Document Summary

Water use in north america the united states= 2nd; canada=4th. Pressures on freshwater resources: climate change, pollution, population growth, resource extraction. ^ demand for water & water treatment: ^energy use & ghg/pollutants. Need ^ infrastructure capacity: ^ infrastructure capacity =>^$ (construction, monitoring, treatment,maintenance, ^$=^tax. Discounted prices=less $ to maintain or repair system. Equity issues with metering & raising prices. New wells, deeper wells, diversions=unsustainable: easiest =exploited first & less , remaining =difficult to access & ^$ Demand-side management: less h2o through changing behavior/technology improvements: benefits: less$/treatment requirements/pressure to ^capacity. Recycling water can reduce wastewater generation/energy input/treatment required: plan from the future back to the present: traditional approach to planning begins in the present and forecasts into the future identify policies =>desirable end. Voluntary: water efficient demonstration garden: educate the public about technology and techniques. Technology: drip irrigation, weather-based irrigation, capture systems for rain and runoff, permeable surface materials. Techniques: drought tolerant landscaping, mulching: education programs for landscape contractors and homeowners.
