• MEMORANDUM DATE: February 17 , 1982 TO: Dave Childs , City Manager FROM: Larry Hamer , Public Works Director SUBJECT: Inflow and Infiltration Study -------------------------------------------------------------------- The I/I study has been completed and copies have been submitted to the State of Minnesota and Metropolitan Waste Control Commission for their review. I would be happy to discuss any portion of this docu- ment with anyone who wishes to do so. In conjunction with the study , we are still televising the sanitary sewer lines . It will take two to three more years of televising to get a full picture of the City ' s problems with the I/I and to determine whether it would be cost effective to correct ome cr all of the infiltration. • According to Planning , Design &Research 's study , it would not be cosy effective to remove the inflows (drain tile) . I feel the work done on the I/I study was very informative and left me the impression that the City should establish a semi-annual program of checking Metro Waste ' s metering and charges for disposing the ,waste . The latter should be checked because Metro Waste does not change the charges to the City and unless we keep abreast of changes such as population , decline in water consumption , dry weather , ^. , the City could be overcharged. The MWCC meters the waste , h6 .ever , they often estimate when they suspect meter malfunctions . The City has received most of the Federal grant money for the study and upon submission of the study to the State , the State grant money will be paid to the City. The grant money will total 900 of the cost of the study , the City ' s portion will be 100 . The final bill from Planning, Design and Research has not been submitted as of yet , but I anticipate receiving it soon . The total cost is not to exceed $24 , 500 . 00 .
