HI HB1806

Requires all cesspools in Hawaii to be upgraded or converted to a director-approved wastewater system, or connected to a sewerage system, before January 1, 2050

Permits the Director of Health to grant exemptions to property owners who demonstrate legitimate infeasibility, including small lot size, steep topography, poor soils, or accessibility issues

Replaces specific references to "septic system" and "aerobic treatment unit system" with broader term "director-approved wastewater system" to allow flexibility in conversion methods

Defines "cesspool" as an excavated individual wastewater system that retains organic matter and solids while allowing liquid to seep through bottom or sides into underground formations

Takes effect upon approval
