Smoke testing to be done on the Hanamā‘ulu sewer system in Kauai

Local News

The public is advised that the Wastewater Management Division will perform additional smoke testing on its Hanamā‘ulu sewer collection system next week.

This is a follow up to the smoke testing that was performed in July 2018. Additionally, smoke testing will be performed in Wailua.

Smoke testing will be performed from June 5 to 7, from 8 a.m. to 1:30 p.m. The streets that will be smoke tested include Hanamā‘ulu Road, between Kūhiō Highway and Anai Street, and Papaloa Road, between the north and south intersections with Kūhiō Highway.

Smoke testing uses non-toxic smoke and is helpful in identifying areas where infiltration/inflow (stormwater entering the sewer main) is occurring. The tests will consist of approximately 20 minutes of work at each manhole in the area.

Traffic control, using flaggers, will be implemented in the work areas.

Motorists should drive with caution, expect delays and adjust their travel times as needed.
