HILO, Hawaii (AP) - Big Island officials expect a wastewater treatment plant planned for Naalehu to cost $40.5 million, nearly double the previous price tag.
The Hawaii Tribune-Herald reports the project planned for a site on the side of town toward the sea was previously estimated to cost $20.3 million.
Bill Kucharski, Hawaii County environmental management director, says the project will have more sewer lines than originally planned. The new price tag also includes a 20 percent contingency.
The U.S. Environmental Protection Agency has ordered the Big Island to close large-capacity cesspools in Naalehu by 2022 and in Pahala by 2021, prompting plans for new sewer facilities in both communities.
Kucharski says the Pahala project is estimated to cost up to $30 million.
