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:

1. There is more than a foot of snow
2. 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.

To better protect groundwater, a minimum of 48 inches is the required separation between the bottom of the absorption system and highest groundwater table. If your lot is suspected of, or has been identified as having a high groundwater table, then it is the owner's responsibility to contact Wasatch County Health Department and fill out the application for groundwater monitoring. Groundwater monitoring shall be conducted by the owner for a period of one year, with more frequent readings from early spring through late summer. A second year of monitoring may be required during dry years where water precipitation is less than 85 percent of the norm. All water monitoring data must be submitted to the Environmental Health office prior to the issuance of the septic permit.
