The septic percolation test is completed to determine the suitability of a site for a subsurface private sewage disposal system (i.e. septic system). More specifically, a percolation test measures the ability of the soil to absorb liquid. Septic system designers or civil engineers use the results of percolation tests to properly construct septic systems.
The methods and requirements for septic percolation tests can vary by the governing agency. We are familiar with the methods and requirements for all of the local agencies including: the Arizona Department of Environmental Quality, Cochise County, Maricopa County, Mohave County, Navajo County, Pima County, Pinal County, Yavapai County and Yuma County. A compilation of the aforementioned agencies and their requirements for septic percolation tests are located here – Wastewater Treatment Facility Requirements.
