AR- DEN HILLS CITY COUNCIL—August 10, 2009 4 A. Motion to Award the 2009 Sanitary Sewer Lining Project to Visu- Sewer, Inc., of Pewaukee, Wisconsin, in the Amount of$44,960.50 Civil Engineer Kristine Giga stated the majority of the City's 42 miles of sanitary sewer mains were constructed in the late 1950's and early 1960's, utilizing clay the pipe. Over time the joint materials have failed allowing root intrusion. The 2009 Capital Improvement Plan includes funding for a sanitary sewer lining program to extend the life of the City's sanitary sewer by 50 years or more. This technology essentially installs a new resin pipe inside the old clay the sewer main without digging up City streets, which results in minimal disruption to residents during construction. This technology also prevents infiltration of groundwater into the system and can be credited toward the City's inflow/infiltration surcharge. The location for the sewer lining project was reviewed and a map was provided to the Council. There is approximately 1,100 lineal feet of sewer main lining in the areas identified as having root intrusion or infiltration problems. This project would be funded using funds from the Sanitary Sewer Enterprise Fund. Councilmember Holden stated that the budgeted amount for this project was $75,000. She asked if there had been an engineering estimate or where the cost estimates had come from for the budget amount. Civil Engineer Giga stated that the engineering estimate was based on costs received last year. The prices from last year were higher than the current prices. Councilmember Holden asked if there were additional sewers that could be lined - since the costs were favorable. Civil Engineer Giga stated that Staff is looking into this. The contract with Visu- Sewer can only be increased by 25% of the contract amount or 250 feet and Staff is trying to locate an area that fits this criteria. Staff is also talking to Visu-Sewer to see if they would be amenable to adding to the project. Councilmember Holden stated that Staff could put another area out for bid if there are additional areas that need to be done. Civil Engineer Giga stated that Staff could look at doing this as well. Mayor Harpstead clarified that the recommendation from Council would be to put together another project for bid or work with Visu-Sewer to increase the amount of the contract.
