cured in place with a heat process. Any given segment is usually completed in one working day. Service line connections are reopened using a robotic cutter and remote cameras. During the process, existing flows are bypassed using pumps. This technology has been proven over the past 20 years, and costs have become competitive with open cut replacement. The City started doing this type of renovation on an annual basis in 2006 and will have an annual project for the foreseeable future to replace our aging sewer infrastructure. This technology also reduces infiltration of groundwater into the system and can be credited toward current and future inflow/ infiltration surcharges which are mandated by the Metropolitan Council. In 2017 approximately 6.2 miles of sanitary pipe are schedule to be lined. The location of this work varies and is spread throughout the City based on system priority. Pipe Replacements/Repairs: Staff evaluates sanitary and water main replacement needs in our pavement replacement areas as well as utility infrastructure needs in County and State project areas. Those replacements are being identified from recent utility inspections and adjustments to the plan will be communicated to the Council at a later date. To date city staff has identified watermain replacements on Gluck Lane, Sandhurst Drive between Albert Street and Hamline Avenue, Sandhurst Drive between Dellwood Street and Fernwood Street, Shryer Avenue between Fernwood Street and Lexington Avenue and Eldridge Avenue east of Fry St. Additionally, the City will be constructing a new watermain just south of County Road C and west of Fairview Avenue to provide a looped watermain system to the businesses on the County Road C Service Rd. Lift Station: The Cleveland Sanitary Sewer Lift Station, located at Cleveland Ave and Brenner Ave, will be replaced in 2017. The lift station was constructed in 1987. The forcemain for this lift station will also be replaced at this time. Staff will begin the design process to replace the Lounge Lift Station located near County Road C2 and Lincoln Drive. This lift station was built in 1989 and needs updates to some hardware in the lift station including guard rail, elbows and valves. Storm sewer system improvements: Staff continues to analyze the existing drainage systems and localized flooding issues and is identifying mitigation projects. Staff is now working on developing a 2017 drainage improvement project to alleviate some of these flooding concerns. Staff has already identified several projects for 2017. Some of the projects include; • Pavement Management Storm Water Upgrades: As part of the pavement management project staff is looking at replacing or adding infrastructure to areas that have had flooding issues. The following areas will have additional storm water improvement completed; o Gluck Lane — Installation of underground storage to reduce some flooding issues. o Burke & Fernwood — Reconstruction of the storm water system in this area. The design will plan for a future underground storage in Keller Mayflower Park. Ultimately these improvements will reduce flooding on Skillman Ave and near St Rose of Lima.
