This is the first update to Water Plan: 2000-2050 since it was issued in 2004. The substantive issues and challenges to ensuring a secure water future for our community remain largely the same and are discussed at length in the original Water Plan: 2000-2050. However, the planning timeframes within which to address these challenges have changed and are discussed in this Update. This Update also accounts for revised population projections that have since been developed, an increase in the City's Central Arizona Project allocation, and changed planning assumptions and priorities which have evolved in the last three years.

Both the original water plan and the update clearly demonstrate that the community served by Tucson Water has the water resources available to provide a long-term, sustainable water supply. This supply is sufficient not only for Tucson Water’s current residents but also for those who are projected to come in the next several decades. As a result of new water distribution systems, the community’s remaining water resource challenges primarily involve increasing system reliability and securing sustainable water supplies for new growth in the decades beyond. 

Both  Water Plan: 2000-2050 and this Update clearly demonstrate that the community served by Tucson Water has the water resources available to provide a long-term, sustainable water supply. This supply is sufficient not only for Tucson Water’s current residents but also for those who are projected to come in the next several decades. Tucson Water’s rate payers have already invested in developing the Utility’s water-resource portfolio and its extensive water distribution systems. As a result, the community’s remaining water-resource challenges primarily involve increasing system reliability and securing sustainable water supplies for new growth in the decades beyond.
