New Septic System Installation

New Septic System Installation in Spartanburg

A new onsite wastewater system is more than a tank in a hole. Donnymost designs and installs the complete system for your Spartanburg County property: a watertight concrete, polyethylene, or fiberglass tank, a distribution box that splits flow evenly, and a drainfield sized from your soil’s percolation rate. We size the tank from bedroom count, so a typical three bedroom home near 29306 gets a 1,000 gallon tank and a four bedroom home a 1,500 gallon unit.

Why the Soil Comes First

Piedmont red clay drains slowly, and the drainfield size is set entirely by how fast water moves through your ground. We run a perc test and read the full soil profile before we design anything, because a field sized for sand will surface within a year on tight Spartanburg clay. On lots with a high seasonal water table, we hold the four feet of vertical separation the South Carolina code requires, importing sand fill for an at-grade or mound bed when the native soil cannot.

Our Process

We start with the perc test and site evaluation, then submit the design to the Spartanburg County health department for a permit. Once approved, we excavate, set the tank level and watertight, lay the D-box and drainfield trenches (gravel or gravelless chambers over geotextile fabric), and backfill. We bring gasketed risers to grade so future pumping never means digging up the yard, and we leave you a clean as-built record for your operating permit.
