Water Wise 2011— Tell Your Water Tale
Purpose of the Water Efficiency Program
Comply with 2000 GUP requirements
Stay within SFPUC allocation of 3.03mgd
Provide high quality water for research, academic, & new facility uses
Use water efficiently to stretchStanford’s supply
Key Program Elements at Stanford
Integrate water use data with water management practices
Understand water use patterns and trends Create a customer communication network to
gather and disperse information Establish a network with equipment suppliers
and experts Test new products, with lots of pilots starting on
a very small scale
A History of Conservation—Stanford’s Potable Water Consumption
Despite adding more than 1 million GSF to the building portfolio, Stanford’s potable water use is about 20% lower now than in FY2000.

Stanford’s Water Efficiency Goals
The water efficiency program aims to reduce water consumption of fixtures systematically throughout the Stanford campus, targeting both retrofits and new construction.
A Path to Sustainable Water Use
Analyze existing water use & identify opportunities for improving efficiency
Explore and test new technologies
Manage wisely and preserve resources for the long term
Capture and reuse water where practicable and develop a variety of local alternate sources
Reduce Demand Enhance Supply
Not Successful on Campus Successful Pilots on Campus
Water Mizer Low-flow Faucets
High-efficiency urinals and toilets (0.125 and 1.28 gals/flush)Currently in Pilot Phase
Low-flow Showerhead
Low-flow Pre-rinse Nozzle
Real-time metering device
Stanford’s Demonstration Programs
A Success Story: Beckman CenterFY 2002 – FY 2011 YTD Water Use
13 water mizersinstalled June 15, 2004
35 HETs, 32 HEUs, and 10 Faucets installed MAR-05 Bill Period
Decreased consumption by 50% since 2003.

Irrigation Lake Water—An Opportunity for Further Conservation on Campus
Lake water is the primary source of landscape irrigation water. Efficient use of lake water for this purpose reduces the potable water required to meet demand.

Tell Your Water Tale—Your Participation
Individual Action Steps:
Keep an eye out for leaking water, broken sprinklers, or irrigation water running down pavement into gutters.
Note the time, date, and approximate location of your observation.
If possible, take a photograph to assist repair crews with location and problem identification/classification.
Complete the online water action report. Go to http://sustainablestanford.stanford.edu/be_cardinal_green_waterwise
The online water action report is the key for all Stanford community members to participate in the Water Wise 2011 campaign. Information collected will be forwarded to the appropriate parties for timely action. All participants will be entered into a weekly raffle, and a final summary report will be sent to all participants at the end of the campaign.
