Septic System Installation & Repair in Hilo, HI

Installation & Repair in Hilo

New construction in East Hawaii goes in on a septic system, not a cesspool, and plenty of the systems already in the ground are reaching the age where parts fail. We install and repair septic systems across Hilo, Puna and the Hamakua coast. On the installation side we handle new homes and ohana units, the rebuilds that followed the 2018 eruption in lower Puna, and replacement systems for homes whose old cesspool or field has given out: the site evaluation, the Department of Health permit, the excavation in lava, the tank, the leach field or seepage bed on imported fill, and the inspection. On the repair side we fix what actually breaks: cracked lids and collapsed baffles, sewer lines crushed by rock settlement or invaded by roots, distribution boxes that send everything to one line, failed effluent pumps on lots that lift uphill, and leach fields that have gone wet. We find the real problem before we dig, because excavating lava to fix the wrong thing is an expensive mistake.

Cesspool and septic service in Hilo

Hilo is the county seat and the working heart of East Hawaii, wrapped around Hilo Bay between the Wailuku River and Keaukaha, with the whole Puna and Hamakua service area fanning out from its highways. Downtown, the Bayfront and the older grid around Waiakea are on county sewer, but step uphill into Kaumana, Ainako and the upper Waiakea Uka subdivisions, or out along the Puna side past Panaewa, and most homes are on a cesspool or a septic system of their own. Hilo is one of the wettest cities in the country, and that is the story of wastewater here: the ground is already full for weeks at a time, so a cesspool that drains fine in a dry stretch backs up after three days of rain, and a septic field on the Kaumana slope has to be built to shed water it did not ask for. Add the plantation-era houses with cesspools nobody has opened in decades, the student rentals near the university, the vacation rentals that fill up for Merrie Monarch week, and the steady run of home sales that each want a pump-out and an inspection, and there is plenty to do. We are based here and we work every part of town, from the bay up to the 2,000-foot line. Tell us the street and what the system is doing and you will get a straight answer and a real price.
