Average Day Criteria <br />Generally, the minimum recommended standard, without fire protection, is equal to the average <br />day demand (Recommended Standards for Water Works, 1997 and adopted by the Minnesota <br />Department of Health). By this standard, a nearly 2,900,000 -gallon storage deficit is projected <br />for the year 2014 as shown in Table 3.6. <br />TABLE 3.6 <br />REQUIRED STORAGE BASED ON AVERAGE DAY USE <br />Year <br />Average Day <br />Demand <br />(mgd) <br />Average Day <br />Rounded <br />(gallons) <br />Existing <br />Storage <br />(gallons) <br />Storage Deficit <br />(gallons) <br />2004 <br />1.69 <br />1,700,000 <br />2,000,000 <br />+300,000 <br />2009 <br />3.89 <br />3,900,000 <br />2,000,000 <br />1,900,000 <br />2014 <br />4.93 <br />4,900,000 <br />2,000,000 <br />2,900,000 <br />2020 <br />6.18 <br />6,200,000 <br />2,000,000 <br />4,200,000 <br />Maximum Day, Fire Protection and Emergency Storage Criteria <br />Another approach is to consider the individual storage components needed for <br />equalization, fire demand, and emergency reserve versus the available water supply production <br />facilities. The water production and storage must be considered together, since an increase in <br />production may decrease the amount of water storage required. Water storage requirements <br />using this approach are summarized in Table 3.7. This approach demonstrates that by increasing <br />water supply, storage requirements will actually decrease. <br />City of Ramsey, Minnesota — M21.34343 Page 3-7 <br />Water System Study Prepared by Bolton & Menk, Inc. <br />
