BOZEMAN, Mont. -

After hours of discussion, the Bozeman City Commission voted 4-1 on Monday night to approve the Integrated Water Resources Plan. We dug through the document and spoke to Brian Heaston. He is a project engineer with the city of Bozeman and says this plan has been in the works for two years.

"We are proactively planning for the city of Bozemans future water supply needs," said Heaston.

According to Heaston there are approximately 40,000 people in the city of Bozeman. With the current resources, the city is capable of serving around 54,000 people.

Heaston explained to me a big part of the plan includes utilizing current sources -- "Hyalite Creek, Hyalite Reservoir, Sourdough Creek, and Lyman Creek," said Heaston.

The plan also involves identifying new sources, like a potential ground water well field. The plan also calls for conserving water.

"The city of Bozeman is hiring a water conservation specialist," said Heaston.

As Bozeman continues to grow we looked at the projected growth rate according to the plan. The presented plan calls for a 3 percent growth rate annually for the next 30 years. We did the math and at roughly 40,000 people in the city now, 3 percent means an additional 1,200 people per year, for the next 30 years.

Heaston also says right now the amount of indoor use of water in a Bozeman home is 45 gallons per person, per day. Heaston is hoping the plan will show just that, that we can prevent a water shortage from happening.
