Kamehameha Schools will audit more than 3,000 properties statewide to identify and close large-capacity cesspools under an agreement with the U.S. Environmental Protection Agency that also calls for Hawaii’s largest private landowner to pay nearly $100,000 related to a large cesspool on the Big Island.
Large-capacity cesspools were banned by the federal government in 2005 and the state of Hawaii is working to close or upgrade all small-capacity cesspools by 2050.
