CASE WATER/SEWER EXTENSION TO THE POLICE/MUNICIPAL BUILDING By: Steve Jankowski, City Engineer Background: With the impending construction of the new Police building, and the relatively close proximity of municipal water and sewer service to the municipal building complex, it would be prudent to consider the cost of extending these services to the municipal campus. The Building Inspector estimates that it may cost up to $15,000 to install a septic system for the Police Department and connect water to :the facility from the municipal building. In addition, the lack of sprinkler capabilities would have cost impacts on the design of the building (i.e. more access points). The purpose of this case is to identify the costs associated with the extension of municipal services to the municipal complex. I have evaluated two options for the extension of sewer and water to the municipal complex. First, utilities could be Jextended from the proposed Brandseth subdivision which would extend both utilities to the CiW's eastern property line. The second alternative would be to extend the utilities from the eastern portion of the Haubrich Addition. Below is a summary of the estimated total project costs for the extension of sewer and water utilities from each of these sources. Utility_ Ex!ension Sewer W0ter Total From Brandseth Addition $41,500 $50,200 $ 91,700 From Haubrich Addition $57,600 $63,200 $120,800 The results of this comparison show a significant cost advantage for extending the utilities from the Brandseth subdivision. Although, the physical distance to the Haubrich Addition is slightly closer, the following factors are responsible for the lower cost alternative being the Brandseth expansion. 1) The Haubrich Addition requires the C.S.A.H. #5 to be jacked for both the sewer and the water. 2) The per foot construction costs along 151st Avenue and C.S.A.H. #5 will be higher than through Open field. 3) To provide gravity services from the Haubrich Addition would require 200 feet of existing sewer to be re-laid at a flatter grade. .De. scription of Preferred Alternatives The sewer and water utilities would be extended westward along the extension of proposed 152nd Avenue in the Brandseth Addition. The watermain would be brought along the south side of the municipal building. A pair of four-inch services would be stubbed out for the new Police building and for connection to the municipal building well discharge. A fn'e hydrant would be placed at the end of the line for fire protection and flushing. Sanitary sewer would be extended into the parking lot with a manhole terminating in front of the east overhead doors of the fire station. It would be necessary to redirect the existing sanitary sewer discharge to this point. This could be accomplished by cutting and re-laying piping under the Fire Department garage floor. A budget of $5,000 was anticipated for this work. Restoration costs associated with parking lot and turf replacement, as well as 30 percent project overhead are included in the above costs.
