(5-0) Business from the Floor None REPORT OF VILLAGE ENGINEER DONALD CHRISTOFFERSEN Water Tower Needs Report Christoffersen introduced Engineer Liebenow (SEH) who is familiar with the Arden Hills and Roseville water systems; noted that Norm Hendrickson (SEH - now retired) prepared the 1984 report based on 1983 Arden Hills and Roseville records. Council was referred to Christoffersen's letter of 11/22/85, and Liebenow reported their findings, after review of 1984 and 1985 records from Arden Hills and Roseville, compared with the previous report. Liebenow explained that they compared peak days, August 6, 1983 to July 16, 1985, finding that the total amount pumped on 7/16/85 exc"eded the peak day in 1984 or 1983; reported that if Roseville should experience a complete power failure, its tank would be empty in 1-1/2 hours and the Arden Hills tank would be empty 8 hours, 20 minutes later. Liebenow noted that Roseville pumped 13,095,000 gallons to Arden Hills and Roseville on 7/16/85; Arden Hills' use that day was 1,990,000 and Roseville's tank reached a minimum volume at about 5:00 p.m. 0,217,000) . Liebenow noted from this comparison that the time it takes to empty the Arden Hills' tank has been reduced by 3 hours, 10 minutes from August 1983 to July 1985. In discussion of whether a 1 million or 1-1/2 million gallon tank is recom- mended, it was noted that this is a judgement call which is based on water demand and water usage experience. Christoffersen said bids can be taken on both tank sizes; noted that a 1 million gallon tank is considered the minimum; recommends the 1-1/2 million gallon tank if it can be secured at a reasonable cost; noted the determination of size is not an "exact science"; guidelines are based on averages, lawn sprinkler potential, usage experience, potential development. It was noted that the hourly consumption in Arden Hills on July 16, 1985 was about 40,000 per hour; a 1-1/2 million tank would provide the City with . about 18-24 hours of stored water. Woodburn noted that, at present, if a worse situation occurs, Arden Hills would be in an emergency situation in 7 to 7-1/2 hours. Hansen asked the feasibility of an emergency connection to an adjacent water supply. Liebenow said this has been done by other communities; said the adjacent community would have to be able to provide the water and Arden Hills able to receive it; noted that Shoreview does not have a lot of heavy water users across from our Lexington Ave. industrial area; consequently, probably does not have large mains. Arden Hills could feasibly have an emergency connection a block or so west of Lexington and obtain 3,000 - 4,000 g.p.m. at a given point. --
