The seven participating entities are: City of Montrose; City of Delta;
Town of 01athe; Tri-County Water Conservancy District (Tri-County);
Chipeta Water Company; Menoken Water Company and Uncompahgre Valley Water
Users Association (UVWUA). Under the present operating scheme, Project 7
treats and delivers water to all the participating agencies except UVWUA.
These agencies then distribute the treated water to their customers. The
UVWUA, as described previously in this section, is a purveyor of
untreated rather than treated water.

Project 7 went into operation in 1980 after aCQUlrlng and enlarging
the Montrose Water Filter Plant, and constructing a 25-mi1e transmission
pipeline (18 to 30 inches in diameter) along Highway 50 from Montrose to
Delta. The water plant presently has a 26 mgd capacity, and in 1986
operated at an average rate of 5.1 mgd, treating a total of 5690 af of
water for the participating entities (See Table 8.2).

Project 7 does not own water rights nor does it have taxing
authority, but is reimbursed monthly by the participants for the Quantity
of water treated and delivered to them. At present, raw water is
purchased by each entity from Tri -County, who in turn purchases water
from the UVWUA under an interim contract until the Dallas Creek water
supplies are avi1able. In addition, the City of Montrose obtains part of
its raw water supply from the Cimarron Ditch and Reservoir Company and
delivers it to Project 7 for treatment. The UVWUA water is fed by
gravity from the Gunnison Tunnel and South Canal to Fairview Reservoir,
which is a 500-af water storage reservoir owned and operated by Project
7. The Cimarron Ditch water is stored in Montrose Reservoir (previously
called Cerro Reservoir) and then conveyed by pipeline to Fairview
Reservoir. Both the 800 af Montrose Reservoir and the pipe1 ine from
Montrose to Fairview Reservoir are owned by the City of Montrose. Other
water supply facilities which were previously operated by the
participants are no longer in use but are kept operational for backup
purposes.
