Hawai'i Cesspool Law
Do You Need to Convert Your Cesspool?
Hawaii state law requires most cesspools to be upgraded or converted to septic systems, and the deadline affects thousands of O'ahu homeowners. If you're not sure where your property stands, Alpha Omega can inspect your system, walk you through the requirements, and handle the conversion from start to finish.
