Septic System Programs

The Environmental Services Division of Lewis and Clark Public Health manages a handful of programs aimed at ensuring that septic systems in the county work properly and do not pose a health threat to residents.
There are about 10,000 septic systems in Lewis and Clark County, and they discharge about 2 million gallons of wastewater (from toilets, showers, dishwashers, etc.) into our groundwater each day. A poorly maintained septic system has the potential to contaminate groundwater, creating a serious health hazard for those who rely on groundwater from wells for drinking, irrigating, washing and other purposes.
Onsite Wastewater Program
Works with property owners to properly site, or locate, a new septic system on a piece of property. A permit is required when siting a septic system to ensure that sewage is properly disposed of to protect the public's health, as well as the cleanliness of surface water and groundwater.
Septic Maintenance Program
Helps to ensure that owners of septic systems periodically inspect and pump the tank so that disease-causing germs are filtered out of the wastewater. An assessment form is available to help you determine how often you should have your septic tank pumped.
Septic System Loan Program
Provides low-interest loans to property owners who meet certain income requirements and have a septic system that needs to be repaired or replaced.
