Drainfield and Leach Field Installation

Drainfield and Leach Field Installation in Bangor

The drainfield is where your septic system actually treats effluent, and it is usually the biggest cost variable on a Bangor install. Pinegenome builds the soil absorption area with gravel trenches or plastic leaching chambers, sized directly from your perc rate so treated water disperses through the soil instead of surfacing or backing up. Conventional trench and chamber fields typically run $5,000 to $15,000, and engineered mound systems for poor soil run higher.

Why the Perc Rate Rules the Design

Two lots a mile apart in Penobscot County can need very different fields. A sandy lot near the Penobscot River drains fast and takes a smaller trench. A tight clay lot toward Hermon drains slowly and needs a larger field, and a high water table near Veazie may force a chamber or mound design to keep four feet of separation to groundwater. The perc test settles it, which is why we test before we price.

Our Process

We run the perc test and soil profile, confirm the drainfield size the county will permit, and lay out the field to the required well and property setbacks. Then we excavate the trenches, set the distribution box for even flow across every lateral, place washed stone or chambers under geotextile fabric, and backfill to grade.
