Alternative System Conversions
Upgrade failing seepage pits to modern drain field systems when soil conditions or regulations require more advanced treatment technology.

How Seepage Pit Repair Saves You Time and Money
Professional seepage pit repair restores performance, prevents contamination, and saves thousands compared to full system replacement.
Restore Waste Processing Capacity
Working seepage pits eliminate backups by providing adequate soil absorption for your household’s septic system output.
Avoid Expensive System Replacement
Strategic repairs often restore pit function at much lower cost than installing completely new septic absorption systems.
Prevent Environmental Violations
Properly functioning seepage pits keep effluent underground, avoiding surface contamination that triggers health department enforcement actions.
Maintain Property Accessibility Fully
Fixed pits eliminate soggy areas and odors that make portions of your yard unusable for normal activities.
Extend Overall System Life
Healthy seepage pits reduce stress on your septic tank and distribution components, helping everything work better longer.
