Pahala Sewer Smoke Test Set for Tuesday

The County of Hawai’i Department of Environmental Management Wastewater Division will conduct survey efforts, including smoke testing, on Tuesday to locate sewer infrastructures in the area of the Old Mill site in Pahala.

Work will begin at 8 a.m. and will last through 3 p.m. in the Maile Street Rubbish Dump Road Junction.

Crews will open manholes on Maile Street and within private properties with sewer mains, diversion boxes, and laterals.

WWD notes that the process of smoke testing includes a simulated non-toxic smoke that will be placed in the sewer system to test the system’s integrity. During the test, smoke may be seen coming out of manhole covers, storm drains, roof vents, and building foundations.

Prior to the test, area residents can conduct prior efforts to prevent smoke from entering their home, including running water faucets in unused sinks, tubs, and drains to fill traps. At least one gallon of water can also be added to the basement floor drain. Those with defective plumbing should consult with a licensed plumber.

WWD officials say the smoke is not a health risk and residents should not be alarmed if they see smoke in their home. Opening doors and windows will assist with ventilation and clear the smoke.

Anyone who does experience smoke should contact a licensed plumber to identify where the smoke is coming from, since sewer gases could also enter the home in a similar manner.
