Percolation Testing

Percolation Testing or sometimes referred to as a Perc Test, Perk test, Percolation Investigation, Feasibility Test, Septic System Test, etc. is performed to determine the feasibility of using an on-site wastewater treatment system on the lot or parcel in question. Perc Tests are generally performed for either a leach line or seepage pit application but are also performed for Advanced Treatment System approval. For lots requiring septic, a passing Percolation test is required by the lender to close escrow on a real estate transaction. Percolation tests (Perk Tests) are required and performed for several reasons such as:

• Purchase or sale of vacant land
• Preparation of building permits
• Additions to existing homes
• Additional dwelling unit permits (ADU)
• Commercial and Residential Construction
• Repair or replacement septic systems

Perc Tests are performed by digging several percolation test holes and logging how fast water poured into these perc test holes dissipates thereby simulating an onsite wastewater treatment system. An exploratory bore hole (usually 15' - 50' deep) is also part of a perc test and is used to assess the possibility of groundwater which could cause a failed perk test. The Results from the percolation test will read in minutes per inch and will establish how big or small your septic system needs to be to function properly.
