawamura at 620-9278 or consultant R. M. Towill Corp. at 842-1133.
