Underwood Water Treatment Plant
Billings, Montana

 

In 1915 the City of Billings purchased its waterworks from Montana Water Company at a cost of $315,000. The original waterworks plant was built in 1886-87, and at that time, the City had a population of approximately one thousand. Since then the City of Billings Water Treatment Facility (aka Gerald D. Underwood Water Treatment Plant) has continued to expand in an ongoing effort to keep up with the growth of Billings. The source of supply for the City's waterworks is the Yellowstone River. The nominal capacity of the water treatment plant is about 50 million gallons per day (MGD). Daily average usage is approximately 24 MGD. However at peak times during the summer months the plant will process at capacity, 50 MGD. Water is pumped from the plant to eleven different zones within the City, and a 600-foot elevation differential exists between the highest and lowest portions of the City's water service area. The plant currently services approximately 115,000 people.


Current Expansion 

In 2005 the City of Billings contracted with COP Construction LLC to renovate and expand the Underwood facility. This was a very technically challenging project in many respects, especially in light of the fact that this was a renovation/expansion around an ongoing operation. The completed project was estimated at $17 million and took about two years to complete. When completed, the treatment plant's capacity increased about 20% or to a capacity of 60 MGD. This should serve the City's population well into the future.
