Onsite Wastewater Systems


A residence or other building must have a way to address wastewater generated on the premises. In most cases the building is connected to the municipal sewer. If the municipal sewer is too far away, the property owner may have the option of installing an individual onsite wastewater system (i.e. septic tank and drain field) for the treatment and dispersal of wastewater. Not all properties meet requirements of state law for the installation of onsite wastewater systems (OWS).

Onsite Wastewater Applications and Resources


Developing an Onsite Wastewater System

Statement of Feasibility

In order to develop a raw (undeveloped) property, a Statement of Feasibility is required. To initiate the process to obtain this document, the applicant will complete an Onsite Wastewater System Application. Our office will conduct a GIS assessment, a records search, a site assessment, and a soil evaluation. We will also oversee required percolation tests and ground water monitoring. Based on the feasibility studies, if the property meets the legal requirements, we will issue a Statement of Feasibility allowing development on the property. 

Inspection Requirements

The inspector must assess the construction to insure proper excavation and installation of a onsite wastewater system. It must meet the requirements of the approved plan and be in compliance with the Rule R317-4. Of primary concern is whether the septic tank and drain field/deep trench have been sized and located properly for health and safety. The excavation cannot be back-filled until the health inspector has given final approval.

Existing Onsite Wastewater Systems

Locating an Existing Septic System

If you need help locating an existing septic tank, please submit an Onsite Wastewater System Application. When we receive this application, we can search our records and provide any information that we have regarding the system on your property.

Connecting to the Sewer

Municipal and state laws require that if a property is within 300 feet of a public sewer, the city or county may require sewer connection of any occupied buildings on the property.

Abandoning an Existing Septic System

To properly abandon a septic system, you must notify the health department within 72 hours prior to any excavation or construction. Then the septic tank must be pumped and removed or crushed in place and void filled or completely filled with earth sand or gravel.

When connecting to the sanitary sewer the building sewer must bypass the septic tank and slope at  ΒΌ inch per foot to the municipal or district sewer main. A clean out within two feet of the foundation is generally required by the building code.

Northwestern Davis County Groundwater Study

in 2022, Davis County conducted a study of groundwater conditions in the northwestern, Hooper area of Davis County.  The purpose of the study was to determine the impact that septic systems have had on the groundwater in the area, and to get recommendations for septic system densities going forward.  The study found elevated levels of pollutants in the groundwater, indicating that it had been impacted by septic systems and other sources of contamination.  The study also concluded that a density of about 10 acres per septic system should be maintained in order to not further deteriorate the groundwater quality.

The study's objectives, activities, findings and recommendations can be viewed on the Davis County Septic Analysis Storyboard.
