Reducing consumption
Tucson is situated in the Sonoran Desert with few natural water resources. It receives 300mm or less of rainfall per year. piddle supply has been an issue for over 100 years
Mules used in 1800s
Then wagons
Then Tucson Water Co. from 1881 using groundwater and piping it
Tucson Water Co came under city control from 1900.
A growing city = growing penury and the city has a long range plan 2000-2050 to mark supply and demand.


New storage capacity.
Reservoirs dont count feasible in this arid area. 48 reservoirs exist scarcely mainly to store carbon monoxide river water (delivered by the CAP) which in turn allow water to percolate and recharge the groundwater levels in aquifers.

Water transfers.
Colorado River Water

Tucsons portion of Colorado River water, about 44 billion gallons each(prenominal) year, comes to us through the Central Arizona Project canal. We before long use about 20 billion gallons of Colorado River water a year. Most of this supply is put into specially constructed basins in Avra Valley at the Clearwater Facility.



Here the water sinks into the earth (recharges) and blends with the immanent groundwater beneath. This blend is then recovered by a make out of wells and piped to the Tucson Water distribution system.
The use of this blended water has let us reduce our reliance on groundwater. Tucson Water has put a number of wells in substitution Tucson on standby, allowing our water table to begin recovering from decades of over-pumping. As part of Water Decision 2006, Tucson Water customers will take to decide how we will use the remaining portion of our Colorado River water and of what quality we want that water to be when it is delivered to us.
Groundwater sources.
