Cesspool to Septic Conversion in Honomu, HI

Replacing a cesspool with a permitted septic system, designed for your lava-rock lot and the state deadline. A straight walkthrough of options and cost before anything is dug.

Cesspool Conversion in Honomu

Hawaii has set a deadline for every cesspool in the state to be converted or closed, and nowhere does that land harder than East Hawaii, where whole subdivisions were built on cesspools drilled into the lava. A conversion means closing the pit and installing a permitted individual wastewater system in its place: typically a septic tank with a leach field or seepage bed, or an aerobic treatment unit where the lot is too small or too wet for a conventional field. We handle cesspool-to-septic conversions across Hilo, Puna and the Hamakua coast, from the site evaluation and the design that the Department of Health requires through the excavation, the tank and field installation, and the final inspection. Lava changes everything about this work. There is little or no soil, so most fields here are built on imported fill, and a lot that looks flat and easy may sit on a lava tube or on pahoehoe that will not break without a hammer. We look at your lot first, tell you which system actually fits it, and give you a real number before anything is dug.

Cesspool and septic service in Honomu

Honomu is the little plantation town at the turnoff to Akaka Falls, a single main street of raised wooden storefronts just off Highway 19 about ten miles north of Hilo, with camp houses behind it, Hakalau and its bay a few minutes north, and the road to the falls climbing mauka through old cane land and gulches. The town is unsewered and so is everything around it. The old houses on the main street and the camp lots are on cesspools from the sugar days; the farm parcels and newer homes up the Akaka Falls road and toward Hakalau are a mix of cesspools and septic, and the conversions are adding to the septic side every year. The ground is Hamakua ground, real soil over old lava, cut by deep gulches that carry serious water in a storm, and the rain here is heavy and steady through the winter. Honomu is small enough that the pump truck is a familiar sight, and the mix of long-time families, visitors passing through to the falls, and newcomers restoring a plantation house keeps us busy with pump-outs, inspections for the houses that change hands, and conversions planned ahead of the state deadline. We work Honomu, Hakalau and the Akaka Falls road regularly. Tell us where you are and what the system is doing, and we will quote it straight.

Common Cesspool & Septic Issues in Honomu

The cesspool and septic problems we see most around here, and how we handle them.

Plantation storefronts and camp houses on old pits

Honomu’s wooden buildings and camp houses sit on cesspools that predate most of their owners. They are often shallow and often unmarked. We locate, open and pump them, read the walls and the refill, and tell you how much life the pit has.

Gulches and storm runoff

The gulches around Honomu move a lot of water in a storm, and a cesspool or a leach field in their path takes on runoff it was never designed for. Diverting surface water and keeping the pit pumped is the defense against a wet-winter backup.

Restored plantation homes changing hands

Honomu draws buyers who want to restore a plantation house, and they inherit its cesspool. We inspect for closings, explain what the pit is doing and what the state deadline means, and lay out the conversion options for a small town lot.

Cesspool Conversion in Honomu: FAQs

Do you serve Honomu, Hakalau and the Akaka Falls road?
Yes. Honomu is a regular stop on our Hamakua route and we cover the main street, the camp lots, the road up to the falls and Hakalau. Tell us where you are and how the access sits and we will come prepared.
I bought a plantation house in Honomu. What should I do about the cesspool first?
Have it located, pumped and inspected so you know what you have. A pit that has not been opened in decades is full of sludge and may be near the end of its life, or it may have years left. The inspection tells you which, and what a conversion would involve on your lot.
Can a cesspool on a small Honomu town lot be converted?
Almost always. If a conventional leach field will not meet the setbacks, an aerobic treatment unit needs less ground. We walk the lot, confirm what the Department of Health will approve, and give you a written price.
Do I have to convert my cesspool now?
For most homes, not yet. The state has set a deadline for every cesspool to be converted or closed, and the Department of Health controls the schedule and the exceptions. What forces the issue sooner is a cesspool that has stopped draining, a sale where the buyer or lender wants it done, or a remodel that triggers a permit review. We can tell you which of those applies to you.
What does a conversion cost in Puna or Hilo?
It depends on the lot more than anything: how hard the rock is, whether a conventional field will fit, how far the truck and excavator can get in, and which system the Department of Health will approve. We give a written price after walking the lot, not a phone estimate that grows later, and we are up front that an aerobic unit or a raised bed on fill costs more than a simple tank and field.
Can I keep using my cesspool while the septic system is built?
Usually, yes. The new tank and field go in beside the old pit, the house plumbing is switched over once the new system is inspected, and then the cesspool is pumped, closed and filled. Most conversions keep the household running throughout, with a short switchover.
Will the conversion work with my rainwater catchment?
Yes, and the design has to account for it. The field or unit must sit a set distance from the catchment tank and from any neighbor’s, which on a smaller lot narrows where the system can go. We lay it out with the catchment in mind from the start so the permit is clean and your water stays clean.
