Why Choose Our Drain Field Repair
Drain field repair is one of the most technically demanding services in the septic industry. Septiclear Inc has been serving Oregon homeowners since 2012, with hundreds of drain field repairs completed across Multnomah, Clackamas, Washington, Yamhill, Columbia, and Marion counties. Our qualified technicians bring hands-on experience in leach field diagnostics, soil testing, soil restoration, and full system rehabilitation.
We don’t guess. We inspect first. Using camera inspection and dye testing, we locate the exact source of failure – whether that’s a collapsed lateral line, a saturated gravel bed, or a blocked distribution box. That means you get a repair that actually solves the problem.
Our team handles everything from minor drain line repairs to full trench excavation, new drain field installation, and complete replacement. We work with gravity systems, pressure distribution systems, mound systems, and chamber systems. No drain field layout is outside our scope.
Septiclear Inc uses professional-grade bacterial treatment and enzyme treatment products that restore microbial activity in the soil absorption zone. Many clients avoid full replacement entirely with our remediation approach.
Our work is led by Ryan Lear, an Oregon DEQ-certified septic contractor. Our technicians are certified through the National Association of Wastewater Technicians (NAWT) and stay current on all Oregon DEQ and local health department wastewater regulations. We back every drain field repair with a 1-year workmanship warranty covering all lateral line replacements and excavation work. Our technicians are fully insured.

Signs You Need Drain Field Repair
Sewage odors near the leach field:
A strong odor of sewage or wastewater around your yard – especially near the drain field area – signals that effluent isn’t dispersing properly. This often means the soil is saturated, the biomat has thickened, or a lateral line has cracked or collapsed.
Slow drains and backed-up fixtures:
When toilets, sinks, and showers drain sluggishly throughout the house, the problem frequently originates in the drain field rather than your interior plumbing. Widespread plumbing issues across multiple fixtures are a strong indicator of drain field failure, not an isolated pipe blockage. A clogged or waterlogged leach field creates backpressure through the entire system, pushing sewage back toward the home.
Wet or soggy ground above the drain field:
Pooling water, spongy soil, or unusually green grass directly above your leach field trenches indicates that effluent is surfacing rather than absorbing. This is a clear sign of soil saturation, hydraulic overloading, or a failed gravel bed.
Sewage backing up into the home:
Active sewage backup through floor drains or toilets is a serious failure. It typically means the drain field is completely blocked or the distribution box has failed, forcing wastewater back through the system. This requires immediate drain field repair.
Failed percolation test results:
If a percolation test shows that your soil can no longer absorb water at an acceptable rate, your leach field has lost its infiltration capacity. This can result from compaction, biomat accumulation, or long-term hydraulic overloading – all conditions Septiclear Inc diagnoses and repairs.
Is It Time to Pump Your Tank?
Our Drain Field Repair Process
System Inspection and Diagnosis
We start with a full inspection of your septic system, including camera inspection of the lateral lines, probing of the drain field area, and a review of your tank’s inlet baffle, outlet baffle, and distribution box. We also check for sludge and scum levels that may be contributing to leach field failure.
Soil and Percolation Testing
Our technicians conduct soil testing and percolation tests to measure infiltration rates and identify compaction or saturation zones. Dye testing helps us map exactly where effluent is traveling – or failing to travel.
Repair Plan and Permitting
Based on our findings, we develop a targeted repair plan. This may include biomat remediation, lateral line replacement, gravel bed restoration, or full trench excavation. We pull all required permits before work begins.
Excavation and Repair
Our crew performs precise trenching, removes failed materials, installs new perforated pipe or chamber components, and restores the gravel bed. We apply bacterial treatment or enzyme treatment to the soil absorption zone as needed.
Backfilling, Grading, and Final Inspection
We backfill and compact the repair area, grade and slope the surface correctly, and conduct a final inspection to confirm the system is dispersing effluent properly. We document all work completed.
Never Miss a Pump Date Again
We offer annual and biannual scheduled pumping plans for residential and commercial customers – set it once, stay consistently maintained.
Brands We Use
Septiclear Inc uses trusted, professional-grade products and equipment for every drain field repair. These brands meet industry standards for wastewater treatment, soil remediation, and system restoration.
We never apply treatments that could contaminate groundwater or wetlands near your property.

FAQs About Drain Field Repair
What is drain field repair?
Drain field repair is the process of diagnosing and fixing a failed or malfunctioning leach field – the underground network of perforated pipes, gravel beds, and soil absorption zones that treat and disperse effluent from your septic tank. Repairs range from biomat remediation and pipe replacement to full trench excavation and system rehabilitation.
When do I need drain field repair?
You need drain field repair when you notice sewage odors in your yard, slow drains throughout the house, soggy ground above the leach field, sewage backup inside the home, or a failed percolation test. Routine maintenance of your septic systems can help catch these issues before they escalate into costly failures. The sooner you act, the more repair options you have.
Why is my drain field failing?
Drain fields fail for several reasons. Biomat buildup from anaerobic decomposition blocks soil infiltration. Hydraulic overloading saturates the soil. Soil compaction from vehicles, heavy equipment, or a recent landscaping project crushes lateral lines and restricts drainage. Tree root intrusion is another frequent cause – tree root growth can crack, offset, or completely block perforated pipes over time. Age and deterioration break down perforated pipe and gravel beds as well.
How does drain field repair work?
Septiclear Inc inspects the system using camera inspection, probing, and soil testing. We identify the failure point, develop a repair plan, pull permits, and perform the necessary work – whether that’s bacterial treatment, pipe replacement, or full excavation and reinstallation.
Can a drain field be repaired without full replacement?
Yes, in many cases. Biomat remediation using bacterial treatment and enzyme treatment can restore soil absorption capacity without excavation. For more severe failures, a complete replacement with new drain field installation may be required. The cost of repair versus complete replacement depends on the extent of the damage, which is why a proper diagnosis always comes first.
Does drain field repair require a permit?
In most jurisdictions, yes. Any excavation, pipe replacement, or system modification requires a permit from your local health department. Septiclear Inc handles all permitting as part of the repair process.
