CVWD upgraded its control system (Programmable Logic Controllers, communications, and Human Machine Interface) in an effort to provide a structure to incorporate an energy efficiency operations strategy

14. 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

15. 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

16. 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

17. 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

18. 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

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

21. 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

22. Water - Boosters

23. 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)

24. 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.

25. 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.
