<br />e>J <br />~ <br />- <br />C'!' <br /> <br />(continued) <br />Today, TUcson Water supplies nearly <br />600,000 customers in an area covering 285 <br />square miles, More than 200 wells with a <br />capacity of 125 million gallons per day <br />pump about 100,000 acre~feet of ground~ <br />water each year. Urban, industrial, min~ <br />ing, and agriculture usage of groundwater <br />in the TUcson area is depleting this vital <br />resource 2.5 times faster than it can be <br />replaced. By 2025 the Groundwater Man. <br />agement Act will require that pumping be <br />reduced to a Safe Yield allocation-an <br />estimated 45,000 acrdeet per year. <br /> <br />c <br /> <br />Twenty years from now, Tucson <br />Water's service area population is pro~ <br />jected to reach one million The need for <br />water will double to 200,000 acre~ feet per <br />year. In 40 years, we'll need 300,000 acre. <br />feet per year-almost seven times what <br />we can safely pump from the ground, <br />Methods of meeting that great need are <br />being planned, including conservation <br />and the increased use of effluent, but the <br />vast majorIty of the water that Tucson <br />soon will need comes from the Central <br />Arizona Project. <br /> <br />(continued on page 6) <br /> <br />Tucson's water supply for the next 100 years will come from a variety of sources, the most important being the CAP. <br /> <br />Tucson Water Resources Plan <br />Phased Use of Water Sources to Meet Projected Demand <br />600 <br /> <br />500 <br />- <br />.,.. <br />1 400 <br />.,.. <br />::> <br />o <br />E 300 <br /> <br /> <br />- <br />... <br />... <br />1; 200 <br />'- <br />.... <br /><t <br />100 <br /> <br />4 <br /> <br />.
