WSSC 100th Anniversary

At WSSC, we’ve always got an eye toward the future, seeking out the best approaches to service and delivery. It’s all part of our journey to be THE world-class water utility, where excellent products and services are always on tap.

But in 2018, we’ll be taking a look back. That’s because in 2018 WSSC celebrates 100 years of service; 100 years of providing clean water to our customers with ZERO water quality violations. 

We’re proudly celebrating all we’ve achieved and how far we’ve come over these past 10 decades, and we want you to be part of our Centennial celebration. After all, we wouldn’t be here if it weren’t for you. 

Our centennial theme is A Century of Serving Our Community, and we’re hosting several exciting events that highlight our past, present and future, as well as the value of water and our contributions to the water industry. We invite you to join us, and share in our pride of 100 years of service. 

Stay tuned for details as 2018 draws near. For now, check out the calendar of events planned for the communities we proudly serve. Event times will be announced later. See sign up form below.
