The Project 7 Water Authority is a unique cooperative effort among seven water entities to provide high quality potable water to the municipalities and rural areas of the Uncompahgre River Valley.
The seven entities that represent the Project 7 Water Authority are:

• The City of Montrose
• The City of Delta
• The Town of Olathe
• The Tri-County Water Conservancy District
• The Chipeta Water District
• The Menoken Water District
• The Uncompahgre Valley Water Users Association

The governing body of the Authority is a six member Board of Directors in which all legislative power of the Authority is vested. Blue are voting members (and also will take you to websites of these entities.) 
The Authority was established on September 29, 1977, pursuant to the provisions of Colorado Revised Statutes (CRS) 1973, 29-1-203.2, as a separate governmental entity to effect the treatment of raw water and transmission of finished water.

During the summer of 1973, the City of Montrose experienced water shortages as a result of insufficient treatment capacity during peak demand periods. The Tri-County Water Conservancy District was almost totally dependent on Montrose for their water at that time.

The City of Delta and Town of Olathe were also experiencing some of these same problems. The Menoken Water District and the Chipeta Water District were also faced with outdated treatment facilities and at times a problematic raw water supply.

These six entities and their desire to resolve their common problems initiated the formation of the Project 7 Water Authority.

The Uncompahgre Valley Water Users Association joined as the seventh entity due to their involvement in providing the raw water flow to the Project 7 Water Treatment Plant.

Funding to construct the project was obtained from the then Farmers Home Administration, known today as the Rural Development Administration. The grant/loan combination in the amount of $14 million was used to purchase an existing water treatment plant and raw water reservoir from the City of Montrose, and construct the necessary pipelines.

That treatment plant was then retrofitted and expanded to its current capacity of 27.6 million gallon per day (MGD). Additionally, Project 7 constructed approximately 30 miles of transmission line, pressure regulating stations and master metering stations to deliver water to the participating entities.

The system went on line in July 1980.

There have been significant improvements made to the system since 1980; one of the largest was the construction of 2 - 5 million gallon finished water reservoirs (tanks) built in 1995.
