The Water Treatment Plant provides the citizens of Bozeman with a safe and dependable drinking water supply. The City of Bozeman has been supplying water to city residents since 1889.

The city's source water comes from Lyman Creek in the Bridger Mountains, and from Sourdough and Hyalite Creeks in the Gallatin Mountains. In the Hyalite creek drainage the city has 5400 acre feet of water storage in the Middle Creek Reservoir (also known as Hyalite Reservoir), this comprises about half of the stored water from that source.

Water from the Sourdough and Hyalite drainages is treated at the Sourdough Water Treatment Plant. The Sourdough Water Treatment Plant was constructed as a ten million gallon a day plant in 1984. An additional five million gallons of capacity was added in 1993. At the Sourdough plant, raw water is filtered through an anthracite and sand filter media. The water is then chlorinated, fluoridated, and chemically adjusted to make it less corrosive. The Sourdough Water Treatment Plant delivers about 80% of the water requirement for the City; it is located at the mouth of Sourdough Canyon, south of Bozeman.

The water from the Lyman Creek source is groundwater. It is chlorinated and fluoridated, then introduced to the distribution system. Production from the Lyman spring varies through the year, peaking in early summer at 3.7 million gallons a day.

There are three finished water storage tanks providing, when full, eleven million gallons of storage.

For quality assurance, Water Treatment Plant division employees conduct a rigorous water quality sampling and testing schedule at the plants and in the distribution system. Water Plant employees also are responsible for the care and maintenance of the three finished water storage tanks.
