2008 Update to Water Plan: 2000-2050

This is the first update to Water Plan: 2000-2050 since it was produced in 2004. 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 time frames to address these challenges have changed and are discussed here. The Update also accounts for revised population projections, an increase in the City's Central Arizona Project allocation, and changed planning assumptions and priorities since 2004.

Download the entire 2008 Update to Water Plan: 2000-2050 or the individual chapters and articles as smaller, individual pdf files.
