We regulate the installation, repair, and maintenance of septic systems for homes and businesses not served by community sewer systems.
Starting Oct. 4, Septic will be online on Development Direct.
To prepare for the move to online, we will not be able to accept any septic permits Sept. 29 – Oct. 3. We apologize for any inconvenience.
Septic and onsite wastewater treatment systems must be designed, installed, and maintained to protect:
- public health by properly treating and disposing of disease-causing human waste
- the groundwater aquifer and surface waters from pathogen and nitrogen contamination
