In addition, an estimated 10,000 acre- feet per year is brought into Salt Lake County from Tooele County by Kennecott Utah Copper for self- supplied industrial use. 5.4 Present Water Use Water use can be separated into two general categories: potable and non- potable. Potable water satisfies most municipal and industrial demands while non- potable water supplies irrigation to agricultural lands and some residential lawns and gardens ( secondary) and wetland areas. The present water use for the Jordan River Basin, potable and non- potable, is compared with the existing water supply in Table 5- 7. Potable water is divided into three water supply categories: public water systems, private domestic systems and self- supplied industrial. Public water systems deliver water to cities, towns and subdivisions. They are regulated by the Division of Drinking Water ( See Section 11). Private domestic systems are individual residences not served by any 5- 7 |
