CAP • Provides Water to Central and Southern Arizona • Is 336 miles long • Construction began in 1973 and is operated and maintained by the Central Arizona Water Conservation District (CAWCD) • Can Also Provide water to counties in New Mexico. • Provides approx. 44 billion gallons a year to tucson
Aquifers • Groundwater is where Tucson got most of its fresh water before the CAP. • But the pumping of groundwater is causing environmental problems. • The Land around the groundwater is sinking due to over draining
Blending • In 2006 Tucson was proposed a Blending plan to conserver water. • The plan is to blend groundwater with recharged Colorado River water. • The water will be mixed at a Clearwater Facility in Avra Valley. • If the plan is accepted by Arizona residents the mineral level will be set at no more than 450 mg/L , and more facilities will be built in Tucson to reduce the mineral content further. • With a possibility of raising it to 600 mg/L or even going lower than 450 mg/L
The Future • With the increasing population in Pima and Maricopa county the need for sufficient fresh water becomes a topic of major concern. • The Blending Program is aimed to provide water till at least 2050.
