Updated Honouliuli Wastewater Treatment Plant unveiled
A $536 million upgrade to the city’s 45-year-old Honouliuli Wastewater Treatment Plant in Ewa Beach has been completed, the city says. The completed work at the wastewater plant — which serves communities from Halawa to Makakilo, including Barbers Point and Mililani — fulfills a second major milestone in a 2010 consent decree mandated by the federal government, designed to prevent untreated sewage from entering Oahu’s marine and shoreline environments.
