The City of Tucson has implemented a reclaimed water reuse program in a community-wide effort to preserve high quality groundwater for potable and other priority uses. Presently, the system consists of an 8. 2 million gallons per day (mgd) pressure filtration plant (expandable to 25 mgd), a 3 million gallon reservoir, a 12 mgd booster facility, and a significant network of large capacity distribution lines which supply major turf irrigation uses throughout the community. An additional element of the system is a 1. 0 mgd aquifer recharge facility which provides cost effective seasonal storage of reclaimed water for subsequent recovery and use during the peak demand season. The initial system was made operational in February, 1984 with the first deliveries of reclaimed water for turf irrigation. By the end of fiscal year 1986-87, Tucson Water will be providing nearly 5,000 acre feet per year of reclaimed water with the expanding reclaimed water system. Additional aspects of the system are discussed.
