Cesspool to Septic Conversion in Kawaihae, HI

Replace a failing or soon-to-be-closed cesspool with a septic system sized for your lot, with the permit, the rock work, and the closure handled.

Cesspool Conversion in Kawaihae

Converting a cesspool means taking the pit out of service and putting in a real treatment system: a septic tank with a leach field or seepage pit, or an aerobic treatment unit where the lot is small or the rock is tight. The state has stopped permitting new cesspools and set a deadline for existing ones to be converted or closed, so every cesspool on the Kona side is going to need this work eventually, and a failing one needs it now. We handle cesspool-to-septic conversions across West Hawaii from the first site visit to the last inspection: we evaluate the lot and the rock, work out which system type fits, handle the state wastewater permit, excavate in lava, set the tank and field, connect the house, and pump and properly close the old cesspool. We quote the whole job up front, including the rock work, so the number you plan around is the number you pay.

Cesspool & septic service in Kawaihae

Kawaihae is the harbor town at the north end of the Kohala coast, hot, dry, and small, with the commercial harbor, Puukohola Heiau, and Spencer Beach Park at the water and the big ranch-style estates of Kohala Ranch, Kohala Estates, and Kohala Waterfront climbing the slope above it toward Kohala Mountain Road. There is no county sewer out here. The homes near the harbor are older and sit on cesspools and septic tanks set into hard dry a‘a lava; the estates upslope are newer and larger, often on septic systems or aerobic units sized for big houses and guest quarters, with long private driveways and gated access. We pump cesspools and septic tanks, convert cesspools to septic, inspect for home sales, and repair failed systems throughout Kawaihae and the Kohala estates. This is the far north edge of what we cover, and the practical point is that fewer crews come this way, so scheduling and a crew that actually shows up matter. We see pits sealing in dense dry lava, aerobic units on large homes that nobody has serviced since the install, second homes that sit empty between visits, and sales where an off-island buyer needs a written inspection before closing. Tell us where the property is and what the system is doing, and we will give you a straight answer and a real time.

Common Cesspool & Septic Issues in Kawaihae

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

Large estates on aerobic units nobody has serviced

The big homes in Kohala Ranch and the surrounding estates often run on aerobic treatment units sized for a main house and guest quarters, with pumps, aerators, and alarms that need periodic attention. Many have not been looked at since the install. We test and service them and get them on a schedule before an alarm goes off with a house full of guests.

Pits in hard, dry a‘a lava

The older homes near the harbor sit on cesspools and seepage pits set into some of the driest, hardest rock on the island. A pit that landed in dense lava was marginal from the start, and once its walls coat over it stops taking water. We read how the system is draining while it is open and tell you whether pumping buys time or a conversion is the honest answer.

The far north edge, where crews are scarce

Kawaihae and the Kohala estates are a long way from Kona, and fewer wastewater crews come this far. We make the drive, group calls where we can so you get a real time window, and bring the hose length for gated estates with long private driveways.

Cesspool Conversion in Kawaihae: FAQs

Do you cover Kawaihae and Kohala Ranch?
Yes. We cover the harbor area, Kohala Ranch, Kohala Estates, Kohala Waterfront, and the Mauna Kea resort side. It is the north edge of our range, so we schedule carefully and give you a real time. Tell us about the gate and the driveway and we will come prepared.
Our estate has an aerobic system with an alarm. What does it need?
Periodic service: the pump, aerator, floats, and alarm need to be tested and the tank pumped on schedule. If the alarm sounds, it usually means the pump tank is filling faster than it empties or the aerator has stopped. Cut back on water and call; we test and replace what is worn and get it back on a maintenance plan.
We only use our Kohala home part of the year. How should we manage the system?
Have it pumped on a schedule that matches how heavily it is used when occupied, and the aerobic components checked before each busy season. We can locate the system, set an interval, and look at it before you arrive so you are not dealing with a backup during a visit.
Do I have to convert my cesspool?
The state has set a deadline for all cesspools to be converted or closed, so eventually, yes. You do not have to do it this year unless the pit is failing or a sale requires it. We can tell you how much life your cesspool has left and lay out the conversion so you can plan the timing.
What will a conversion cost on my lot?
It depends mostly on the rock, the system type, and access. A simple septic tank and seepage pit in porous lava with good truck access is the low end; an aerobic unit on a tight lot in dense rock is the high end. We give a real number after a site visit, not a range off the phone, and the quote covers the whole job.
Septic tank or aerobic unit, which should I get?
A conventional septic tank with a leach field or seepage pit is simpler, cheaper to run, and right for most lots with room and workable rock. An aerobic unit treats to a higher standard in a smaller footprint but has a pump, an aerator, and an alarm that need power and maintenance. We recommend based on your lot, not on what is easiest for us.
How long does a conversion take?
The permit is usually the long part. Once it is in hand, the excavation and installation on a typical Kona lot run from a few days to about two weeks depending on the rock. We sequence it so the house stays usable, and the old cesspool is closed as the last step.
