Tucson Chapter October Meeting Summary
Ralph Marra and Wally Wilson, of Tucson water, spoke at the October meeting.
Tucson Water staff presented the Utility’s 2008 Update to Water Plan: 2000-2050; the latter was originally issued in 2004. The focus of the update was to re-evaluate future water demand based on new projections and revised assumptions and to reassess critical planning variables which could impact meeting that demand.
Citizens of Tucson had long relied on the use of groundwater to meet their water needs. The plan is to continue to shift the City of Tucson away from its historical reliance on mining groundwater through the increasing use of renewable supplies such as Colorado River Water, Central Arizona Groundwater Replenishment District water, effluent, and potential future additional sources as well as by expanding its conservation/ demand management programs.
The 2008 update accounts for anticipated changes in population and therefore to demand projections through 2050. The 2008 update also notes increases in the City’s CAP allocation, expanded reclaimed water facilities, local and regional drought effects and possible shortage declaration on the Colorado River in the near to mid terms, potential for climate change in the longer term, and many other uncertainties. What became clear is the priority Tucson Water places on continuous planning and why the maximization of flexibility is so highly prized when contending with change and future uncertainties.
