Addendum No. 1 authorized the Sanitary District of Decatur to include the new force main construction and construction engineering services to the original pump station Intergovernmental Cooperation Agreement. Apri126,2010—Council Approved Resolution R2010-89 approving the expenditure of an additional $50,000 as part of the Intergovernmental Cooperation Agreement between the City of Decatur and the Sanitary District of Decatur(SDD) for the bid results for the K-Mart Pump Station and Force Main. This addendum brought the total agreement to $537,000. BACKGROUND: Pump Station History The K-mart pump station was built by the developer of the K-Mart Plaza in 1974 to serve the development. The pumps were replaced in 1985 without expanding the capacity of the pump station. Due to recent growth of the area around the K-Mart Plaza and the potential future growth in the area,the existing pump station and force main will not handle the projected flow and the pump station needs to be expanded to serve the developing drainage area. The recommended solution to serve the drainage area for the K-Mart pump station is to replace the existing K-Mart pump station and the force main. The new station and force main will be increased in size to handle the projected flow from the drainage area. Enlarging the pump station capacity requires the existing force main to be replaced with a larger diameter pipe and the discharge location changed to an existing sewer with greater capacity. The existing force main is a 4" diameter pipe installed from the K-mart pump station to a sanitary sewer at the intersection of Airport Road and Baker Woods Lane. The proposed force main is a 6" diameter pipe that would be extended to the intersection of East Cantrell Street and Mount Vernon Place where it will discharge into an existing 12" gravity sewer. CSX Railroad Crossing The existing 4" force main crosses the CSX Railroad perpendicular to the tracks just east of the intersection of Route 121 and 36. The proposed crossing for the new 6" force main will be located next to the existing crossing (with the original crossing abandoned in place) and will be installed by boring and jacking a 75' long 12" steel casing under the railroad right of way from edge to edge with no excavation work on the CSX Railroad property. After the 12" steel casing pipe is installed the 6" force main will be pushed through the casing pipe. The casing pipe will be located at a depth of approximately 7' under the center of the tracks. The Facility Encroachment Agreement from CSX requires the City to accept all liability of the utility crossing except when the damage is proven to be caused by misconduct or negligence by CSX. The City purchased railroad protective liability insurance from CSX. POTENTIAL OBJECTION: There are no known objections to this project.
