About Drain Field Repair in Reno
The drain field (also called a leach field or absorption field) is where your septic system's real work happens — liquid effluent percolates through gravel and soil, where bacteria break down remaining contaminants before the water reaches the groundwater table. When a drain field fails, untreated sewage can surface in your yard, contaminate nearby wells, and create a serious health hazard. Drain field failures happen for several reasons: biomat buildup (a thick bacterial layer that clogs the soil), root intrusion from nearby trees, vehicle traffic compacting the soil above the field, or simply reaching the end of the field's natural lifespan (typically 15-25 years). Repair options range from less invasive approaches — jetting distribution pipes, adding bacterial supplements, or installing a curtain drain to lower the water table — to full drain field replacement, which involves excavating the old field and installing new distribution trenches in virgin soil. Some states allow advanced remediation techniques like fracturing (injecting air into the soil to restore percolation) or adding a supplemental treatment unit upstream. Costs vary widely based on the repair method, field size, and local soil conditions.
What Reno Homeowners Should Know
Local Soil Conditions: Reno area soils include the Orr gravelly loamy sand and Reno fine sandy loam in the Truckee Meadows—deep, well-drained to somewhat excessively-drained desert soils with moderate to rapid permeability. Churchill loam and Fernley silt loam occupy lacustrine terrace positions with moderately slow permeability in the silty subsoil. Caliche (petrocalcic horizon) is present in older alluvial surfaces at depths of 20 to 48 inches. Sierra Nevada foothill soils include Gefo gravelly loam and Cagwin cobbly coarse sandy loam—shallow, rocky soils over granitic bedrock.
Water Table: Truckee Meadows floor areas along the Truckee River show seasonal groundwater at 4 to 12 feet during spring high flow. Reno upland areas and bench terraces show groundwater at 15 to 50 feet. Sierra Nevada foothill areas above the valley have deep groundwater at 30 to 100 feet.
Climate Impact: Reno has a semi-arid high-desert climate at 4,498 feet elevation, featuring over 300 days of sunshine annually. Annual precipitation averages 7.5 inches. Winters are cold with moderate frost. The Sierra Nevada creates a strong rain shadow effect. Summer afternoons are hot and dry, while spring brings occasional thunderstorm activity. Wildfire smoke is an increasing seasonal presence in the region.

The Drain Field Repair Process
- 1 Diagnose the failure type through inspection, probing, and camera work
- 2 Evaluate repair vs. replacement based on field age and failure severity
- 3 If repairable: jet distribution pipes, treat with bacteria, or install drainage

- 5 Excavate the failed field and install new distribution trenches
- 6 Connect to existing tank and distribution box, backfill and grade
