Box 8 <br />Silt CO 81652 <br /> <br />Subject: Grass Valley Canal Siphon Replacement Cost, Silt Project, Colorado <br /> <br />~ar Mr. Dodero: <br /> <br />As requested, I am providing a rough cost-estimate for the replacement of the upstream <br />siphon on the Farmers Irrigation Company's Grass Valley Canal. Installed over 50 years <br />ago, the existing pipe and supports along with new inlet and outlet structures require <br />replacement. Initial cost estimates for these improvements are as follows: <br /> <br />570 feet - 48" poly-coated steel pipe <br />Concrete Pipe Supports <br />Concrete Inlet and Outlet Structures <br />Ring Girder Supports <br />Installation <br />Contingencies - 30% <br />Total <br /> <br />$106,000 <br />$ 30,000 <br />$ 50,000 <br />$ 23,000 <br />$ 60,000 SWCD EST, $210,000 <br />$ 81.000 <br />$350,000 $500,000 <br /> <br />A more refined estimate can be obtained after further detailed design work is completed. <br />Please give me a call if you have questions or need further information. <br /> <br /> <br />an <br />Water Management Group Chief <br /> <br />
