DFW Septic Service

Drain Field Repair & Replacement

A failing drain field — also called the leach field or absorption field — is the most expensive part of a septic system to fix. We diagnose honestly: if your field can be saved with jetting, aeration, or distribution box repair, we do that first. Replacement is the last option, not the default quote.

What's Included

  • Hydro-jet lateral lines
  • Soil aeration & fracturing
  • Distribution box repair & replacement
  • Bio-additive shock treatment
  • Saturated field diagnostics
  • Full conventional drain field replacement
  • Aerobic conversion for tight lots
  • County permits & inspections handled

Restoration before replacement

Many drain fields look failed but aren't. Solids that escaped a poorly maintained tank can clog the perforated pipes — jetting often restores 70–90% of flow capacity. Soil aeration fractures compacted clay and reintroduces oxygen to revive the bacterial colony. We always quote restoration before suggesting replacement.

Frequently Asked Questions

Can a failing drain field be saved without replacement?+

Sometimes. Mild cases respond well to hydro-jetting, soil aeration, and bio-additive treatment ($1,200–$2,800). Severe cases with collapsed lines or biologically dead soil usually require replacement.

How much does a new drain field cost in DFW?+

Full drain field replacement runs $5,000–$15,000+ depending on size, soil type, and county permit requirements. Aerobic conversions may be cheaper on tight lots.

How long does a drain field last?+

A properly maintained conventional drain field lasts 20–30 years. Lack of pumping is the #1 cause of premature failure.

What are the signs of drain field failure?+

Soggy ground when it hasn't rained, lush green stripes, sewage smell in the yard, slow drains that don't improve after pumping, and effluent surfacing.

Do I need a permit to replace my drain field?+

Yes — every DFW county requires an OSSF permit for drain field replacement. We pull the permit and coordinate the final inspection.
