• It takes energy to lift weight – each day during the summer the State Water Project lifts approximately 6 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.

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
Energy Workshops for Water and Wastewater Agencies - The Bottom LineThe 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
Energy Workshops for Water and Wastewater Agencies - The Bottom LineThe 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.
