6.2 Front Street Sanitary Sewer CITY OF SALINA REQUEST FOR CITY COMMISSION ACTION DATE TIME 12/14/2009 4:00 P.M. AGENDA SECTION NO: 6 ORIGINATING DEPARTMENT: APPROVED FOR AGENDA: UTILITIES DEPARTMENT ITEM NO. Page 1 2 BY: Martha Tasker BY: ITEM: Award of contract for the Front Street Sanitary Sewer Reconstruction and Manhole Replacement, Project No. 09-2769. BACKGROUND: City staff identified a bottleneck in the existing 24-inch gravity sanitary sewer line directly up stream of Wastewater Pump Station No.1 (located near Central Garage). The existing 24-inch line reduces down to a 12-inch line for a distance of approximately 1,650 feet. The existing 12-inch line is too small to handle wet weather flows and occasionally surcharges / backs wastewater in the existing gravity sewer system. The Grand Avenue Master Utility Plan recommended replacing this existing 12-inch line with a 24-inch line to provide capacity for future growth in an area bound on the north by Euclid Avenue, on the south by North Street, on the east by the Dry Creek Channel and on the west by the Flood Control Levee. In addition, up-sizing this line will provide capacity for future growth in the Diamond Drive area. Three existing manholes have deteriorated to a point where repair IS not possible and require replacement. These manholes are located at the following locations: . Ash Street and Des Moines Avenue . Franklin Street and Broadway Boulevard . Ohio Street and Republic Avenue Bids were received on December 8, 2009 as follows: Bidder Nowak Construction Co., Inc. 200 S.

Pipe reaming will be utilized to up-size the existing 12-inch line to a 24-inch line. Pipe reaming is a process where the existing 12-inch line and soil are ground up, pulverized and removed to allow the new 24-inch line to be pulled in place.
