REQUEST FOR COUNCIL ACTION Date: November 30, 2020 Item No.: 9.e Department Approval City Manager Approval Item Description: Approve Resolution Awarding Contract for 2021 Sanitary Sewer Main Lining 1 B ACKGROUND 2 The majority of the City’s sanitary sewer mains were constructed in the late 1950’s and early 1960’s, 3 utilizing clay tile and reinforced concrete pipe. Over time the joints have failed, allowing root 4 intrusion. The pipe material is also susceptible to cracking and construction damage. The City 5 began the sewer lining program in 2006 to rehabilitate the sewer mains and extend the life of our 6 sanitary sewers by 50 years or more. Lining technology essentially installs a new resin pipe inside 7 the original clay tile sewer main without digging up City streets, which results in minimal disruption 8 to residents during construction. The liner pipe is inserted into the main through existing manholes 9 and cured in place with a heat process. Each segment is typically completed in one working day. 10 Service line connections are reopened using a robotic cutter and remote cameras. During the 11 process, existing flows are bypassed using pumps. This technology also prevents infiltration of 12 groundwater into the main system and can be credited toward a Metropolitan Council Environmental 13 services inflow/ infiltration surcharge. 14 The 2021 Sanitary Sewer Main Lining Project includes lining for approximately 10 miles in areas 15 identified as having root intrusion or infiltration problems. Approximately 2.6 miles of the project 16 are within the City of Falcon Heights. The City of Roseville has executed a joint powers 17 construction agreement with Falcon Heights that includes this work. The City of Roseville will 18 invoice the City of Falcon Heights for any work completed within Falcon Heights. 19 The following seven bids were opened on November 10, 2020: BID TOTAL CONTRACTOR (Base Bid) Visu-Sewer, Inc.$1,144,602.25 Insituform Technologies USA, LLC $1,173,946.10 Hydro-Klean $1,176,035.10 S.J.
