New    Tax Credit Program and Qualifying Cesspools   

Learn about the income tax credit for qualifying cesspools covered under Act 120. The list of cesspools based on tax map key that may qualify for the tax credit are also posted here.

New    Cesspools in Hawai’i   

Cesspools are substandard systems. They don’t treat wastewater, they merely dispose of it. Cesspools concentrate the wastewater in one location, often deep within the ground and in direct contact with groundwater, causing groundwater contamination. This groundwater flows into drinking water wells, streams and the ocean, harming public health and the environment, including beaches and coral reefs.

New   Public Hearings for Chapter 11-62 Hawaii Administrative Rules Amendments

The Department of Health (DOH) will receive written comments and hold public hearings on proposed changes to Hawaii Administrative Rules (HAR), Chapter 11-62, Wastewater Systems. Proposed changes include prohibiting the installation of new cesspools and implementation of Act 120 which provides a temporary tax credit for upgrading qualifying cesspools to septic systems or connecting to a sewer system of qualifying cesspools.
