Wasatch County Health Department requires a percolation test for every new septic system and subdivision development that will not be serviced by a sanitary sewer system. The percoaltion test helps evaluate the soils ability to absorb the effluent and transport it away from the absorption system. However, it is important that the soil be able to retain the effluent long enough to allow treatment to occur. Therefore, an ancceptable, peroclaction test will be within the range of 4 to 60 minutes per inch for a conventional septic system and 1 to 120 minutes per inch for some alternative septic systems.
Percoalation test cannot be done if:
- There is more than a foot of snow
- The ground is frozen
All perc tests must be coordinated with the Health Department and a $75 fee paid. The per test is not valid until all paperwork is filed with the Health Department.
Percolation test need to be done by State Certified Perc Testers.
