    • Water Planningin TexasTemple McKinnon,Regional Water Planning
    • Water Planning: Legislative Response to Drought Late 1950s Drought of Record – 1957: Creation of TWDB – $200 million Water Development Fund – 9 State Water Plans, 1961-2012 Late 1990s: Potential New Drought of Record – ~$6 billion economic losses in ‘96 (mostly agriculture) – ~300 entities with threat to water supplies – 1997 & 2001: Passage of SB 1 & 2 which created & refined regional water planning 2

    • Regional Water Planning Project future population and water demands Quantify existing and future water supplies Identify surpluses and needs Evaluate and recommend water management strategies Make policy recommendations Adopt the plan Existing Projected Surplus Water Water (+) or Supplies Demand Need (-) 6

    • Water Conservation Savings Quantification Study Background Study was funded by TWDB Performed by BBC Research & Consulting Primary goal: Identify existing and potential ways of measuring implementation of conservation.
    • Published Information on Conservation in Texas – Key Findings• Increasing reliance on conservation to meet future needs.• Growing concern about lack of information on actual progress towards meeting goals.• Most assessments to date have focused on “effort” rather than “achievement.”
    • Top-Down vs Bottom-Up MeasurementTop-Down:Estimation based on aggregate water use changesBottom-Up:Quantification based on adding up savings estimates for individual conservation measures
    • Overall Findings Estimating actual water conservation savings is not a simple task, and Texas is not alone in struggling with this challenge Change in GPCD over time is a useful metric, but requires consistent data collection and adjustments for other factors affecting water use Comparison of GPCD between providers is not helpful in assessing conservation savings Providers currently use a variety of methods to estimate savings, with top down (GPCD-based) approaches being the most common
