. SECTION V PROPOSED WATER SYSTEM DESIGN CRITERIA Wa~er used by the residents of the proposed district will vary from day to day; season to season; and year to year. These variations are due to weather conditions, influx of vacationers, changing population characteristics, and general development and growth of the District. The design criteria for the proposed water system must deal with quality of water, standards of construc- tion, and general reliability, as well as the quantity required to meet maxi- mum demands at various levels of District growth. The following Design Criteria will be used for various components of the pro- posed water system. Initial Water Requirements. The estimated maximum period design water re- quirements for existing development are approximately 70,000 gallons per day or 50 gpm during a peak day. Future growth could require a total supply of up to about 200,000 gallons per day. Existing development, assuming present useage patterns, would require a total diversion estimated to be 35 acre feet for a dry year. It is imperative that with new systems, during their initial formation stage, plans be made for phased growth so that large capital investments need not be made initially. This philosophy is important as to the general feasibility of a water district. The initial requirements were arrived at based on the number of homes and commercial and/or business structures in the Allenspark District. Included in the initial requirements are any growth which will be completed or pending completion at the time the water system is constructed and made operable. Water Quality. Minimum water quality design criteria are in accordance with Colorado State Health Department legal, bacteriological, physical, and chem- ical standards. Allowable bacteriological densities in the water supplied to users are prescribed by the State Health Department. Design Criteria should
