.. .. ............. ....... . ...... ARDEN HILLS CITY COUNCIL—March 28, 2011 13 7.F. Resolution 2011-019: Award 2011 Sanitary Sewer Lining Project to Instuform Technologies, USA, Inc. of Chesterfield, Missouri, in the Amount of $399,444.50 (continued) Public Works Director Maurer stated the majority of the City's sewer mains were constructed in the late 1950's and early 1960's utilizing clay tile pipe. Over time, the joint materials have failed and allowed root intrusion. The pipe is also susceptible to cracking and construction damage. The 2009 Capital Improvement Plan includes funding for a sanitary sewer main lining program to extend the life of the City's sanitary sewers by 50 years or more. The sewer lining process has been proven over the past 20 years, and costs have become competitive. This technology also prevents infiltration of groundwater into the system and can be credited toward the City's inflow/infiltration surcharge. Staff assembled a specification and advertised for bids for approximately 3.14 miles of sewer main lining in areas identified as having root intrusion or infiltration problems. Based on past practice, the City Council would award the contract to the lowest responsible bidder. In this case,the lowest bidder is Instuform Technologies, USA, Inc., of Chesterfield, Missouri. The City has been awarded a Metropolitan Council Environmental Services (MCES) Municipal Inflow & Infiltration (I&I) Grant to fund 25% of this work. The balance of this project is to be funded in the Sanitary Sewer Enterprise Fund. The bid for this project is competitive and Staff recommends moving forward with the entire project. In order to fund the work over the budgeted amount, Staff recommends advancing dollars budgeted in the 2012 CIP for sewer lining. Mayor Grant asked for clarification regarding the grant amount and how much the City will be _ using of this grant. Public Works Director Maurer stated that based on the bid received,the City will not use all the $203,779 in grant funds that were received. The grant amount used for this project would be $99,861, which is the maximum grant amount that can be used to meet the 50% match on eligible expenses. There was approximately $25,000 of the grant used in 2010. The City will be using approximately $50,000 to $60,000 of the grant fund for manhole repairs and rehabilitations this year. The City is not able to go back and increase the amounts of work to be done on those projects that were submitted for the grant. The bids have come in lower than expected so the City will have grant funds remaining. Councilmember Tamble clarified the reason Staff wanted to do more this year was to maximize the amount of grant funds. Public Works Director Maurer stated this was correct. This grant was presented as a one-time offering and Arden Hills was the third largest recipient of funds. In order to maximize the amount of grant funds used the City could forgo projects in the future. Mayor Grant asked how many miles of clay pipe the City had remaining. Public Works Director Maurer stated there was approximately 17 miles of clay pipe remaining. MOTION: Councilmember Tamble moved and Councilmember Werner seconded a motion to Adopt Resolution 2011-019: Awarding 2011 Sanitary Sewer Lining,
