Full Description

This powerpoint presentation presents the Phoenix (Arizona) Water Resources Acquisition Plan. Its strategic goal isto demonstrate the availability of sufficientsustainable water supplies to meet theCity's 2055 demands, considering a varietyof growth and drought scenarios. Thekey objective of the plan isoptimal water supply and infrastructureredundancy. Drivers include:growth- more aggressive projections, changing central city;drought- susceptibility to prolonged drought;acquisition challenges- higher cost and greater competition for new sources;assured water supply- must re-apply to ADWR before 2008; and,regional and institutional developments- Colorado River shortage negotiations, environmental/endangered species issues, andwater availability in non-metropolitan areas. Information is provided on supply/demand uncertainties, such as water consumption by acre feet from 1990-2006, wet/dry cycles of the Colorado and Salt River watersheds, Gallons Per Capita/Day (GPCD) Trends, Impact of Conservation on Water Use1980-2005, Spatial Distributionof Demand, and 50 Year Planning Uncertainties - 1951 Phoenix Population Projections and Actual Growth. Drought scenarios are presented by Length and Severity of Surface Water Shortages, and Growth and Water Use Patterns. Strategic concepts are presented and include: target demands between "base" and "high density"levels under moderate drought conditions; begin deployment of "future" supplies by 2015 to meetgrowth demands under moderate drought conditions; continue phased deployment of "future" and"supplemental" supplies beyond 2015 to meet growthdemands under normal, moderate and severe droughtconditions; supply selection will considercost,reliability,accessibility,maintenance needs,timing,quality and treatment, andpublic acceptance; funding fordeployment of futureand supplementalsupplies should bederived fromgrowth-relatedrevenues; and, promoteenhancedconservation tominimizedrought impactsto existing andfuture customers. Potential WRA Projects are listed.
