Abstract |
The city of Tucson, Pima County, Arizona, and agricultural interests in the Avra Valley have an opportunity to work together for their own benefit and that of the entire community. University of Arizona Water Resources Research Center and the Agricultural Engineering Department have proposed a plan for treated waste water produced by the Tucson metropolitan area to be allocated to farmers in the Avra-Marana area in exchange for groundwater now used for irrigation. The waste water would be used only on land presently under irrigation. The same distribution system built to carry treated municipal waste water could be designed to carry a mixture of CAP water and waste water to the irrigated areas of Avra Valley. |
