2 Outline Introduction Benchmarking What is a water audit? Advantages of benchmarks & audits Case Studies Further resources Benchmarking What is it? A tool to help improve your business or building s performance A way to track and measure progress toward goals Standard of excellence within an industry Helps identify cost savings opportunities Part of a 4 step process: Benchmark, Audit, Implement, and Repeat

3 Water Use Benchmarks What is water use benchmarking? Benchmarking is a tool which can help you to improve your processes, products and services by comparing your business' performance with that of similar organizations. It can help you to identify processes that you can adopt to reduce your business' use of water and cut costs. Water Use Benchmarks How does this apply to water use? How will it affect me?

4 Water Use Benchmarks California s Hydrologic Regions

5 Water Use Benchmarks How Does this Affect You? CII (Commercial, Industrial, Institutional) Taskforce being created (DWR/CUWCC) Stakeholders will be invited BMPs to be developed Water use reduction targets to be set

6 Water Audits Water audits are a key part of water management. They are essential to gathering the facts and analyzing them so as to provide management with options, costs, savings and financial returns. Audits form the basis for the sound decision making in the allocation of always scarce capital. Water Audits AKA Water Use Survey Available Free from Many Water Agencies Measures baseline water use Provides recommendations for increased efficiency Estimates costs, savings & payback time for recommended changes May include free replacement of faucet aerators, shower heads and other items

7 Water Audits Examples of commercial water audit programs include: Santa Clara Valley Water District usiness/indoor%20water%20use%20survey_10_08.pdf?n=4085 City of Austin, Texas City of Portland City of Albuquerque Tampa Santa Rosa, California rosa.ca.us/default.aspx?pageid=2265 Cochise County, Arizona Value of Benchmarks & Audits Risk Management $$$$ PR Green/Sustainable Impact of recent legislation New codes and standards

8 Value of Benchmarks & Audits Risk Management: Preparing for Water Supply Variability & Vulnerability Periodic droughts are part of natural cycle, but climate shift is making things worse. Less runoff = less storage = vulnerability in times of shortage. Environmental water needs driving pumping cuts in the Delta. Population growth continues to drive need for more water supply, even as per capita needs goes down. Efficient water use now prepares your facility for future supply shortages or limits. Value of Benchmarks & Audits $$$$! Water efficiency improvements made based on benchmark goals and water use audits will likely produce significant savings on: water energy waste water chemical & other costs

9 Value of Benchmarks & Audits P.R. Public Relations or Public Recognition? Both!

10 Value of Benchmarks & Audits Green/Sustainable Growing trend toward sustainability Water conservation /efficiency is Green & Sustainable Extra savings: lower energy & waste water costs Water efficiency linked to lower energy use & GHGs Saving water saves more water Value of Benchmarks & Audits More Reasons to Measure: Impact of recent legislation Impact of new codes and standards

11 More Reasons to Measure Legislation: SBx7 AB 811 SB 790 AB 1881 President Obama s Executive Order #13123 More Reasons to Measure Codes and Standards SF Green Building Code New LEED standards re: water use New IAPMO Green Supplement WaterSense

15 Case Studies The Campbell Union School District: Savings on irrigation water use as result of a water audit Cisco Systems: Variety of savings at San Jose Campus SAB Miller Brewing: More Beer, Less Water Wal Mart: Sustainability Index Local Award Winners

16 Case Study: Campbell School District Greenscape Management The Campbell Union School District participated in a water use audit (courtesy of Santa Clara Valley Water District) Replaced ordinary manual irrigation timers with 45 smart controllers at 12 sites/schools The District reduced annual landscape water use by 39% Saved more than 35 million gallons of water Realized $108,000 in savings last year. Case Study: Cisco Systems By retro commissioning variable frequency drive and HVAC systems, the Cisco Systems campus in San Jose now saves 22 million gallons of water per year. Water efficiency programs for: cafeteria kitchens locker room showers bathrooms landscaping cooling towers.saves another 20 million gallons per year.

17 Case Study: Cisco Systems Cisco recently installed 99 evapo transpiration irrigation controllers with rain sensors, resulting in a 21% reduction in landscape water use. Converted 12 large display fountains into planter beds; utilize drought tolerant plants, drip irrigation and mulch to reduce water use throughout the campus. Recycled water for landscape irrigation and display fountains represents 30% of water consumption. Case Study: MillerCoors To make more beer with less water, MillerCoors has developed a water management strategy that focuses on four key areas: 1) Water usage and Efficiency 2) Wastewater quality and management 3) Supplier relationships 4) Community relationships
