Hawai‘i Sea Grant Cesspool Resources 

Welcome to the University of Hawai’i Sea Grant College Program Cesspools Homepage! Hawai’i has over 83,000 cesspools that excrete approximately 52 million gallons of untreated wastewater every day. This portal features a number of products focused on the environmental and human health impacts of cesspools and the need for their statewide conversion to more advanced forms of wastewater treatment.
