Hawaiʻi Act 125 · Cesspool Mandate

Plan ahead. Don’t wait.

Hawaiʻi Act 125 (HRS 342D-72) requires every cesspool in the state to be upgraded, converted, or connected to sewer by January 1, 2050. The Hawaiʻi Department of Health also publishes planning-urgency categories so homeowners and agencies can decide where to convert first.

Plan First
Priority 1

DOH planning urgency (not a legal deadline). Typically cesspools near shorelines, streams, and drinking-water sources.

Plan Early
Priority 2

DOH planning urgency (not a legal deadline). Typically high-density and environmentally sensitive areas.

2050
Statewide Deadline

The only enacted statewide deadline under Act 125. All cesspools must be upgraded, converted, or connected to sewer by January 1, 2050.

“They set clear expectations from the beginning, handled the paperwork professionally, and once approvals were in place, the crew was in and out in days. They left our yard cleaner than they found it.”
