Steven Schwanke <br />January 25, 1993 <br />Page 4 <br />l/I currently would appear to be costing the City <br />approximately $90,000 per year in MWCC gallonage charges alone, but <br />significantly less in drought years. While capacity is not in <br />imminent danger of being exceeded, future capacity problems are a <br />potential if I/I is not further reduced. <br />City staff will be proposing to the City Council that the 1981 <br />I/I Analysis be updated to reflect current flow data, analyze the <br />extent, sources and possible solutions to the current I/I problems, <br />and identify and proceed with those solutions which are feasible <br />and cost effective. <br />As part of this update process, the City will initiate an <br />ongoing process to continually analyze flow data for City-owned <br />lift stations on an annual or semi-annual basis, comparing actual <br />flow data to the expected flow based on the number of units served <br />by each station, to identify problems as they occur. <br />Additionally, the City will initiate an inspection program to <br />eliminate the illegal discharge of roof water, groundwater, and <br />foundation drainage which may be entering the sewer system via sump <br />pump connections. Such discharges have been illegal in the City <br />since 1984 or earlier. <br />Finally, the City will provide an annual progress report to <br />the MWCC, indicating the extent of problems encountered during the <br />year and a running rec rd of actions taken to solve I,1 problems. <br />In regard to this Comprehensive Plan Amendment Nr. 3, please <br />contact me at 473-7357 if there is additional information needed in <br />order to complete your review process. <br />Sincerely, <br />Michael P.
