ME T ROPOLiTRn <br /> WAITS <br /> COnTROL <br /> commitlion <br /> ckies Rrea <br /> February 22, 1982 <br /> All <br /> Mr. David Childs, Manager <br /> City of St. Anthony <br /> 3301 Silver Lake Road <br /> Minneapolis, MN 55418 <br /> RE: St. Anthony Wastewater Flows <br /> Dear Mr. Childs: <br /> This letter is a follow-up of the meeting between the Commission and- the City <br /> of St. Anthony. In re-examining the flow measurements, calibration records, <br /> and other available data, the Commission. is confident of the -accuracy of Meters <br /> 55 and 104. The Commission will continue to service, calibrate and monitor <br /> the performance of these meters. <br /> As indicated in our meeting, Meter 55A has-.a potential maintenance problem and <br /> has not been in operation long enough to establish a performance record. With <br /> the City's cooperation in providing maintenance of the diversion, limits on <br /> the meter performance can be established. These limits will assist in determin- <br /> ing meter failure and the frequency of service and calibration. The Commission <br /> will pay close attention during 1982 to Meter 55A to determine performance <br /> limits. <br /> Concerning estimates of unmetered flow, it is the Comihission's understanding <br /> that 69 unmetered residential sewer services currently exist. As such, the <br /> Commission will adjust the 1982 final cost allocation to reflect a 23 million- <br /> gallon credit to the City of St. Anthony. This adjustment accounts for the <br /> overbilling of unmetered areas for 1976 through 1979, as presented in the PDR's <br /> memorandum. Adjustment, for 1980 has already been made. To prevent any future <br /> misunderstandings, the Commission will assume that 69 unmetered sewer services <br /> exist and that each residential connection contributes 100,000 gallons per year. <br /> If the number of unmetered connections change, the City should report the <br /> change on the Sewer Survey Form sent to the Commission on an annual basis-. <br /> We look forward to submittal of your infiltration and inflow study. If you <br /> would like a revised 1982 Estimated Billing or should you have any further <br /> questions, please contact the Commission. <br /> Sincerely, <br /> R. A. Odde <br /> Community Services Manager <br /> • cc: R. L. Berg, MWCC <br /> M.
