The Natrona County Wastewater Program at the Casper-Natrona County Health Department is meant to provide a sanitary and environmentally responsible way of disposing of domestic wastewater that will minimize the impact on ground and surface water as well as reduce exposure to potential disease-causing organisms. Program oversight is limited to less than 2000 gallons/ day of domestic sewage for each household or business.

Our department licenses septic installers as well as permits the wastewater system itself.
