Cesspool to Septic Conversion in Mountain View, 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 Mountain View

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 Mountain View

Mountain View is the upper Puna village on Highway 11 at about 1,500 feet, where the rainforest closes in, the air turns cool, and the subdivisions behind it, Fern Acres, Fern Forest, Eden Roc and the upper reaches of Hawaiian Acres, stretch back into some of the wettest country on the island. The village has its old plantation core and a scattering of farms and nurseries along the highway, and nearly everything is on catchment and on its own wastewater system. This is where the rain is heaviest in our whole service area, in places well past 150 inches a year, and wastewater here lives with that. Cesspools sit in rock that is wet nearly all the time, fern forest holds water on the surface for days after a storm, and a pit that is also full of sludge has no margin at all. The subdivisions behind Mountain View also hold a lot of part-time, off-grid and newly arrived owners, on long unpaved roads, with systems that came with no paperwork. We pump, inspect, convert and repair systems in Mountain View and the subdivisions behind it, and we know what the roads are like after a week of rain. Tell us where you are and what the system is doing, and we will come ready and quote it straight.

Common Cesspool & Septic Issues in Mountain View

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

The wettest ground we work in

Mountain View and the subdivisions behind it see some of the heaviest rain on the island, and the fern forest floor holds it. Cesspools here refill from the ground and stay wet year-round. Regular pumping keeps a buffer in the pit; a pit that has stopped draining will show it in the refill rate, and we will tell you.

Off-grid homes on long unpaved roads

Fern Acres, Fern Forest and Eden Roc have homes a mile or more back on cinder roads that soften after rain. We ask about the road when you call, bring enough hose to park on solid ground, and reach the pit from there.

Systems with no history

A lot of upper Puna homes sold with a cesspool and no paperwork. We locate it, pump it, read the walls and the refill, and give the new owner a straight picture of its condition and what the state deadline means for it.

Cesspool Conversion in Mountain View: FAQs

Do you serve Fern Acres, Fern Forest and Eden Roc as well as Mountain View village?
Yes. The subdivisions behind Mountain View are part of our regular upper Puna route. Tell us the road and how far back the lot sits, and whether the road has been soft lately, so the truck comes ready.
Why does my cesspool stay full even when it has not rained for a few days?
At this elevation the ground rarely dries out, and the rock around the pit holds water for a long time after a storm. The pit refills from the ground. It can still work as long as there is room for the household, but the sludge has to be pumped regularly and the pit’s drainage checked.
Can a septic system be built in rainforest ground like this?
Yes. A conversion here is a raised leach bed on imported fill, sized for the rainfall as well as the house, or an aerobic treatment unit where the lot or the ground calls for it. The design accounts for the wet ground and the catchment setbacks, and the Department of Health reviews 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.
