User demand information submitted in the plan shows that 71% of the demand is residential, -13% comm rcial, <br /> 4% instimflonal and 0% industrial. The city also has 12% of its pumped water in an "unaccounted" category <br /> that includes 3.3 million gallons of unmetered public use (filter backwash for 10 filters, hydrant flushing). <br /> This percentage exceeds the recommended maximum of 10%, and suggests tha't a water audit program could <br /> help the city "recover" some of this lost water, especially from public uses that could be metered. The city <br /> notes its difficulty in meeting the 10% level, and references problems with older pipes and unauthorized or <br /> unmetered use of hydrants. The city does have long-range programs for waterm-ain replacement.when roads <br /> are replaced, and for meter replacement at both the residential and commercial levels. <br /> The only large volume customer, comprising about 7% of 1994 demand, is Equinox Apartment Complex <br /> (commercial account). <br /> The existing facilities discussion in the plan was supplemented by information sent in later by the city. The <br /> water system is currently fed by three Prairie,du Chien-Jordan Aquifer wells rated at a capacity of 1200 <br /> gallons per minute (gpm)each, for a total of 3600 gpm(equivalent to 5.18 mgd). Please note that the 1200 <br /> gpm rate differs from the rates listed in the Minnesota Department of Health forms accompanying the plan <br /> (pages 5 and 6). The plan reviewer will assume, unless otherwise notified, that the rates reported as part of <br /> the plan are the correct ones. The firm capacity, or capacity available if the largest pump is out of service, <br /> would be 3.46 mgd, or approximately twice the maximum daily demand. The city has 2.25 million gallons <br /> of storage available in two storage facilities. The f=capacity and storage are four times and over two times <br /> the average daily demand, respectively. No new pumping or storage facilities are planned by the city. <br /> The TCAAP situation described earlier resulted in the addition of activated carbon filtration to the city's water <br /> treatment system. The city's permanent carbon filtration plant was put on-line in 1990 with money made <br /> available from Superfund. This,addition resulted in double filtering, since the water is also filtered for iron <br /> removal. The total treatment capacity of 5 mgd matches the capacity of all three wells pumping at maximum <br /> levels, and.is five times the average daily demand. <br /> An analysis of winter demand versus summer demand shows that summer use exceeds winter by about 0.35 <br /> mgd. Record peak usage in the city was 2.169 mgd in June of 1988 during the last major drought. This <br /> amount of summer demand over winter demand is relatively low and reflects the mature nature of the <br /> landscape and the lack of need for irrigation to establish new landscape. It does, however, suggest one-area <br /> where the city could focus its conservation efforts. <br /> St. Anthony Village recently emerged as number 21 on the Minnesota Department of Health(MDH)list of <br /> priorities for wellhead protection plans. The city indicates that it is working with the Hennepin Conservation <br /> District on a wellhead protection plan in advance of any state requirement to do so. Details on the wellhead <br /> effort were not included in the plan because of the preliminary nature of the effort. <br /> Part TT- Fmergrnry Planning(OberMEM <br /> The emergency portion of the plan is difficult to ascertain from the rest of the plan at first glance. IlLis could <br /> be critical in an emergency when time is of the essence. It is suggested that the final plan adopted by the city <br /> assemble all of the emergency information in a single section, and tab that section or place it in an appendix <br /> for rapid location. <br /> The emergency plan begins with a description of the interconnection that St. Anthony has with the St. Paul <br /> Water Utility via Roseville. Because the St. Paul system is predominantly a surface water source, this <br /> connection supplies St. Andiony with an alternate source of water to the Prairie du Chien-Jordan Aquifer that <br /> supplies its wells. This back-up availability is a very good emergency component to the system in the event <br /> of aquifer contarnination. 1he Roseville connection could serve about one-half of the needs of St. Anthony <br /> in an emergency, and was in fact used in 1986. In order to use the Roseville connection, the city must first <br />
