What is a perc test and why is it required?
A perc test (percolation test) measures how quickly soil absorbs water. It is required in most Central Valley counties to determine if a property can support a septic system. Results help establish system design feasibility and permitting approval.
How long does a perc test take in the Central Valley?
Most perc tests take a few hours to complete in the field. Some sites may require a second day for a presoak and follow-up testing depending on soil type and county requirements. Reporting time varies based on site complexity.
Can you help with county permitting and submittals?
Yes. Support is provided for required documentation, reports, and coordination with county environmental health departments to help move projects through the approval process.
What happens if my soil fails a perc test?
A failed perc test does not always mean a property is unbuildable. Alternative septic system designs may still be possible depending on soil conditions, lot size, groundwater depth, and county regulations.
Do I need a perc test before building a home?
Yes, in most unsewered rural areas of the Central Valley. Counties typically require a passing perc test before issuing permits for homes that rely on onsite septic systems.
How long does septic system design take after testing?
Design timelines depend on soil results, property layout, and county review requirements. Straightforward sites may move quickly, while complex systems require additional engineering and revisions for approval.
What counties do you service?
Services are available across the Central Valley, including Tulare County, Kings County, Madera County, Kern County, and Merced County areas. Additional regions may be considered depending on project scope.
What determines if a property is suitable for a septic system?
Suitability depends on soil percolation rate, groundwater depth, usable land area, slope, setbacks, and county environmental health requirements. These factors are evaluated during testing and design.
Do you provide both perc testing and septic system design?
Yes. Perc testing and septic design can be completed separately or as part of a full site evaluation. This creates a streamlined process from field testing through permitting.
