Cesspool to Septic Conversion in Hawaiian Paradise Park, 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 Hawaiian Paradise Park

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 Hawaiian Paradise Park

Hawaiian Paradise Park, HPP to everyone who lives there, is one of the largest subdivisions in the state: a grid of one-acre lots running from Highway 130 down to the sea cliffs at Kaloli Point, with Paradise Drive, Makuu Drive and Kaloli Drive as its spines and dozens of numbered avenues between them. The roads are private and maintained by the owners’ association, nearly every house is on rainwater catchment, and nearly every house is on its own wastewater system: cesspools on the older homes, septic systems on the newer builds and the conversions. The land is flat pahoehoe and a‘a with little soil, and the lower avenues near the coast sit close enough to sea level that a cesspool there can take on groundwater and fill from below. HPP has grown fast with mainland buyers drawn to an acre of land near Hilo, which means a steady run of home sales, each wanting a pump-out and an inspection, and a lot of new owners who are learning what a cesspool is and what the state deadline means for it. We pump, inspect, convert and repair systems up and down the avenues every week. Tell us the avenue and the cross street and what the system is doing, and we will quote it straight.

Common Cesspool & Septic Issues in Hawaiian Paradise Park

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

Groundwater in the lower avenues

Below Paradise Drive the lots get closer to sea level and the rock holds water. A cesspool there can refill from the ground, not just the house, and backs up after storms. We watch the refill rate during a pump-out and tell you honestly whether the pit is viable or whether conversion is the real fix.

Conversions on one-acre lava lots

An acre sounds like plenty of room until you place the house, the driveway, the catchment tank and the required setbacks. Most HPP conversions mean a raised leach bed on imported fill over the pahoehoe, or an aerobic unit on the tighter layouts. We walk the lot first and quote the system that actually fits.

Fast turnover and new owners

HPP changes hands constantly, and buyers from the mainland have usually never owned a cesspool. We inspect for closings, explain what is in the yard, and put the new owner on a pumping schedule that matches the household instead of a guess.

Cesspool Conversion in Hawaiian Paradise Park: FAQs

Do you service all of Hawaiian Paradise Park, including the lower avenues?
Yes, from the upper avenues by Highway 130 down to Beach Road and Kaloli Point. HPP’s private roads and long gravel driveways are routine for us. Tell us the avenue and the nearest cross street so the driver finds you quickly.
How much room does a cesspool-to-septic conversion need on an HPP lot?
Less than people fear, more than it looks. The tank and the leach bed or aerobic unit have to sit set distances from the house, the catchment tank, the property lines and any neighbor’s catchment. On most one-acre lots a conventional system fits; on tighter layouts an aerobic unit needs less ground. We lay it out on site and quote accordingly.
I have a catchment tank near the cesspool. Is that a problem?
It can be, and it is something a home-sale inspector will note. We keep our hoses and any spill well away from the tank during pumping, and if the setback is tight we will say so and explain what a conversion would do about 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.
