General <br /> <br /> <br />Municipal water 5upply systems are designed to .satisfy demands of <br /> <br /> <br />different magnitudes occurring at different times and for different <br /> <br /> <br />durati ons. These demands are generally th05e desc ri bed as annual raw <br /> <br /> <br />water requirement, 'naximum day requirement, and maximum hour requirement. <br /> <br /> <br />The annual raw water requirement is met by diverting and storing raw <br /> <br /> <br />water under existing State Water Laws and del ivering amounts needed from <br /> <br /> <br />these facil ities to the treatment facil ities. The maximum day <br /> <br /> <br />requirement is met by providing: adequate raw water supplies, adequate <br /> <br /> <br />treatment capacity, and adequate distribution facilities. The maxililum <br /> <br /> <br />hour requireme~t is met by providing adequate treated water storage and <br /> <br /> <br />adequate di5tribution facilities. Fire flow requirements are generally <br /> <br /> <br />met by providi ng storage to provide the vol ume of water needed and a <br /> <br /> <br />distribution system capable of conveying the necessary flow rate and for <br /> <br /> <br />the duration required. Some of the factors affecting demands include per <br /> <br /> <br />capita use, population, climate, cost of water, pressure fluctuations <br /> <br /> <br />within the distribution 5ystem, ratios of different types of uses, 50cial <br /> <br /> <br />attitudes, system losses, and unmetered municipal water uses for cleaning <br /> <br /> <br />pUblic facil ities such as streets and sewers. In this study, tile raw <br /> <br /> <br />water supply require~ents are based on projected population Figures <br /> <br /> <br />coupled with per capita water supply requir~nents. These figures <br /> <br /> <br />represent the most current available infonnation as of the date of this <br /> <br /> <br />re port. <br /> <br />-15- <br /> <br />r <br />
