and a day tank. The water blending station will be located at the Town's existing water tank site. Current projections show that the Town only needs the volume supplied by an eight-inch line. The capacity of an eight inch line equates to 416 gpm compared to the existing total maximum day flow of the Town's wells being 315 gpm. The facilities in this alternative would be designed, constructed and owned by the Town who would also operate them. In order to accommodate future growth that may exceed the projected 4%, the project will be bid with both 8-inch and 12-inch pipe sizes. Constructing a 12- inch line would increase the line capacity to 833 gpm and also allow the Town to sell wholesale water to Pioneer Community Developments and provide for purchase of water from Pioneer, should the Town's system ever be inoperable for any reason. Alternative 2 This alternative involves the purchase of water from an unnamed landowner located in the Lost Creek water shed. Because the seller of water has not been identified for this alternative, an estimate was made based on a farm located in the middle of the Lost Creek water shed and along the alignment of the proposed pipeline route to the Town's existing Roggen wells that are currently not being used. It is estimated that approximately 9.2 miles of 8-inch piping would be required to deliver water to the existing Town water tanks. The cost analysis presented includes two lift stations. This is required because the elevation lift is higher than what can be accomplished with one lift station. To provide backup reliability of the system, the project design would include the construction of a parallel 8-inch pipe for approximately 15,800 feet. This pipe would ultimately be used for sending water from the Town's Roggen wells to a new water tank on the NE side of Town. The Roggen water alternative is further explained below in Alternative 2A. The cost for this additional piping is not included in the attached cost matrix for Alternative 2. The total cost for this parallel section would be in the range of $534,000 if it were constructed separately from the Alternative 2 project. Constructing this as a parallel line with Alternative 2 would reduce the pipeline costs to $267,000. Alternative 2A This alternative is a phased expansion of Alternative 2 to construct approximately 10.2 miles of new water line to transport the 247 acre feet of Roggen water to the proposed Keenesburg water tank site. Using the water from the two Roggen wells with a decreed capacity of 247 acre- feet will more than double the current decreed capacity of the Town's wells, Feasibility Study -Keenesburg, CO 1/23/2009 7
