About Us

We provide more than just water — we provide water service. When you call one of our Customer Centers, you talk directly to a local person who knows your community and your water system. And while our operations and customer services are provided locally, our engineering, water quality, and billing services are centralized at our headquarters to provide the best value.

In everything we do, we stay focused on serving the customer. That means investing wisely in infrastructure to ensure a reliable supply, both now and in the future. It means maintaining a top-notch team of water quality experts to ensure that we meet increasingly strict water quality standards. It means ensuring that every one of our customer service representatives has the tools and ability to meet customers’ needs the first time they call. And it means checking in with our customers periodically to see how we are doing.
