General Information Title Wastewater Treatment Plant Improvement Total Budget $4,000,000 Funding Match 25% Local Match/Possible attainment of DAC status waiver Funding Request $4,000,000 Can a detailed cost Preliminary cost estimate available estimate be provided upon request? Location: City of Wheatland Latitude Longitude Could you provide a map of Yes the project location including boundaries upon request? Location City of Wheatland Malone Drive adjacent to Bear River Description: County Yuba Counties City/Community City of Wheatland Watershed/subwatershed Bear River Watershed Groundwater Basin Yuba Groundwater Basin, South Yuba Sub-basin Type Facility Construction Restoration Best Management Practices III. Description The Wastewater Treatment Plant Improvement will convert Wheatland s existing plant from a secondary to tertiary treatment plant, relocate the infiltration basins from the flood plain to the Page 1 of 5

2 protected side of the Bear River Levee and provide equipment to provide safeguards from potential sewer overflows. IV. Rationale/Issues Statement The City of Wheatland wastewater treatment plan currently has a lack of redundancy (that is found in modern plants), and the plant infiltration ponds are currently on the river side of the Bear River levee. In 2005, the river rose to a near flood stage level and washed the City's infiltration ponds away resulting in a direct discharge of secondary treatment effluent into the Bear River. The project addresses the need to improve wastewater management and reduce potential water quality impacts from unanticipated discharges. The project also gives the City of Wheatland the opportunity to convert some of the new infiltration ponds into storage for recycled water. This project specifically addresses the following regional issues: Wastewater Management Improve wastewater management and manage water quality impacts from spills and discharges while addressing the rising costs of operation and regulatory compliance Water Use Efficiency/Water Conservation Promote and implement policies and practices to increase water use efficiency and water conservation in municipal and agricultural sectors Regulatory Compliance Mitigate for the impacts of regulatory compliance on water management decision-making and processes, including increased costs and decreased opportunities for collaboration V. Goals/Objectives/Performance Metrics Goals Addressed by the Objectives Addressed by The Goal of the Wastewater Treatment Plant Improvement project is to protect, restore and enhance water quality for water users and in support of healthy watersheds (Goal 2). Additionally, the project would equip the wastewater treatment facility with the infrastructural capacity to store water for re-use as recycled water, therefore potentially ensuring adequate and reliable water supply that meets the diverse needs of the region (Goal 1). The objective addressed by the Wastewater Treatment Plant Improvement project is to minimize water quality impacts from effluent discharges and wastewater spills. The project specifically addresses the following Plan objectives: 2.2 Minimize water quality impacts from flood, effluent discharge and wastewater spills; 2.6 Support regulatory compliance with current and future state and Page 2 of 5

3 federal water quality standards; 1.1 Improve water supply system capacity, flexibility and efficiency, including, but not limited to, optimizing existing water storage; upgrading and retrofitting aging infrastructure; and, developing new infrastructure, where necessary; 1.2 Promote water conservation and water use efficiency by instituting various techniques including, but not limited to, groundwater recharge, conjunctive management, irrigation efficiencies, municipal water conservation, water recycling and reuse What performance metrics will be used to demonstrate that objectives are being met? Wherever possible, provide a quantitative measurement reflecting successful project outcomes. The project success will be measured by obtaining plant recertification with the Regional Water Quality Control Board. Attain tertiary level water quality. VI. Resource Management Strategies Reduce Water Demand Agricultural Water Use Efficiency Urban Water Use Efficiency Improve Water Quality Pollution Prevention Practice Natural Resources Stewardship Recharge Areas Protection Improve Flood Management Flood Risk Management Recycled water Recycled water The project incorporates improved water quality strategies by relocating the infiltration ponds to eliminate a direct discharge of secondary treatment effluent into the Bear River. Redundant equipment will reduce risk of sewer overflows. Through the use of rapid infiltration basins on the landward side of the levee Removes critical facility from the flood plain VII. Statewide Priorities Drought Preparedness Promote water conservation, conjunctive use, reuse and recycling Improve landscape and agricultural irrigation efficiencies Achieve long term reduction of water use Efficient groundwater basin management Use and Reuse Water More Efficiently Page 3 of 5

4 Increase urban and agricultural water use efficiency measures such as conservation and recycling Climate Change Response Actions Adaptation to Climate Change: Use and reuse water more efficiently Adaptation to Climate Change: Establish migration corridors, re-establish river-floodplain, hydrologic continuity, re-introduce anadromous fish populations to upper watersheds, enhance and protect upper watershed forests and meadow systems Reduce Energy Consumption: Water recycling Practice Integrated Flood Management Better emergency preparedness and response Protect Surface and Groundwater Quality Protecting and restoring surface water and groundwater quality to safeguard public and environmental health and secure water supplies for beneficial uses Ensure Equitable Distribution of Benefits Develop multi-benefit projects with consideration of affected disadvantaged communities and vulnerable populations Climate Change Adaptation The project will assist in adapting to regional effects of climate change by improving the wastewater treatment plant to use water more efficiently, by removing wastewater ponds from restricting river flow and by giving the City of Wheatland the ability to convert some of the infiltration ponds into storage for recycled water, allowing for reuse of water. GHG Emissions Reduction This project would reduce GHG emissions by increasing the energy efficiency of the wastewater treatment plan by upgrading pumps, reducing peak hour energy use, and by developing the capability for water reuse and recycling.

List technical reports and studies supporting the feasibility of this project. If you are an Urban Water Supplier: 1. Have you completed an Urban Water Management Plan and submitted to DWR? 2. Are you in compliance with AB1420? 3. Do you comply with the water meter requirements (CWC Section 525)? City of Wheatland General Plan Correspondence and meeting minutes from the Regional Water Quality Control Board. Wastewater Treatment Plant Reliability Study (April 2011) Not Required Wheatland s is not considered an Urban Water Supplier (UWS) since its current water use is below DWR threshold for UWS. If you are an Agricultural Water Supplier: 1. Have you completed and submitted an AWMP? If the project is related to groundwater: 1. Has GWMP been completed and submitted for the subject basin? Yes See Yuba County Water Agency Ground Water Management Plan. Page 5 of 5
