INTRODUCED: October 14, 2014 BY: Ed Brown COUNCILPERSON City Clerk’s Office Item # Q-4 Background Paper for Proposed Resolution COUNCIL MEETING DATE: October 14, 2014 TO: President Sandra K. Daff and Members of City Council CC: Sam Azad, City Manager VIA: Gina Dutcher, City Clerk From: Gene Michael, Wastewater Director A RESOLUTION AWARDING A CONSTRUCTION CONTRACT IN THE SUBJECT: AMOUNT OF $1,010,779 TO INSITUFORM TECHNOLOGIES AND SETTING FORTH $202,155.80 FOR CONTINGENCIES, FOR THE FY2014 SANITARY SEWER 30” ARKANSAS OUTFALL LINING PROJECT AND AUTHORIZING THE PURCHASING AGENT TO EXECUTE THE SAME SUMMARY: Attached is a resolution awarding a construction contract to Insituform Technologies for FY2014 Sanitary Sewer 30” Arkansas Outfall Lining Project on the 30” main running along the Arkansas River and the 38” main running down Prairie Ave. within the City of Pueblo. PREVIOUS COUNCIL ACTION : None BACKGROUND : The sanitary sewer system is comprised of several different types of pipe. One of these pipe types is reinforced concrete pipe (RCP) which, as time goes on, starts to break down. The surface of the concrete pipe will start to spall and peel off, eventually leading to corrosion of the RCP down to the reinforcement. Once the reinforcement starts to show, it too will become corroded. This is a good sign that the pipe is becoming closer to failure, leading to raw sewage being released into the ground and contaminating the ground water. In addition, if spalling and cracking occurs on the portions of the pipe where raw sewage is not flowing, infiltration of ground water can enter the sanitary sewer system. When infiltration occurs, selenium can also enter the sanitary sewer system. The EPA has strict limits on the amount of selenium that we are allowed to release after treatment, but selenium is very hard to remove. Therefore, if we can remove sources of selenium, we will have a cheaper, and easier, way to remove selenium. As long as the RCP is in good shape, the option of lining the mains with an impenetrable lining that will stop the entrance of ground water carrying selenium and cover the exposed and corroding reinforcement in the sewer main is best. The Wastewater Department maintains a priority list of these deteriorating sanitary sewer mains. The sites for this project were taken from that list due to their advanced deteriorated condition. To protect public interest, these mains require rehabilitation. The work by Insituform would involve installing an impenetrable liner known as cured-in- place pipe into a total of 6,162 lineal feet of 30” RCP and 1,300 lineal feet of 38” RCP. Private taps shall be reinstated to the sanitary sewer main using a tool inserted into the lined sewer main which will cut a hole through the liner at each tap. FINANCIAL IMPLICATIONS : The cost of the construction project will not exceed $1,010,779. Funds are available from the Sewer User Funds and have been budgeted and appropriated to Project #14- 066 (WWAN02). BOARD/COMMISSION RECOMMENDATION : Not applicable STAKEHOLDER PROCESS : None ALTERNATIVES : Alternative No. 1 – No Action Under this alternative, the City would do no improvements to the existing sanitary mains and the system would remain as is. Doing so could introduce unsanitary conditions to the public as well as contaminate ground water sources with raw sewage. Alternative No. 2 – Remove and Replace Sanitary Sewer Mains Under this alternative, the entire length of the 30” main and the 38” main would be excavated to remove all of the RCP and replaced with polyvinyl chloride (PVC) pipe. The amount of pipe that would need to be removed and replaced would be approximately 7,462 feet. This amount would include roughly 1,300 feet of 38” pipe. The remaining amount of pipe would consist of 30” pipe. Taps would have to be cut into the new PVC pipe at each tap location. There are approximately 9 taps that are feeding into the 30” and 38” RCP line. An increased amount for traffic control would have to be considered due to the fact that excavation in the roadway (Prairie Ave.) from Lee Ln. to Dittmer Ave. In addition, paving would need to be completed and flowfill would have to be added above the newly installed PVC pipe. The engineer’s estimate for Alternative No. 2 is approximately $2,200,000. RECOMMENDATION : Approval of the Resolution.
