Small Wastewater Systems

Septic system permits are required for the installation, repair or replacement of individual or commercial sewage disposal systems that treat less than 2,000 gallons of domestic sewage per day.  If your facility treats more than 2,000 gallons of sewage per day, contact the Underground Injection Control (UIC) Program.

This permit is to be used only for the construction of small wastewater facilities located in Campbell (commercial systems only), Carbon, Crook, Niobrara, Platte, and Weston Counties where DEQ is the permitting authority. If your septic system will be located in any other county, the permitting authority for that county may require different forms or additional information.
