Sewer Force Main Replacement Project in Kailua-Kona Starts Oct. 15

A sewer force main replacement project will begin in Kailua-Kona on Oct. 15, requiring temporary traffic adjustments on and near Hualālai Road.

The County of Hawaiʻi’s Hale Hālāwai Force Main Replacement Project involves the installation of a new 12-inch sewer force main, rehabilitation of manholes and vaults, installation of a new flow meter, pavement restoration, and related improvements.

The $6.4 million project, contracted to Alpha Inc., is scheduled to be completed by October 2026 and is required under the County’s Administrative Order on Consent with the U.S. Environmental Protection Agency.

“This project replaces infrastructure that is more than 45 years old and will ensure that we maintain reliable wastewater service for Kailua-Kona residents,” said Mayor Kimo Alameda. “During construction, impacts to traffic and businesses will be mitigated as much as possible. We also want to thank the public for its patience and understanding as we ensure that our infrastructure serves our communities well into the future.”

What to Expect

Work hours for the project will be 7 a.m.-4 p.m. Monday-Friday, except when shifted to nighttime hours. Temporary impacts to vehicle and pedestrian traffic, including lane adjustments and closures, will occur during working hours.

The project will be conducted in five phases, with work starting near Hale Hālāwai park at the intersection of Hualālai Road and Aliʻi Drive. The project will progress through these separate phases on Hualālai Road between Aliʻi Drive and Kuakini Highway.
