A typical gravity septic installation

House Two-compartment tank Distribution box Drainfield trenches Native soil, undisturbed

A gravity install, in section. Fall, tank sizing, trench depth and the soil below the trench are what decide whether a system lasts thirty years or fails in five.

Septic installation

WOSA certified installer. We put in new systems, replace failed ones, and handle the excavation, tank set, drainfield and final grade as one job rather than four.

Sewer and utility connections

If the ground has to be opened for it, we can do it — new construction, remodels, or tying an existing house into service.
