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

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

  12. 12. case study – victor, Idaho<br />Level 1<br />generally in place for Culinary (Aquifer) Water<br />Level 2<br />Retrofits <br />Use Water Sense rated faucets + fixtures when you retrofit or build new<br />Pressure Management<br />Implement a City Wide Ordinance to incorporate pressure-reduction valves at the incoming meter to reduce wastage as a result of excess pressure<br />Landscape Efficiency<br />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. <br />We need to help people adjust their expectations with regard to landscaping. <br />Initiate a guideline for max. % of irrigated grass per acre<br />kingswood co., llc<br />12<br />
  13. 13. case study – victor, Idaho<br />Level 3<br />Replacements and Promotions <br />Future program used to offset the cost of retrofits to switch out fixtures + fittings<br />Re-Use + Recycling<br />Grey water re-use for irrigation is common in many drier parts of the US. <br />Water Use Regulation<br />This is a tough one, but a common situation faced by many cities. <br />Implemented over time, these sorts of regulations are adopted as habits by the community <br />Implemented suddenly, these sorts of regulations can have controversial and litigious impacts<br />Integrated Resource Management<br />Already implemented through the Trail Creek Stakeholders Group coordinating the needs of Agricultural Uses; Residential Uses and City Uses.

  14. 14. d.e.q. initiatives<br />DEQ&apos;s Pollution Prevention Program <br />works with Idaho&apos;s businesses, communities and citizens to prevent pollution and conserve resources<br />Contact DEQ for assistance on environmental issues related to air, waste, water, conservation, and sustainability<br />kingswood co., llc<br />14<br />
  15. 15. d.e.q. initiatives<br />Idaho GEMStars, <br />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. <br />P2 means reducing or eliminating pollution at the source so that it never enters the environment. This program&apos;s success relies heavily on the participation of entities that are concerned for Idaho&apos;s environment. <br />kingswood co., llc<br />15<br />
  16. 16. top 5<br />1. Stop Those Leaks!More than 10% of household water is lost due leaks.<br />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.<br />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.<br />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.<br />5. Water Only What Your Plants NeedBe attentive if you are manual watering <br />Make sure your irrigation controller has a rain shutoff device<br />Information courtesy of H2ouse.org<br />kingswood co., llc<br />16<br />
