Mancos Water Conservancy District Agenda Item 20a. November 25-26,2002 (Updated December 2,2002) Mancos Water Conservancy District The MWCD was organized January 6, 1941 pursuant to the Water Conservancy Act of 1937, 37-45-101 et sea C.R.S. The District has the power to acquire and sell water rights, construct and operate facilities, exercise eminent domain, levy taxes, and contract with other agencies, including the CWCB. The MWCD established a water activity enterprise fund in 1993, in accordance with the provisions of TABOR. Project Description Three alternatives were analyzed in the feasibility study: 1. The no-action alternative. 2. Rehabilitate the inlet canal ($4.1 million.) 3. Rehabilitate the inlet and outlet canals ($6.62 million.) Alternative No. 1: No Action. This alternative is unacceptable because it will result in escalating maintenance and repair costs, and increases the possibility of a serious failure that would make it impossible to deliver water to customers (water users) during critical periods. District facilities are over 50 years old and the MWCD has had to make emergency repairs to the inlet/outlet canals on several occasions during the past 10 years. It is a matter of time before a failure renders the system inoperable for an extended period. Alternative No. 2: Rehabilitate the inlet canal ($4.1million.) This alternative would address the most critical repairs (inlet canal), and delay rehabilitation of the outlet canal. This alternative was not selected since a sudden failure of the outlet canal, although less likely, would still shut down the system. Alternative No. 3: Rehabilitate the inlet and outlet canals ($6.62 million.) This alternative was selected since it will allow the District to systematically schedule and complete rehabilitation of the entire canal system. Selected Alternative No. 3 The MWCD will use the loan from the CWCB to rehabilitate the inlet and outlet canals to the Jackson Gulch Reservoir. The MWCD will also replace its shop and headquarters buildings, and consolidate 3 of its 5 existing loans. The cost estimate is as follows: Proiect Item Estimated Cost (Millions) Inlet Canal-Replace Concrete Bench flumes (all of Sections 1 and 3) $3.21 Inlet Canal-Install Buried Geomembrane liner (all of Sections 2 and 4) $0.53 Inlet Canal-Replace Concrete Drop Chute (all of Sections 5) $0.36 Outlet Canal-Install Buried Geomembrane liner (all of Sections 1 and 3) $0.81 Outlet Canal- Replace Concrete Bench flumes (all of Section 2) $0.73 Outlet Canal-Replace Concrete Drop Chute (all of Section 4) $0.36 Shop and Headquarters buildings-Replace $0.20 Loan Consolidation-SWCD (2 loans), and Mancos Valley Bank $0.18 Total $6.62 Million 2
