Drain Field Repair

Drain field repair addresses problems with the leach field — the network of perforated pipes and gravel-filled trenches where liquid from your septic tank disperses into the soil for final treatment. When the drain field fails, wastewater can't absorb properly, leading to soggy ground, odors, and backups into the home. Repairing it restores the soil's ability to accept and filter effluent.

Drain fields fail for several reasons: a biomat of solids clogging the soil from years of overloading or missed pumpings, compaction from vehicles or construction, invading tree roots, or simple old age. Repairs range from relatively minor fixes like jetting the lines, replacing a distribution box, or fracturing compacted soil, all the way up to installing new trenches or a complete drain field replacement.

Because drain field problems are often the most expensive part of a septic system to fix, an accurate diagnosis matters. A skilled contractor will determine whether the field can be rehabilitated or must be replaced, and will design any new field to meet local code and soil conditions.

Straight from someone who's seen it all (and smelled most of it): half the failed fields I dig up were killed by something avoidable, like a truck parked on top compacting the soil or years of skipped pumpings clogging it with a biomat. Keep the weight and the roots off it and it'll outlast your mortgage. Treat your drain field like my back — don't park the truck on it.
