Common Programs and PracticesWhat Has Worked?
Mary Ann DickinsonExecutive DirectorAlliance for Water Efficiency
Conservation Benefits
• Drought Tool: Short-term relief
• Planning Tool: Lessen gap between demand and available supply
• Economic Tool: Defer capital facilities for drinking water and wastewater capacity and treatmento The US will spend a quarter trillion dollars by the
year 2020
Federal Incentives
• 1992 Energy Policy Act plumbing efficiency standards
Fixture U.S. Standard Metric EquivalentWater Closets (Toilets) 1.6 gallons per flush 6 liters per
flush
Showerheads 2.5 gallons per min 9.5 liters per min
Faucets 2.2 gallons per min 8.3 liters per min
Urinals 1 gallon per flush 3.8 liters per flush
• Drinking Water and Wastewater State Revolving Loan Funds
National Activity
• Over 15 State Conservation ProgramsoPlanning Requirements and Permit Hookso Implementation of specific programs
• Arizona; California; Colorado; Connecticut; Florida; Kansas; New Jersey, New Mexico; Oregon; Texas; and Washington State
• Seattle, Boston, Tampa, Austin, New York City, Los Angeles, San Diego and Las Vegas
How Much Can Be Saved?
• 1998 AWWARF Study of residential end uses in 1300 homes in twelve cities using data-loggers
• Without conservation, the household used on average 64.6 gallons per capita per day
• With conservation, the per capita per day figure is reduced to 44.7 gallons, or 30% savings

First Steps Are Easy and Free
Designate A Conservation CoordinatorDesignate responsibility within agency to an
individual identifiable to the public
Prohibit Obvious Water Wastage with Simple OrdinancesEnact and enforce local ordinances prohibiting
gutter flooding, single-pass cooling, non-recirculating systems in car washes and commercial laundries, non-recycling decorative fountains
Educate the Public
Public Information ProgramsProvide speakers, advertising, and other
information to promote water conservation
School Education ProgramsWork with school districts by providing
materials for water conservation instruction
Next Steps
Audit Your Water System and Repair LeaksConduct system audit with the new methodology Monitor water delivery system for leaks and make
cost-effective repairs
Meter With Commodity RateMeter all new connections and bill by volumeRetrofit unmetered connectionsConsider installing dedicated landscape meters
Next Steps
Explore Conservation Rate Pricing
Adopt water rates that provide an incentive to
customers to reduce average or peak use
If utility provides both water and sewer service, apply
conservation pricing to both
Typical Residential Programs
Conduct Residential AuditsOffer residential customers water-use surveys
which include checking for leak, flow rates, irrigation systems and schedules. Try contacting 20% of your customers each year to offer surveys. Offer incentives and devices.
Retrofit Residential Plumbing Best when tied to the audit program.Provide 2.5 gallon-per-minute or less
showerheads and aerators and toilet displacement devices.
More Residential Programs
Replace Old Toilets with ULFTsImplement a program to replace high-water using toilets with
1.6 gallon per flush models or new higher efficiency toilets
Retrofit High-Efficiency WashersProvide rebate to encourage purchase of high-efficiency
clothes washing machinesNew national standard taking effect in 2007
Large User Programs
Examine the Commercial, Industrial, Institutional AccountsIdentify and rank customers in each customer
classRetrofit high-water using toilets and clothes
washersLook at high water using processes for
possible efficiency improvements (cooling towers, one-through cooling, etc.)
More Commercial &Industrial
Examine Large Landscape AccountsEncourage dedicated landscape meters:
assign a yearly or adjusted monthly water budget of <100% ETo
Tie water budgets into rates for penaltiesExplore new irrigation technologiesOffer incentives to minimize irrigation needsFor mixed-use meters: offer surveys to 20%
of customers
Effects of Growth
Water Resources and Population Growth, 2000-2020Source: DOE/NETL (M. Chan, July 2002)
The Facts
• ½ of homes that will exist in 2030 have not yet been built
• Studies are showing that new homes are using 12-60% 12-60% more water than their existing counterparts
• High water use not just a function of high-end homesoShower “systems”oAutomatic and excessive irrigationoHot Water Wastage
Incorporating Water
• Water efficiency a new partner in green building programs oUSGBC LEEDoNAHBoASHRAE
• 30%30% or more savings are possible
• With high efficient technology, over 1 billion1 billion gallons per day could be saved by 2015
The Facts
• Higher efficiencies being developed in products and appliances
• “Hardwiring” savings the best option
• More savings than voluntary programs
• State legislation, regulations, and ordinances
• Code and Standards changes
• Water Labeling Program similar to Energy Star
• Program announced by EPA Administrator in June, 2006
• High Efficiency Toilets already labeled – nearly 100 models
• Other products now under review
• Labeling candidates under review:o Bathroom faucets o Weather-based irrigation controllers o Soil moisture sensorso Drip irrigation systemso Commercial toilets, urinals, faucets, laundries, etc. o Autoclave water valveso Food Steamerso Pre-Rinse Spray Valveso Clothes Washers
Updates on EPA’s websitehttp://www.epa.gov/watersense
And the Consumer?
• Average US Consumer not aware of shortage issues, supply problems, or even economical efficiency opportunities
• Ethic slow in developing
• No effective national campaign exists similar to those in energy
Water vs. Cable
• Subsidies mask true costs of supply and distribution
• Utilities not valuing water efficiency programs at avoided costs of supply
• Environmental benefits not adequately valued in cost-benefit analyses
• Water Pricing still difficult: a fraction of a cable bill for a truly needed commodity
