Summary

This system, completed in 1995, consists of an earth dam with a hydraulic height of 15 feet, providing a storage capacity of 168 acre-feet. Situated near the Columbia River, this system covers a surface area of 6.3 acres and is regulated by the Washington Department of Ecology.

With a significant hazard potential and a satisfactory condition assessment as of August 2018, the Pasco Industrial Wastewater System is subject to regular inspections every five years to ensure its operational integrity. The system is designed to manage industrial wastewater effectively while also serving irrigation needs in the region. As climate change continues to impact water resources, the importance of sustainable management and regulation of wastewater systems like Pasco's becomes increasingly crucial to protect the environment and public health.

As enthusiasts for water resources and climate issues, it is important to acknowledge the role that infrastructure like the Pasco Industrial Wastewater System plays in managing water resources in a sustainable manner. By staying informed and engaged in the regulation and maintenance of such systems, we can contribute to the preservation of water quality and the overall health of our environment for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
