Small Wastewater Systems
Permit Jurisdiction
DEQ authorizes permits to construct for small wastewater facilities, defined by Wyoming Statutes 35-11-103(c)(ix), that are located in Campbell (commercial systems only), Carbon, Niobrara, Platte, and Weston Counties where DEQ is the permitting authority. The permitting authority for other jurisdictions may require different forms or additional information. See the Small Wastewater Permitting Authority document in the Permitting Forms and Information tab.
Small Wastewater System Permitting Instructions:
Step 1: Review the Small Wastewater Facility General Permit, which covers the installation, repair or replacement of individual or commercial sewage disposal systems that treat less than 2,000 gallons of domestic sewage per day. See “Permitting Forms and Information” tab.
Step 2: Complete the Conventional-Septic-System-Application-Package. A List-of-approved-septic-tank-models and providers is available to help you select your tank. See “Permitting Forms and Information” tab.
Step 3: For applications within DEQ jurisdiction, submit 1 hard copy of the application package and leachfield design sheets to the District Engineer for the county (see District Map) in which construction will take place, and one electronic copy to the WDEQ Water Quality Division Document Uploads link above.
Step 4: The permitting authority will review the submitted application package. Once approved, the permitting authority will transmit a permit to construct or a notice of coverage that authorizes construction activities. Construction may not commence until the permitting authority issues authorization.
Step 5: Submit a Certificate of Completion to DEQ when installation is complete. See “Permitting Forms and Information” tab.
Submit a Transfer of Ownership form if the ownership of a permitted facility is transferred to another party. See “Permitting Forms and Information” tab.
Submit a Certificate-of-Completion to DEQ when installation is complete. See “Permitting Forms and Information” tab.
