33

34 Bloomington System Improvements: Project 8084 Description: This project provides for a new Lift Station L-55 in the City of Bloomington. It also includes interceptor expansion as needed. Purpose and Justification: Lift Station L-55 is in need of replacement based on a condition assessment and capacity requirements. This project is located in the City of Bloomington.

35 Blue Lake Plant Improvements: Project 8018 Description: This project consisted of replacing the existing gaseous chemical effluent disinfection system with liquid chemical disinfection; modifying the existing secondary treatment facilities to remove phosphorus to meet the 1 mg/l annual average limit; rehabilitation of facilities nearing the end of their useful life; improvements to the solids processing facilities and odor control; the addition of anaerobic sludge digestion to supplement the existing sludge dryer for reliability and to recover energy for dryer use; and improvements to plant utility systems. Construction of these improvements is nearing completion. The original project included the staged expansion of the plant's capacity. That phase of the project has been postponed to a later date and was removed from this project. Purpose and Justification: In addition to meeting the regulatory requirements of the NPDES permit, the improvements provide increased process reliability and energy recovery.

36 Blue Lake System Improvements: Project 8028 Description: This project will provide improvements to meet the long-term conveyance capacity, reliability, and rehabilitation/replacement needs of the Blue Lake Interceptor System. This system includes gravity sewers, 29 lift stations, and single forcemains from each lift station. Where cost effective, such as in the Victoria area, some lift stations will be replaced by deep gravity sewers using tunnel construction methods. In some cases, small lift stations will be consolidated. The remaining lift stations will be rehabilitated and/or replaced as necessary. Single forcemains will be upgraded to dual forcemains. Gravity sewers will be rehabilitated as necessary. The five major project areas are Victoria, Excelsior, Mound, and Wayzata, and Gravity Sewers (Chanhassen, Eden Prairie, Minnetonka, Prior Lake, and Shakopee). Purpose and Justification: Evaluation of the Blue Lake Area Interceptor System indicates that the existing facilities cannot convey all of the wastewater that will ultimately be generated from within the Blue Lake sewer shed. In addition, many of the sewers, lift stations, and associated forcemains need to be rehabilitated to ensure system reliability and to address odor and corrosion control.

37 Brooklyn Park LS/FM Improvements: Project 8079 Description: This project will provide two new forcemain pipes from L32 in Brooklyn Park to existing pipes in Fridley by river crossing. Improvements to the lift station and rehabilitation of the existing forcemain pipes and downstream gravity sewers are also included. Land acquisition for the site of a future relocated lift station is also included. Purpose and Justification: On June 21, 2012 a forcemain break was reported on the MSB 69U1 forcemain (Lift Station L32) river crossing. The spill occurred on the east bank of the Mississippi River in the City of Fridley within the Girl Scouts Campground. An emergency situation was declared and Lametti and Sons (contractor) was mobilized to the site to repair the break. The leak was located on the north barrel of the two barrel forcemain; above the bottom 45 degree elbow as the forcemain rises up the east bank of the river. Examination of the failed pipe reveals that the failure occurred as a result of pipe wall erosion caused by continuous scoring by gravel and sand trapped and unable to make it up the incline (insufficient flow velocity). The south forcemain barrel is likely in similar condition; and with it being the remaining active barrel it is possible a second break might occur. The 2012 repairs were considered temporary. This project provides for the long-term replacement of the river crossing forcemain facilities.

38 Chaska Lift Station: Project 8039 Description: The project consists of the design and construction of a new larger pumping station at the former WWTP site to provide long-term capacity to serve Chaska and Carver. The project includes the demolition of wastewater treatment facilities from the phased-out Chaska WWTP. Purpose and Justification: Without the project, the projected development within the Cities of Chaska and Carver will cause wastewater flow to exceed the present interim lift station capacity by 2016.

39 Elm Creek Corcoran/Rogers Connections: Project 8085 Description: Under the original Elm Creek Interceptor family of projects (Project 9004), the Metropolitan Council administered the construction of 12 miles of the main stem of the Elm Creek Interceptor. Eight of those miles extend from the CAB Interceptor in Brooklyn Park ((101st Ave N and Noble Ave) westerly to I-94 and CSAH 30 in Maple Grove (Phases I & II and Trench Sheeting). The other 4 miles are located between Elm Road in southern Maple Grove and across northwest Plymouth to Hamel in the City of Medina (Medina Leg). Under a cost-sharing agreement, the City of Maple Grove constructed 4.5 miles of the main stem linking these two Council interceptor segments, paralleling Elm Creek between I-94 southwesterly to Elm Road. Another 1-1/4 miles of a future branch to southeast Corcoran was constructed by Maple Grove. The Council is in the final stages of acquiring ownership of those sewers constructed by the City of Maple Grove. In addition to the above projects, the Council completed the relocation of approximately 7,000 feet of the Elm Creek Interceptor in coordination with MnDOT work along CSAH 81, along with 3,900 feet of the new Dayton-Hassan extension across northern Maple Grove. The relocation resulted from the MnDOT re-design of CSAH 81 in Maple Grove for the future interchange with TH 610 that would have placed major traffic lanes on top of the sewer. The remaining work on the Elm Creek Interceptor consists of two connections serving Corcoran (northeast and south) and part of southeast Rogers. The estimated cost of these remaining connections is $7,000,000. Phase 1 of the Dayton-Hassan Extension was completed in 2008 to within a mile of the border with Corcoran. Because Hassan Township merged with the City of Rogers, the remaining Phase 2 gravity sewer has been renamed the Corcoran/Rogers Connection. That phase is currently beginning design, with construction slated for The shallow gravity sewer portion of the South Corcoran extension was completed along Bass Lake Road in Planning for an associated regional lift station (L80) has been coordinated with Corcoran's trunk sewer improvements and will proceed to design and construction to meet Corcoran s required timing of wastewater service expansion in its southeast district. Purpose and Justification: The interceptor and its branches are needed to serve planned growth in the Elm Creek watershed, while maximizing the use of available capacity in the Council's interceptor system and Metropolitan Treatment Plant. Future growth beyond the capacity of the interceptor system is proposed to be handled by the Northwest Interceptor Improvements and in the long-term, the future proposed Crow River Water Reclamation Plant.

40 Empire Plant Solids Processing: Project 8074 Description: This project provides additional solids processing capacity and process improvements. The recently adopted Facility Plan recommends phased expansion of digestion. Phase 1 of the recommended capital improvements includes the following improvements: 1. The conversion of storage digesters to primary digesters to increase primary digestion capacity by 33%, from 18 dry tons per day (dtpd) to 24 dtpd. Miscellaneous digester system improvements include the replacement of heat exchangers and improvements to the boilers. 2. A new 650 kw combined heat and power system, with biogas treatment and storage, to convert digester gas to electricity.

44 Hopkins System Improvements: Project 8041 Description: This project will replace the existing forcemain and lift station to provide long term, reliable service to the City of Hopkins and St. Louis Park. L-27 was built in 1970 and is need of replacement due to its age, construction and condition. L-27 is a manufactured dry well, built in place wet well station that has had a building enclosure built to protect the station and its equipment. This project will replace the existing lift station with a new lift station near the existing site. The project also includes the construction of a dual forcemain system (two new pipes in some areas and one new pipe plus the rehabilitation of the existing forcemain in the remaining areas) from the new lift station through the cities of Hopkins, St. Louis Park, and Minneapolis. Initial projects included the Wooddale Avenue Forcemain Relocation project which is being done in conjunction with the City of St. Louis Park reconstruction of the intersection of Highway 7 and Wooddale Avenue and the Minneapolis Phase I Improvements. Phase 1 Contract A consists of a new double barrel forcemain between East Calhoun Parkway and Dean Parkway. It has been completed. Minneapolis Contract B consists of a new double barrel forcemain between M132 and Dean Parkway and the construction of a new parallel force main and/or slip-line of the existing forcemain between Lynn Avenue and M132 in St. Louis Park. It is currently under construction. The remainder of the forcemain is under design and will be constructed in 2014 to Purpose and Justification: The purpose of the project is largely rehabilitation to improve the reliability and efficiency of the operation in order to prevent failures associated with an aged conveyance system. It also provides for the long term service needs for the Cities of Hopkins and St. Louis Park.

45 Interceptor 1-MN-310/320 Rehabilitation: Project 8068 Description: These two sewers were originally constructed in Minneapolis in Portions of these sewers are original brick construction. Pipe sizes vary from 3 feet to 10 feet diameter. The pipe length is 12 miles. These sewers will be evaluated to determine their rehabilitation needs. A deep tunnel connection to the Minneapolis East Interceptor will be considered as a means to ensure capacity and reliability of the system and to facilitate rehabilitation of the old sewers. Purpose and Justification: Inspection of these sewers has indicated significant deterioration in some areas. Interim measures have been undertaken to maintain system integrity in areas near the new Twins Stadium and other areas near downtown Minneapolis. A long-term improvement project is necessary to ensure system reliability.

46 Interceptor Rehabilitation Program: Project 8090 Description: The inspection work for the Metropolitan interceptors, lift stations, forcemains, siphons, and meter stations is performed under the operating budget. Depending on type, nature, and schedule requirements, the discovered problem areas are either rehabilitated under this program, repaired under the Interceptor Lining program, done under the ongoing SSIP program, or rehabilitated as part of a major capital program. This is an ongoing program. Each year completed projects are deleted and new projects are added. Only the highest priority projects will be funded within the limits of the authorized budget. Purpose and Justification: The program provides for the follow-up rehabilitation work to correct the problems discovered during routine inspections performed under the operating budget. The project will potentially reduce I/I, rehabilitate deteriorated areas, and improve structural integrity in order to prevent bypassing, structural collapse, or other potential conveyance problems.
