Sewer force main replacement project underway in Kailua-Kona

A sewer force main replacement project underway in Kailua-Kona, which began Oct. 15, is causing temporary traffic adjustments on and near Hualālai Road.

Hawaiʻi County’s $6.4 million 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 project — contracted to Alpha Inc. — is scheduled to be completed by October 2026.

It is required under an order from 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 Hawaiʻi County Mayor Kimo Alameda an announcement about the project. “During construction, impacts to traffic and businesses will be mitigated as much as possible.”

Work hours are 7 a.m. to 4 p.m. Monday through Friday, except when shifted to nighttime hours.

Temporary impacts to vehicle and pedestrian traffic, including lane adjustments and closures, are expected throughout the project’s duration.

The project is planned in five phases, with work starting near Hale Hālāwai at the intersection of Hualālai Road and Aliʻi Drive and progressing on Hualālai Road between Aliʻi Drive and Kuakini Highway.

“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,” Alameda said in the announcement.
