Who We Serve

WaterOne is an independent public water utility. We've been proudly serving the Johnson County, Kansas area since 1957. Every day, over 475,000 customers rely on WaterOne to provide fresh, clean water on demand. It's a responsibility we deliver on.

Our passion is water because water touches everything we care about: family, health, safety, and community. We serve our community by bringing award-winning water to their homes, businesses, and public places.

Our History

We're a public utility by customers, for customers. WaterOne was born from our customers' desire for great water, reliably.

In 1957, unsatisfied with the value and service from their water provider, residents in the Mission area came together to buy out the Kansas City Suburban Water Company. They reincorporated as public water provider Water District Number 1 of Johnson County. Today, we go by WaterOne and we've grown to service most of Johnson County.

The Little Water Company That Could

When we began, we were supplying up to 5 million gallons per day (mgd). Today, we have the capacity to make 200 mgd to meet our customers' needs.

That's a lot of water.

We're able to grow to meet the demand because we follow our Master Plan, a comprehensive road map for expansion and sustainability. We make continual investments in infrastructure at the right time so a plentiful supply of delicious water is available for our customers.

And we're thinking about the future, carefully managing the utility so that our services are here for the next generation. At WaterOne, we believe in the meaningful work of producing clean water because we're making it for you.
