<br />.- << <br /> CITY OF ARDEN HILLS <br /> . MEMORANDUM <br /> DATE: January 12, 1996 <br /> TO: Brian Fritsinger, City Administrator <br /> FROM: Dwayne Stafford, Public Works Superintenden <br /> SUBJECT: Water System Modifications <br /> Back!!round: <br /> The City of Arden Hills currently has two water towers, our south tower, a one million gallon <br /> tower south ofInterstate 694 on Red Fox Road and our north tower which is north ofInterstate <br /> 694 on Fernwood Avenue. The Arden Hills south water tower is filled by Roseville pumps when <br /> water level sensors instruct the pumps to come on, The Arden Hills north tower is filled by <br />- Arden Hills booster station pumps, when instructed, which draw water from the same lines that <br /> fill our south tower. Up until this past summer the City had never been able to completely fill <br /> the south tower. <br />- <br /> During the past summer while Roseville was painting its water tower, Arden Hills opened by- <br /> . pass valves between Roseville's system and Arden Hills's system, allowing un-metered water to <br />. flow back and forth between the cities. Thus, enabling Roseville to share our south water tower. <br /> Working with Barney Brion from Roseville Public Works Department and implementing the <br />- following ideas, staff was able to overflow the south tower and keep it full of water all summer. <br /> 1. The pressure regulating valve between north and south sides of the City was found to be <br />- defective and was then closed. This problem alone could account for 2 to 3 pounds of <br /> pressure loss, which would translate to 4 to 7 feet in tank water elevation. The valve has <br /> since been modified, by Arden Hills Public Works staff to work only manually. <br />- <br /> 2. There are two (2) 12 inch and one (1) 16 inch feeder lines from Roseville serving Arden <br />- Hills. All of these feeder lines are reduced down to 8 inch meters at Arden Hills three (3) <br /> metering stations. The by-pass valves were opened all summer allowing water to enter <br />- the City, unrestricted by meters. <br />- <br /> , Obsolete and unreliable telemetry to Roseville has since been upgraded to a state of the <br /> -'. <br />- <br /> art system. <br />- <br />- <br />-- <br />- - . <br />- <br />- <br />- <br />
