3 1500 miles of rivers and streams 20,000 acres of lakes and ponds Location, Location, Location Water supply issues vary with location in Rhode Island

4 Areas Currently Served by Major Water Suppliers In RI Green – grd water Red – surface water Yellow – mixed Other areas rely on individual wells

5 Wells and direct withdrawals effect stream flow

6 Water use affects surface water flows

7 Maintaining River Ecology A critical component of water supply management Ipswich River dewatered by water withdrawals in the watershed

16 The Hunt is not the only river stressed by current withdrawals

17 Watersheds of Concern Preliminary data indicates that the following watersheds may not be supporting the goals Preliminary data indicates that the following watersheds may not be supporting the goals We need to address the areas in Red through conservation and reduced demand. We need to address the areas in Red through conservation and reduced demand. –Hunt River –Chipuxet River –Westerly –Jamestown –Cumberland and Woonsocket We may be able to look for more water to supplement from the green areas. We may be able to look for more water to supplement from the green areas. Current demand < withdrawal standard Current demand may exceed Withdrawal standard Current demand exceeds Withdrawal standard Undetermined

18 Part II --- Curb Appeal Landscaping and water use on residential properties

19 Reducing residential demand: What works? Watering restrictions Once a week: reduced use 57% Twice a week: reduced use by 33% Price signals Fla. study: 50-80% price increase, 55% use decrease Irvine, CA: increasing block rates, 50% decrease in outdoor watering

20 Reducing residential demand: What doesn’t work? Automatic sprinkling systems Alternate day watering rules Voluntary programs

21 Save Water, Save Money Water Use and Efficiency Act 2009 Enforceable demand management programs (WRB) will encourage – –Reduction in summer peak – –Per capita water use goals Conservation pricing PUC rules Revenue stabilization funds

22 Water Use in the Home

23 Low Flow Toilets Toilets account for nearly 30 percent of an average home's indoor water consumption. Switching over to water-efficient plumbing fixtures could save the average household as much as $50 to $100 a year on water and wastewater bills. Older toilets typically used up to 7 gallons per flush, and then they 'evolved' to a more efficient 3.5 gallons per flush, and then to 1.6 gallons per flush. The new 'Low Flow' or 'High-Efficiency' toilets only use about 1.3 gallons per flush, and save your family between 8,000 and 20,000 gallons of water per year, per toilet over the 7 gallon models and save about 3,200 gallons relative to the 3.5 gallon models.

24 Dual Flush Toilets Older toilets use about 3.5 to 7 gallons per flush. Low flow toilets use only 1.6 gallons per flush and save between 8,000 and 20,000 gallons of water per year, per toilet. Dual-flush toilets take savings to the next level, because they have two buttons - one for a light flush at 0.9 Gallons and the other for a heavy flush at 1.6 gallons.

26 Shower Heads

27 Shower water use, national avg.* National Average Shower volume17.2 gallons Shower duration8.2 minutes Shower flow rate2.2 gallons per min. Daily per capita use11.6 gallons Showers per capita per day 0.67 showers per day * Mayer, et. Al, 1999 from www.h2ouse.orgwww.h2ouse.org

28 High performance showerheads Pressure regulated high-efficiency or high- performance shower heads save about 40% of the water required by conventional showers -- reducing the water flow from 2.5 Gallons Per Minute (GPM) to about 1.6 GPM. They also save energy when you use less fuel to heat the water for each shower. Each shower head now only costs between $40 and $60. New models provide ample pressure, and for a family of four, the savings can add up to hundreds of dollars per year and thousands of gallons of water.

30 Dishwashers

31 Saving water washing dishes A typical dishwasher uses between 8 and 15 gallons per load of dishes with an average of about 9.3 gallons per load (Mayer, et. al. 1999). Some manufacturers do offer high-efficiency dishwasher models. These dishwashers use less water and more significantly, less energy than the standard models. A high-efficiency dishwasher can wash a load of dishes using 5 to 7 gallons of water. A family that replaces a 12-gallon per load machine with a 6-gallon per load machine, and runs their dishwasher 4 times per week will save about 1,250 gallons of water per year.

32 Faucets

33 Faucet Water Use National Average* Daily per capita use10.9 gallons Avg. Faucet flow rate1.3 gallons per minute Daily per capita faucet use duration 8.1 minutes * Mayer, et. Al. 1999 from www.h2ouse.org

34 Water saving with faucet aerators

35 Washing Machines

36 Clothes washer water use rates National Average* Clothes washer load volume 40.9 gallons Daily per capita use15.0 gallons Frequency of use0.37 loads per capita per day * Mayer, et. al. 1999 from www.h2ouse.org

37 High-efficiency clothes washers Reduced the average volume per load by 40% overall. Hot water use was reduced by 63% and per capita use was reduced by 38%.

38 Water use varies by: Type of property. Single family vs. multi family Location. Urban vs. suburban Lot size (lawn size) Whether the property has in ground irrigation Residential vs. commercial

39 Water Used to be so easy!
