  • Onsite Wastewater Treatment (Septic) Systems


    Unlike the cesspools on grandpa's farm, the modern onsite wastewater treatment system, or OWTS, is an environmentally sound method of wastewater disposal in areas where public sewers are not available. These are also referred to as septic systems.

    Since many homeowners have little or no experience with an OWTS, these pages will provide information to help you understand how your OWTS functions and ways you can help improve its operation, such as:

    • Do not dispose of items that will destroy the natural digestion processes in your OWTS
    • Do not overload the system with excessive water
    • Have the tank regularly inspected and pumped.


    If you adhere to these few simple rules, your OWTS will prove to be a safe and economical onsite method for disposing of your rural wastewater. To learn more, see our other pages on OWTS systems.

    See our Environmental Health Services Forms and Applications page, Onsite Wastewater Treatment Systems section, for all of the associated documents on onsite wastewater treatment systems.
