Energy Efficiency Philosophy Provide a high quality, sustainable water supply that is safe, reliable, and delivered at a cost-effective price Transitioning the Production System Operation Strategy: Demand Based to Efficiency Based Leverage utility programs, grants and incentives to achieve innovative and verified energy savings while boosting performance of their system in ways that may be replicated by other agencies. Leveraging nearly $333,000 (grant/incentive) funding with anticipated annual savings of $449,000

Working Toward This Goal CVWD Production and Controls Staff Third Party Consulting Honeywell Southern California Regional Energy Network (SoCalREN) Authorized by the California Public Utilities Commission - 2012 to harness the collective power of residents, businesses, and the public sector to achieve an unprecedented level of energy savings across Southern California. Identify energy saving measures and work side-by-side from design through construction All services provided by SoCalREN are provided at no cost Arrange financing and handle the utility rebate incentive process on your behalf. Provide access to on-call, high-quality energy retrofit construction professionals through the National Joint Powers Alliance (NJPA).

Pump Efficiency Improvements Goal Evaluate existing equipment for reasons of inefficiency and restoration of OEM specifications, or implement a design change to meet current system conditions Project Description CVWD worked together with The Energy Network using an SCE customized incentive of $0.08/kWh and $150/kW capped at 50% of project cost Thirteen vertical turbine pumps (4 wells/9 boosters) identified as operating outside of the acceptable plant efficiency (Boosters < 72%, Wells < 71%) Pull and repair the identified pumps Three requests for proposals/three separate contractors to pull and repair the pumps

Pump Efficiency Improvements Results Each contract was completed on time, within budget, and efficiencies were brought up to acceptable levels Installed Measure Cost $720,986 Verified Incentives: $184,556 Verified Savings: 2,191,098 KWh/Year

Optimize Booster Pump Sequencing 3 and 3a Goals The seven (7) booster pumps located at Stations 3 and 3A were identified as potentially benefiting from optimization of the booster pump sequencing with a goal of operating the optimum amount of vertical turbine pumps in the most efficient sequence Project Description The two pump stations boost well water from Reservoir 3 and 3A to Zone 4 Pump Station 3A Boosters 1 - 539.9 kWh/AF 2 - 543.7 kWh/AF 3 - 593.0 kWh/AF Pump Station 3 Boosters 1 - 377.2 kWh/AF 2 - 392.4 kWh/AF 3 - 402.0 kWh/AF 4 - 364.0 kWh/AF Design of subzone 4 in zone 5

Optimize Booster Pump Sequencing 3 and 3a Results Installation of 3 pressure regulating valves and booster sequencing programming This project was recognized as an area in need of stabilization and a capital improvement project was designated to address the pressure stabilization Installed Measure Cost $249,650 Verified Incentives: $56,543 Verified Savings: 2,191,098 KWh/Year

Optimize Well Pump Sequencing – In Progress Goals 24 well pumps identified as potentially benefiting from sequencing Provide more frequent data to re-evaluate the pump sequencing Project Description Operational Efficiency determined by kWh/Acre Foot Installation/Integration of individual electrical sub-meters Energy data, system demand and water quality data to provide an operations strategy which incorporates an energy efficiency control strategy

Optimize Well Pump Sequencing – In Progress Results Installed Measure Cost $94,800.00 Estimated Incentives: $36,974.16 Estimated Savings: 462,177 KWh/Year

Optimize Booster Pump Sequencing – In Progress Goals 47 booster pumps and 9 well identified as potentially benefiting from sequencing Project Description Re-evaluate the pump sequencing in order to more efficiently meet system demand Booster pumps with lower energy intensities used to meet a greater portion of the system demand Installation/integration of electrical sub meters for each of the identified pumps This metered data was incorporated into the control scheme and is being used to give another metrics variable in system operation Results Installed Measure Cost $128,000 Estimated Incentives: $54,925 Estimated Savings: $74,600/Year

Energy Efficiency Progress With the completion of energy efficiency measures 1 and 2 the District has realized a decrease in ground water pumping costs from $245/Acre Foot (FY2015) to $190/Acre Foot (FY2017)

Innovation CVWD identifies areas capable of optimization and searches for methods to leverage resources to achieve a maximum benefit CVWD/SoCalREN partnership provided a method to leverage technology in a way which increased both efficiency and reliability CVWD provided resources contributing in the areas of design, installation, and integration of the controls.

Mission/Vision Provide high quality water while practicing good stewardship As good stewards CVWD is constantly looking for the highest value in projects. Value is rated with metrics including project cost, return on investment, and long term gains Through innovative processes, we were able to bring two groups of people together and develop projects which increased employee knowledge in the area of operations. This increased knowledge not only resulted in a successful high value project, but also increased the reliability of service.
