Maui Cesspool Help
Independent referral service — not a contractor. How we work & get paid

The conversion process, step by step

Based on the Department of Health steps summarized by Wastewater Alternatives & Innovations (waicleanwater.org):

  1. Hire a Hawai‘i-licensed civil engineer to evaluate the site (including a percolation test) and design the system.
  2. Engineer submits plans to DOH Wastewater Branch for review. One Maui installer reports this usually takes about 4–6 weeks.
  3. Hire a licensed contractor holding an A, C-9, C-37, C-37a, or C-43 license. Verify the license with DCCA’s license search.
  4. Construction — one Maui installer reports about two working weeks on average, longer with rock or larger systems. The old cesspool is pumped, demolished and backfilled.
  5. Final inspection and approval — the engineer submits the final report and contractor certification; DOH issues an Approval to Use.

Some contractors handle engineering and permitting as a turnkey package; others ask you to bring approved plans. Our form asks which situation you’re in.
