The Rawlins Wastewater Treatment Plant (St1) in Wyoming plays a crucial role in managing the local water resources and environmental sustainability. Designed by Mickey M. Yamashiro in 1978, this Earth dam structure on Sugar Creek, a tributary of the North Platte River, stands at a height of 17 feet and has a storage capacity of 152 acre-feet. The dam serves as a vital component in the treatment and disposal of wastewater, ensuring the protection of public health and the preservation of water quality in the region.

The Rawlins Wastewater Treatment Plant is state-regulated by the Wyoming State Engineer's Office, with regular inspections and enforcement measures in place to maintain its fair condition and significant hazard potential. The plant's location in Carbon County, Wyoming, highlights its importance in managing the drainage area and surface water resources effectively. Despite being a local government-owned facility, its impact extends beyond city limits, contributing to the overall water management efforts in the region.

With its high risk assessment and significant hazard potential, the Rawlins Wastewater Treatment Plant underscores the importance of efficient and sustainable water resource management practices. As climate change continues to impact water availability and quality, this facility stands as a critical infrastructure for safeguarding the environment and public health. The ongoing monitoring and maintenance of this Earth dam structure play a vital role in ensuring its resilience and effectiveness in the face of evolving environmental challenges.
