Drainfield Repair

All conventional septic systems have a finite life. Even properly used, drainfield rock eventually becomes plugged with the by-products of treating sewage. Septic systems that are used properly will still eventually fail. Replacement costs run from $7,200 to $20,000 or more in some areas.


Why systems fail

A properly operating drainfield or mound treats sewage by providing an environment for soil organisms to clean the waste. Oxygen must be present in the system for this to occur.

As systems age, a clogging mat forms where the rock and soil meet. This biomat is comprised of dead bacteria, fine solids, and live soil bacteria. It performs a vital function by holding water in the rock long enough to prevent saturation of soil below the rock.

Over time this clogging mat gets too thick, however, and causes water to pond in the rock. Air is displaced by liquid and anaerobic conditions begin the decline of the soil treatment system.

Even if properly designed and constructed, conventional septic systems eventually need replacement or rehabilitation. Homeowners using them within design limits can expect drainfield or mound life of 7-25 years.

We offer system saving recovery solutions that can provide an immediate fix to your septic system and avoid replacement cost.  Our service areas in Minnesota include Milaca, Princeton, Zimmerman, Isle, Onamia, Aitkin, Wahkon, Garrison, and surrounding areas.  Contact us for a free site visit and estimate.

Recovery options

Terralift Drainfield Rejuvenation:  New life for your problem drainfield or mound in one day without excavating your lawn. The Terralift process injects high pressure blasts of air into the ground to fracture soil and re-establish percolation.  In addition, it stirs up excess biomat which is then digested.  It provides an immediate fix to ponded and surfacing drainfields.


  • Immediate relief
  • Re-establish percolation
  • No excavation required
  • Fix your drainfield while waiting for sewer connection
  • Five year prorated warranty

Aerobic Treatment: 
 Adding aerobic treatment to your septic system converts anaerobic (low oxygen) effluent to aerobic (high oxygen) effluent.  Aerobic bacteria are much more active than anaerobic bacteria and can consume 75 to 90 % of the material in the waste stream.  As this oxygenated effluent flows into the drainfield the aerobic bacteria begin to digest excess biomat and eventually restore percolation into the soil.  Systems may recover in one to six months at a fraction of the cost of replacement.


  • Reduces the biomat layer clogging your drainfield
  • Extends the life of your system
  • Fix your drainfield while waiting for sewer connection
  • Money back guarantee

Bio remediation:
  Adding bacteria to your system periodically can help avoid premature failure if a healthy bacteria population does not already exist.  A large initial dose can help restore function to a failing system.
View our bacterial treatment options.

Benefits:  Ensure a large population of beneficial bacteria in your system to assure optimal treatment.

Repair options

Eliminate water infiltration:  Repair leaks that may allow groundwater to overload your drainfield.
Benefits:  In some cases eliminating infiltration is sufficient to recover a failed drainfield.

Freezing prevention:  Insulate components or add a heat source to your tank. Repair sagging pipes.
Benefits:  No costly winter service visits, or broken parts.

Add timed dosing:  Even out high water flows to prevent overloading of your drainfield.

Line cleaning:  Remove clogging debris from pipes

Regular maintenance visits:  Insure proper operation.
