Onsite Wastewater Systems

A residence or other building must have a way to remove wastewater from 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 wastewater system (i.e. septic tank and drain field) for the disposal of wastewater. Not all properties meet requirements of state law for the installation of onsite wastewater systems (OWS). 


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 a Feasibility Assessment 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.
More information regarding Feasibility Assessment criteria can be found here.

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

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.

Locating an Existing Septic System

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