City Council Regular Meeting Minutes July 28, 1998 Page 8 1 Mr. Janski stated they researched other options for I/I reduction with the intent to get more "bank 2 for the buck" being spent on the project. He noted the option to allocate remaining funds to an 3 incentive program, possibly providing $200 to $400 per house to switch over which would 4 encourage homeowners to take advantage of making changes. It may also be possible to 5 negotiate a bulk construction contract with a plumber to bid a package of homes at once. Mr. 6 Janski advised that even with an aggressive Sump Pump Inspection Program some backups may 7 still occur so the City may need to increase the sanitary sewer lines. 8 Mayor Ranallo asked if the City should do a feasibility study and then hold a work session with 9 all engineers to determine the best alternative. Mr. Janski stated the first step is to look at the 10 system and determine where the problems are. Mayor Ranallo stated he anticipated this would 11 be an issue. Mr. Janski stated the flow rates indicate most homes have some type of passive or 12 active inflow system. 13 Mr. Hubmer stated they would like to start the feasibility study now since they are also doing the 14 feasibility report on the street reconstruction.program and one of the areas preliminarily targeted 15 with sanitary sewer problems is 29th Avenue. This needs to be looked at during the feasibility 16 study. Thuesen asked if other communities have programs similar to this. Mr. Janski stated the City of Glencoe had a program to install sump pumps. In Glencoe, all connections were made the same 19 way but outside the homes via a manhole. They obtained a joint contract for 10 to 15 corrections 20 per year with the City paying the cost. 21 Cavanaugh asked if drain tiles were "standard operating procedure" when these homes were 22 constructed. Mr. Janski stated he thinks they were. Cavanaugh stated he has drain tiles in his 23 home but has not seen anything in it except for leaks by the downspout. He asked if there is a 24 way to determine which houses have a legitimate need for the drain tiles. Mr. Janski stated that it 25 is difficult to determine if the tiles cannot be observed. 26 Cavanaugh asked if the numbers are high outside of the flood issue. Mr. Janski stated that they 27 are high and explained that it can be confusing to residents since there are two sewer systems 28 involved, a storm sewer system and a sanitary sewer system. 29 Motion by Cavanaugh, second by Thuesen to order the feasibility study to determine the 30 feasibility and cost effectiveness of constructing physical improvements to the sanitary sewer 31 system and approve revisions to the Sump Pump Inspection Program as modified to include a 32 long-term program of reducing I/I directed at reductions in passive connections and sump pumps 33 and a short-term program of increasing sanitary sewer conveyance capacity to reduce basement 34 backups. •
