Show problems were reported by consumers, and at the present time this approach to developing Jordan River water has been discontinued. There are, however, other methods by which Jordan River water could be developed. Secondary water systems could deliver Jordan River water for commercial and industrial and other non- culinary uses such as watering large grass areas, ( i. e. parks and golf courses). This approach could reduce the amount of treatment required to meet culinary water needs and is being used to some extent by several cities. The capital expense of building an infrastructure to deliver secondary water would be considerable, and should be weighed against the cost of other alternatives. Jordan Narrows Pumping Station Another approach would be to use more advanced water treatment methods to treat Jordan River. Current state of the art treatment methods could be employed to render Jordan River water drinkable. These methods, however, are expensive ( 400- 500 dollars per acre- foot) and could result in a significant cost increase to the water users. Still another approach for the development of Jordan River water would be to buy Jordan River 9- water rights, then leave the water in Utah Lake and transfer the water right to groundwater withdrawals in Utah County. While this approach is hydrologically sound and would probably meet with approval from the State Engineer, it would likely meet with stiff opposition from water user's in Utah County. 9.5.2 Develop Additional Water from Wasatch Range Streams The development of additional water from the Wasatch Range streams holds a limited potential for addressing the future needs. Plans in place to enlarge some of the water treatment facilities and put more of this high quality water to culinary use. Further development of these streams, however, is a very sensitive environmental issue. A significant quantity of high quality water flows from the mountain streams to the Jordan River and subsequently to the Great Salt Lake. The average annual flow into the Salt Lake Valley from Wasatch Range streams is 173,400 acre- feet. At the present time, approximately 68,000 acre- feet of that water is incorporated into public water supplies. Existing plans to enlarge and improve the management of existing water treatment facilities would increase this amount to 91,640 acre- feet. That still leaves a significant quantity of high quality water that could be developed from the Wasatch Range streams. It is estimated about 75 percent of the flow from these streams ( about 130,000 acre- feet) comes during the spring runoff period from mid- April through mid- July. To fully develop this high quality water for culinary use, it will be necessary to either construct reservoir storage or provide treatment plant capacity equivalent to the peak runoff. The feasibility of reservoir construction on Wasatch Range streams and within the Salt Lake Valley has been investigated. The Salt Lake County Area- Wide Water Study conducted jointly by the Metropolitan Water District of Salt Lake City, the Salt Lake City Corporation, the Salt Lake County Water Conservancy District and the Division of Water Resources in 1982, identified several potential reservoir sites in the Wasatch Range canyons as well as various locations within Salt Lake Valley. At the present time, however, it is widely held that for political, economical and environmental reasons, the construction of additional reservoirs within the Jordan River Basin is not a viable option. Without additional surface reservoir storage, the |
