Water Treatment


Did you know Yellowstone maintains and operates 23 water treatment plants? They range from large frontcountry operations in areas like Mammoth Hot Springs, Canyon, and Old Faithful to rustic, hand-operated well pumps in remote backcountry outposts. On a normal summer day in Mammoth Hot Springs, certified utility operators like Rafal work to produce and distribute (via gravity) about 350,000 gallons of clean tap water for the 352 homes, office buildings, and lodging in the area.

"I'm honored to be a member of the team that provides our community with such a vital need. The job requires not just the ability to perform calculations and solve problems, but also integrity and a strong sense of duty. You have to show up every day with the public in mind." - Utilities Operator Rafal Kos
