Residential surveys Plumbing retrofits Landscape surveys and conservation incentives Ultra Low Flow Toilet (ULFT) rebates efforts within the BAWAC region. Areas selected for comparison provide a range of characteristics relevant to the BAWAC region: • Geographical location (western, with history of drought) The projected water savings for the BAWAC region will come from a variety of measures, including: • • • • Nevada/Las Vegas) to demonstrate the progress of water conservation • Climate (coastal/Mediterranean/arid mix) • Efficient washing machine rebates • Commercial and industrial surveys and conservation incentives • Public outreach and educational programs • Population density • Size (Population from 0.8 – 5.5 million) As conservation efforts intensify, some flexibility to further reduce water use in dry years is lost.
