EXISTING WATER USAGE <br /> <br />1. General Information on Water Usage. <br /> <br />In correlation with accurate population estimates, <br />estimating existing and f~ture water per capita use <br />is an important aspect ofjwater systems analysis <br />planning and design. It is essential for accurate <br />capacity analysis of existing facilities and for <br />predicting capacity requitements of future <br />expansions. <br /> <br />Water use can be divided into several categories, as <br />follows: <br /> <br />a. Domestic use. Includ$d in this category are all <br />inside uses for resid,ntial, commercial, public <br />and institutional buildings. <br /> <br />b. Irrigation use and stock watering. <br /> <br />c. Industrial uses for manufacturing. <br /> <br />d. System losses, including operational usage, <br />leakage, and wastage. i <br /> <br />Water use in a community such as Norwood is <br />influenced by a number ofifactors. The most <br />important will be climatic conditions, economic <br />level of the residents, cost of the water, <br />availability of non-potable irrigation water, size <br />of lots and parcels, and the type and magnitude of <br />residential and industrial development. There are <br />no known industrial manuf~cturing plants or food <br />producing plants in the atea. Thus, all water use <br />should fit into domestic, !irrigation and system <br />losses. <br /> <br />All communities show a substantial variation in <br />water use on a seasonal, daily and hourly basis. <br />Peak hour use is used to size water pipes; maximum <br />day use is used to size water treatment plants and <br />storage tanks; monthly and seasonal water use is <br />used to determine capacity for raw water storage <br />rf'servoirs. Although thi$ report is concerned <br />pt'imarily with winter time water usage, year around <br />'13e also will be evaluated since water rights are <br />-'merally based on total annual use. <br /> <br />2. ,.\asis For Flow Data. <br /> <br />Flow data was taken from the preliminary Engineering <br />report prepared by WestWater Engineering in <br />November, 1991, For that:report, 35 months of water <br />
