  • 2. key principles
    Protect Natural Systems
    Promoting and protecting natural waterways as ASSETS
    Integrate Storm Water Treatment into the Landscape
    Use storm water in the landscape
    Leverage its aesthetic qualities within parklands and walking paths, making use of natural topography
    Protect Water Quality
    Improve the quality of water draining from urban developments into receiving environment, use filtration and retention
    Reduce Runoff and Peak Flows
    Reduce peak flows from urban development by local detention measures
    Minimize impervious areas
    Add Value While Minimizing Development Costs
    Minimize the drainage infrastructure costs

  • 3. consumption stats

    Information provided by author, Peter Coombs
  • 4. local stats.
    Average household spends $500/yr on water and sewer
    If all U.S. households installed water-efficient appliances;
    3 trillion gallons of water saved
    $18 billion dollars per yearsaved
    YOU can save $170/year by making simple modifications to your existing home
    kingswood co., llc
  • 5. national stats
    Public supply and treatment facilities consume;
    56 billion kilowatt-hours (kWh) per year
    Enough to power more than 5 million homes for an entire year
    If one out of every 100 American homes retrofitted with water-efficient fixtures,
    save about 100 million kWh of electricity per year
    avoiding 80,000 tons of greenhouse gas emissions
    removing nearly 15,000 automobiles from the road for one year!
    If 1 percent of American homes replaced their older, inefficient toilets with Water Sense labeled models,
    save more than 38 million kWh of electricity
    enough to supply more than 43,000 household’s for one month

    Bathroom Sink Faucets
    save more than 60 billion gallons of water/year
    more than 1.2 trillion gallons of water/year
    save nearly 2 billion gallons per day
    80 percent of the urinals in use today (9.6 million fixtures) exceed the maximum allowable flush volume set by federal standards
    save between 1.0 and 4.5 gallons per flush
    kingswood co., llc
  • 8. epawatersense
    pre 1992: 3.5 g per flush / post 1992: 1.6 g per flush
    dual flush: should be mandatory
    high efficiency toilets: 1.28 g or less (save 22,000 g per toilet)
    go waterless….
    1.75 gpm or less (save 30% over std. 2.5 gpm)
    1.5 gpm low flow aerators (save 30% over std. 2.2 gpm)
    Garbage Disposals – DO NOT USE THEM…PLEASE…THINK …
    Clothes Washers (ENERGYSTAR)
    save 7,000 gallons of water a year / 11 year life of the washer, fills up 3
    swimming pools or provide a lifetime of drinking water for six people.

  • 10. epa community planning initiatives
    Nine planning steps:
    Specify Conservation Planning Goals
    Develop a Water System Profile
    Prepare a Demand Forecast
    Describe Planned Facilities
    Identify Water Conservation Measures
    Analyze Benefits and Costs
    Select Measures
    Integrate Resources and Modify Forecasts
    Present Implementation and Evaluation Strategy
    kingswood co., llc
  • 11. epa community planning initiatives
    The water conservation measures;
    Level 1
    Universal metering
    Water accounting and loss control
    Costing and pricing
    Information and education
    Level 2
    Water-use audits
    Pressure management
    Landscape efficiency
    Level 3
    Replacements and promotions
    Reuse and recycling
    Water-use regulation
    Integrated resource management

  • 12. case study – victor, Idaho
    Level 1
    generally in place for Culinary (Aquifer) Water
    Level 2
    Use Water Sense rated faucets + fixtures when you retrofit or build new
    Pressure Management
    Implement a City Wide Ordinance to incorporate pressure-reduction valves at the incoming meter to reduce wastage as a result of excess pressure
    Landscape Efficiency
    Prepare a guide to landscaping for Teton Valley which highlights native plant and grass species. Plant and grass selection is the first step, which must then be followed by a guide to watering during the summer months.
    We need to help people adjust their expectations with regard to landscaping.
    Initiate a guideline for max. % of irrigated grass per acre

  • 13. case study – victor, Idaho
    Level 3
    Replacements and Promotions
    Future program used to offset the cost of retrofits to switch out fixtures + fittings
    Re-Use + Recycling
    Grey water re-use for irrigation is common in many drier parts of the US.
    Water Use Regulation
    This is a tough one, but a common situation faced by many cities.
    Implemented over time, these sorts of regulations are adopted as habits by the community
    Implemented suddenly, these sorts of regulations can have controversial and litigious impacts
    Integrated Resource Management
    Already implemented through the Trail Creek Stakeholders Group coordinating the needs of Agricultural Uses; Residential Uses and City Uses. (Well done, FTR).

    DEQ's Pollution Prevention Program
    works with Idaho's businesses, communities and citizens to prevent pollution and conserve resources
    Contact DEQ for assistance on environmental issues related to air, waste, water, conservation, and sustainability

  • 15. d.e.q. initiatives
    Idaho GEMStars,
    a statewide pollution prevention (P2) excellence and recognition program. This program provides pollution prevention education and public recognition to businesses, agricultural operations, governmental agencies, school districts and others.
    P2 means reducing or eliminating pollution at the source so that it never enters the environment. This program's success relies heavily on the participation of entities that are concerned for Idaho's environment.

  • 16. top 5
    1. Stop Those Leaks!More than 10% of household water is lost due leaks.
    2. Replace your old ToiletIf your home was built before 1992 and the toilet has never been replaced, then it is very likely that you do not have a water efficient 1.6 gallon per flush toilet.
    3. Replace your Clothes WasherEnergy Star™ rated washers that also have a Water Factor at or lower than 9.5, use 35-50% less water and 50% less energy per load.
    4. Plant the Right Plants Having yard with 100% lawn turf area in an arid/semi arid climate uses significant amounts of water. Consider a more natural landscape or wildscape.
    5. Water Only What Your Plants NeedBe attentive if you are manual watering
    Make sure your irrigation controller has a rain shutoff device
