Frequently Asked Questions
What is a perc test and why do I need one in California?
A perc test (percolation test) measures how quickly water drains through soil. It is required before installing any new septic system and is conducted under the oversight of your local board of health. State environmental regulations govern the soil evaluation and percolation testing process.
How much does a perc test cost in California?
A perc test typically costs $500 to $1,500, including soil profile evaluation. Municipal fees for health officer oversight add $100-$400. Total costs vary based on regional regulatory requirements and professional standards.
What happens if my property fails the perc test in California?
If conventional perc test results do not meet state standards, you may be able to install an alternative system (mound system, drip irrigation, FAST unit) if site conditions allow. In densely developed areas, failing lots may have no viable septic option, requiring connection to public sewer if available.
Who can perform a perc test in California?
Soil evaluations and perc tests must be conducted by a **California-licensed Professional Geologist (PG)**, **Professional Engineer (PE)**, or other qualified professional approved by your **county Environmental Health** department. The evaluation must be witnessed or accepted per your county's procedures.
