Who We Are
Big Spring Water has been bottling fresh, spring water straight from the Big Snowy Mountains since 1966.

A Montana Legacy

No stranger to the beverage industry, we are proudly owned by Lehrkinds who have been serving Montana with everything from beer to sarsaparilla to Coca-Cola since 1885. Big Spring Water is bottled by Blue Water Works LLC in Lewistown, MT.

Our Spring Water
Our water is gathered from a mineral-infused spring 1200 feet underground that produces 90 million gallons a day. It travels up through limestone layers to a protected pipeline where it is transported into the Lewistown facility.

Mineral Content
Unlike many other popular bottling plants, our water is not a product of reverse osmosis or aero treatment, but contains the naturally occurring minerals directly from the spring — giving our water its fresh, mountain taste.

Big Spring Water undergoes extensive FDA-approved lab testing to ensure the quality remains unchanged. As required, ozone — an oxygen gas that prevents bacteria and viruses from forming — is added at the plant to ensure that our water is preserved for a long shelf life. pH verification tests are carried out every two hours at our plant and bacteria testing takes place weekly. Additionally, our lab in Billings conducts annual tests on all the minerals that are in the water to double check for any pesticides, herbicides, or other contaminants.

Our Commitment to the Environment
In an effort to reduce the amount of plastic waste generated from bottled water, Big Spring Water has reduced the number of smaller, individual serving bottles it packages and instead encourages the use of reusable 3 and 5-gallon jugs. Bottles are shipped in reusable crates. To find recycling centers near you, or to find out more about the ongoing recycling efforts in Montana, visit the resources below.
