Located in Worland, Wyoming, the Worland Wastewater Treatment (Cell 4) facility stands as a crucial component in the state's water resource management infrastructure. Designed by JOHN W. DONNELL and completed in 1992, this Earth-type dam plays a vital role in regulating the Big Horn River's water flow. With a structural height of 15 feet and a capacity of 62 acre-feet, the facility serves as a key point of water storage and treatment for the region.

Operated by the local government, the Worland Wastewater Treatment facility has been deemed to have a low hazard potential and fair condition assessment. While it is state-regulated and undergoing regular inspections, the facility's risk assessment identifies a high level of risk, emphasizing the importance of effective risk management measures. With its uncontrolled outlet gates and proximity to the river, the facility plays a crucial role in ensuring water quality and environmental protection in Washakie County.

Despite its low hazard potential, the facility's high risk rating underscores the need for continued vigilance in maintaining its structural integrity and operational efficiency. As a critical piece of infrastructure in the region, the Worland Wastewater Treatment (Cell 4) facility stands as a testament to the importance of water resource management and climate resilience in the face of evolving environmental challenges.
