Cesspool to Septic Conversion in Keaau, 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 Keaau

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 Keaau

Keaau is the gateway to Puna, the town at the junction where Highway 11 climbs toward Volcano and Highway 130 drops toward Pahoa, and the place every Puna homeowner passes on the way to Hilo. The old plantation town center around Old Volcano Road and Keaau Village has a mix of camp-era houses and newer homes, the Shipman industrial park sits on the Hilo side, and the big subdivisions start right at the edge of town: Hawaiian Paradise Park makai, Orchidland and Ainaloa mauka and south. Keaau itself is largely unsewered; the older houses are on cesspools and the newer builds and the conversions are on septic. The land is young lava with a thin skin of soil in places and bare pahoehoe in others, and the rain is heavy enough that a cesspool near the bottom of a lot can take on groundwater after a storm. Because it is the hub, Keaau also sees a steady flow of first-time Big Island buyers who have never owned a cesspool and want to understand what they are getting into. We pump, inspect, convert and repair systems in and around Keaau every week. Tell us the street and what the system is doing, and we will give you an honest answer and a price before the truck rolls.

Common Cesspool & Septic Issues in Keaau

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

Camp-era cesspools in the old town

The plantation houses around Old Volcano Road and Keaau Village sit on cesspools that are often older than their owners. Decades of sludge seal the rock and the pit holds more each year. A thorough pump-out, with the walls and refill rate checked, tells you whether it has years left or is near the end.

New owners who have never had a cesspool

Keaau is where a lot of mainland buyers land first. They know septic; they have never heard of a cesspool. We explain what is in the yard, how often it needs pumping, how close it sits to the catchment tank, and what the state deadline means for this house, in plain words.

Groundwater in low pits after storms

On the lower, flatter lots around Keaau a cesspool can fill from the surrounding rock during a long wet spell, not just from the house. If yours backs up only when it rains, that is what is happening. Pumping gets you through the storm, and we will tell you honestly whether the pit is still viable.

Cesspool Conversion in Keaau: FAQs

Do you serve the Keaau area and the subdivisions around it?
Yes. Keaau is the center of our Puna work: the old town, Shipman, Ainaloa and the agricultural lots, and the subdivisions that start at the edge of town, Hawaiian Paradise Park, Orchidland and Hawaiian Acres. Tell us the subdivision and the road and we will come prepared.
I just bought a house in Keaau and have no idea where the cesspool is. Can you find it?
Yes. Buried lids and capped pipes are the norm on older Puna homes. We locate the pit from the plumbing exit and the lot layout, open it, pump it, and mark the location so the next service is quick.
Does my Keaau cesspool have to be converted before I sell?
In most sales today, no. The Department of Health sets the rules, and the cesspool can usually transfer with the house and its deadline moves to the new owner. Buyers and lenders sometimes ask for a conversion or a credit anyway, so a clear inspection report helps both sides settle it.
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.
