The Town has legal rights to 5.5 cfs of water from the Fraser River which has an average discharge for its 28 years of record of 195 cfs. The water of the Fraser River can generally be termed as very good, except that during periods of melt water run-off, the water becomes very colored and turbid. The water can be considered soft with a slight fluoride content and a high iron content. While the River is not presently considered infested with the organism Giardia 1amblia by the Colorado Department of Health, the possibility that it will become so infested, exists. The Colorado River at Hot Sulphur Springs is considered infested with this organism by the Health Department. , ' The present water system consists of an infiltration gallery in the Colorado River; raw water pumps, which lift the water from the River to the treatment facilities at the Municipal Building; treatment facilities, which consist of the addition of chemicals, pressure filtration and chlorination; a water distribution system, consisting of mail1s ranging in size from 2-1/2" to 12"; and a 235,000 gallon ground water storage tank. The intake facilities have a capacity of 3.5 cfs. The pumping and treatment facilities have a capacity of 1.5 cfs. The community presently uses the water at the rate of 0.4 cfs on the average day and 0.8 cfs on the maximum day. In the year 2000, the average and maximum rates are anticipated to be 0.8 cfs and 1.6 cfs, respectively. The treatment facilities, while generally doing a satisfactory job, does experience problems during the melt water run-off period. The operation is somewhat complicated in the way that the chemicals are presently being added to the treatment system. As a result, periodically color, turbidity and some taste and odors are associated with the supply water. 1-2
