(The better all the elements are managed, the better the impact on safety, reliability and cost.) 16
Water Reuse in the U.S. Solaire, Battery Park Wrentham Mall Water reuse in the U.S. is a large and growing practice An estimated 1.7 billion gallons per day is reused Reclaimed water use on a volume basis is growing an estimated 15% per year In 2002, Florida reclaimed 584 mgd; California ranked a close second with 525 mgd used everyday New Jersey Antham Florida has an official goal of reclaiming 1 billion gallons per day by the year 2010 Foxboro 17

Water Resource Solution Cycle Water Resource Challenges Technology Solutions Innovative Solutions are needed to break this cycle! Drought, Saltwater Intrusion, Unpredictable Weather Patterns Increased Energy Consumption Climate Change 23
How Much Electricity Does the Water Industry Use? Drinking water and wastewater consume: 3% of domestic electricity1 7% of worldwide electricity 19% of California electricity2 1. 2. 3. Water utility energy use varies widely from 0.25 to 3.5 kwh per 1,000 gallons of drinking water produced and delivered3 The median 50% of water utilities serving populations >10,000 had electricity use between 1.0 and 2.5 kwh/1,000 gallons3 Electric Power Research Institute (Burton 1996) Energy Down the Drain: The Hidden Costs of California s Water Supply AwwaRF 91201.Energy Index Development for Benchmarking Water and Wastewater Utilities 24

Conclusions Addressing climate change makes good business sense Water utilities are not just the recipients of the effects of climate change, they are also part of the problem! Multiple mechanisms exist for water systems to control impact climate change Reduce electrical use Remember: 80-90% of water treatment plant electric consumption goes to pumping Look beyond just reducing electrical use be creative! 26
