Welcome to Roseville

Nestled among rolling hills and surrounded by 360-degree panoramic views of the Sierra Nevada and Sutter-Butte mountains, Roseville provides a natural setting that rejuvenates and energizes its communities’—and our water and environmental engineers.

In our backyard, we designed and now operate Lincoln’s award-winning wastewater treatment plant. In nearby Merced, we upgraded its wastewater facilities to protect its natural resources for future generations. In New Orleans, we’re designing pumps that reduce risk from a 100-year storm event to help the community recover from Hurricane Katrina.

Energized by the work we do and the beauty around us, we focus our passion to help Roseville's communities preserve their natural heritage, rejuvenate, and thrive.
