Summary
Johnson in 1990. This public utility facility plays a crucial role in treating wastewater from the city and surrounding areas, ensuring the protection of water resources and the environment. The facility is state-regulated and permitted, with a low hazard potential and fair condition assessment.
Situated near the Bitter Creek, a tributary of the Green River, Intercity Wastewater Treatment (Cell 1) serves as a key component in maintaining water quality and ecological balance in the region. With a storage capacity of 219 acre-feet and a surface area of 39 acres, this earth dam structure stands at a height of 10 feet and has a hydraulic height of 7 feet. Despite its high risk assessment, the facility is equipped with emergency measures and regularly inspected to ensure its proper functioning.
Managed by the SEO and under the jurisdiction of the state of Wyoming, Intercity Wastewater Treatment (Cell 1) remains a critical asset in safeguarding water resources and mitigating climate impacts in the area. With its strategic location and efficient operations, this facility exemplifies the importance of sustainable water management practices for the community and the environment.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
