(BIVN) – A sewer infrastructure replacement project in Kona will begin on October 15, impacting traffic patterns on and near Hualālai Road.

The $6.4 million Hale Hālāwai Force Main Replacement Project – required under Hawaiʻi County’s Administrative Order on Consent with the U.S. Environmental Protection Agency – will be conducted in five phases, the County of Hawaiʻi reports. Work will start near Hale Hālāwai park at the intersection of Hualālai Road and Aliʻi Drive, and will progress through these separate phases on Hualālai Road between Aliʻi Drive and Kuakini Highway.

Officials say the 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.
