It is the time, in minutes, for water in a test hole to drop one inch. It is used to size the drain field.
Requirements vary by jurisdiction. Many require a witnessed test; we schedule accordingly.
A failed test does not always mean a site cannot be developed. Alternative systems such as raised mounds may be permitted. We review the options with you.
Residential · 1,250-gallon plastic tank and stone leach field
Set a new 1,250-gallon two-compartment plastic septic tank and built a stone leach field with perforated laterals fed from a distribution box. After inspection, the site was backfilled, graded, seeded and mulched with straw, with silt fence installed for erosion control.
Residential · New plastic tank with risers and PVC line
Installed a new plastic septic tank with grade-level risers and laid a new PVC line bedded in sand, working close to the home's foundation. The site was then brought to final grade with silt fence in place for erosion control.
