Energy Workshops for Water and Wastewater Agencies - The Bottom Line

1. Energy Workshops for Water and Wastewater Agencies - The Bottom Line • The potential exists for regional energy shortfalls this Summer • In the future, the gap between power generation and peak demand will increase • Energy intensity of water is high, but opportunities for reductions exist

2. Energy Workshops for Water and Wastewater Agencies - The Bottom Line • It takes energy to lift weight – each day during the summer the State Water Project lifts approximately6 million tons of water at Edmonston. • Approximately 60% of the water is pumped during 8 off-peak hours when the system is fully ramped up.

6. Energy Workshops for Water and Wastewater Agencies - The Bottom Line Energy companies, water and wastewater agencies have much more they could do: • Work together to improve overall efficiency of operation and meet future water and wastewater quality requirements • Find areas of mutual interest : • saving electricity by saving water • save electricity and gas by saving hot water • Improve cooling tower efficiency both for time of use and shift off peak • Develop a message in common with Flex Your Power

7. Energy Workshops for Water and Wastewater Agencies - The Bottom Line For customers, the basic message is: • conservation and shifting the peak • Especially discretionary water use, such as landscape watering, • saving water saves energy • indoor water efficiency saves more energy indoor hot water efficiency save the most energy inside the house • water conservation measures can reduce the size of the peak

8. Energy Workshops for Water and Wastewater Agencies - The Bottom Line • It is possible to achieve a triple bottom line of financial, social and environmental savings through conservation and shifting water use off the peak demand period.
