County of Kaua‘i Residential Cesspool Conversion Grant Program

The County of Kaua‘i Residential Cesspool Conversion Grant Program offers financial assistance to homeowners seeking to upgrade their existing cesspools to approved individual wastewater systems (IWS). This program aims to support environmental health by reducing pollution from outdated cesspools. Selected applicants may receive up to $20,000 to help cover the costs of these necessary upgrades. To be eligible, applicants must be homeowners on Kaua‘i with an existing cesspool that requires conversion. The new wastewater system must be approved by the Hawai‘i State Department of Health-Wastewater Branch. The program is funded through the Hawai‘i State DOH Water Pollution Control Revolving Fund, with a total allocation of $2 million available to support approximately 100 homeowners. Applicants need to provide several documents as part of their application. These include a building permit application number if applicable, recent federal tax returns for all income-earning household members, and certification from a licensed Hawaii civil engineer confirming the cesspool is failing or evidence such as invoices related to cesspool pumping or spills. If someone other than the homeowner applies, proof of legal representation is required. The grant covers reimbursement for costs associated with upgrading the wastewater system and does not specify a duration for use beyond the application deadline. Applications are currently being accepted until September 27, 2024. Homeowners interested in improving their property’s wastewater management while contributing to local environmental efforts are encouraged to apply. More detailed information and application instructions are available on the County of Kaua‘i website. This grant provides an opportunity for homeowners on Kaua‘i to access funding that supports compliance with state health standards and promotes safer water quality in their communities.
