11. Dolores Water Conservancy District - Dove Creek Secondary Water
Supply System

Authorization: Construction Fund
Water Source: San Juan/Dolores
Terms of Loan: $883,[e-mail]% for lO-years

County: Dolores
Project Yield: 300 acre-feet
Project Type: Dual Water System

.

Residents of the Town of Dove Creek currently use existing treated water supply for
outside irrigation. DWCD has been working with the Town, and the Town's Secondary
Water Supply Committee, to provide a more cost effective raw water supply for outside
irrigation. Currently the cost of treated outside irrigation water for Town residents is
$2.40 to $3.00 per thousand gallons. Through a Franchise Agreement, DWCD will make
available 300 acre-feet of its municipal and industrial (M & I) water to meet the needs of
the Town, and will construct and operate a secondary water delivery system. The
system will include a new pumping plant to deliver up to 2 cfs, a 5 to 10 acre-foot
terminal storage reservoir, 32,000 feet of delivery pipeline (10"-8660 feet, 8"-7480 feet,
6"-16,480 feet) and 307 individual taps with water meters (314 to I-inch capacity) for
supplying up to 10 gallons per minute per household. With the new systems outside
irrigation can be provided at about $1.26 per 1000 gallons, including annual operation
and maintenance. The project will be paid for by tap fees, and a total of 307 taps are
required to generate enough revenue to fully repay the project cost. The project is being
constructed in-kind by the Dolores Water Conservancy District and is currently under
construction. The project is approximately 85% complete and is anticipated to be
finished by the October of 2007.

The Little Thompson Water District and the Central Weld County Water Districts have a
50/50 partnership to construct, own and operate a new reservoir (Dry Creek Reservoir).
The proposed project, located approximately 2 miles southeast of Carter Lake would
include construction of a 5,200 acre-foot reservoir, including a 40-foot high earthen dam
with an emergency spillway and outlet works. Construction will also include
converting an existing 20-inch treated line to a raw water delivery line that will connect
from the Filter Plant at Carter Lake to the new reservoir and the construction of a 5000
GPM pump station. The project scope was recently changed to increase the reservoir '
