CITY OF LITTLE CANADA <br />RAMSEY COUNTY, MINNESOTA <br />Office of: <br />JOSEPH G. CHLEBECK, Clerk <br />515 Little Canada Road <br />Little Canada, Minn. 55117 <br />484 -2177 <br />Feb. 18, 1982 <br />MEETING ON WATER LOSS <br />Present were: <br />Karl Streed St. Paul Water Department <br />Ewald Biese Carley Engineering <br />Joseph Chlebeck City of Little Canada <br />Roger Glanzer City of Little Canada <br />MAYOR <br />Raymond Hanson <br />COUNCI L <br />Michael Fahey <br />Beverly Scalze <br />Dennis Forsberg <br />Mugs Nardinl <br />There are three basic areas where water can be lost: The wholesale meter, <br />water mains & services, and retail meters. <br />Wholesale meter will be tested by the St. Paul Water Dept. This will be <br />a reservior draw down test, in this test, Little Canada will draw water <br />from St. Pauls reservior with all other services closed. The amount of <br />water pumped out of the reservior will be calculated, and compared to the <br />reading on the meter. If the meter is accurate, the readings will be <br />the same. <br />Water loss in our Distribution System can bedetected by taking the <br />average hourly flow rate in 24 hours and the average hourly low flow <br />rate (between the hours of 1 and 3 a.m.) The average hourly low flow <br />rate should be a very low percentage of the average hourly flow. If <br />the percentage is high this indicates that there is a line loss or a <br />high water user during the low flow period. <br />Water loss can result from slow registering retail meters. <br />Other possibilities that were discussed were: Ice build up in the <br />• 24" main near the meter, that would distort the meter reading. <br />Remote readers could be off from the meter inside the house. <br />Gate valves that have to be closed so that the water will not run <br />back into St. Pauls reservior. <br />Respectfully submitted, <br />Roger Glanzer <br />Superintendent of Public Works <br />RG:gb <br />
