This project was awarded at the July 5 City Council meeting and consists of rehabilitating various sanitary sewers and appurtenances located throughout the City. It includes a total of approximately 800 lineal feet of new sanitary sewer installed by Horizontal Directional Drilling in the south 500 block of Lynn Street neighborhood and “upsizing” approximately 280 lineal feet of existing sanitary sewer from 6-inch diameter to 8-inch diameter sewer by Pipe Bursting in the south 500 block of Elm Street. Adjusting manhole elevations in the west 700 block of Washington Street to improve street drainage in that block is also part of the project as well as future unknown but, expected repairs to the City’s sanitary sewer system for a one-year period following award of the contract. Directional drilling and pipe bursting are used in sewer construction to reduce the amount of surface disruption. Cross Construction is the contractor for the project at a total a cost of $345,753.
Work was completed on the pipe bursting in Elm Street. Directional drilling was started in the alley between Lynn Street and Elm Street north of Green Street. This will be followed by directional drilling and installing new sewers in the south 500 block of Lynn Street. This project is behind schedule, but should be completed by Wednesday, September 26, 2012.
