OUR WATER WORKS.

We stand by our projects with pride and a commitment to seeing them produce quality effluent for generations.

we’ve provided our technologies to over 8,000 water and wastewater projects around the world.

From mechanical plants to lagoon-based wastewater treatment, whether in North America, South America, Europe or Asia, our projects are on the cutting edge of treatment for nutrients and energy efficiency.

The following case studies illuminate some of the more interesting, exciting, and representative work we’ve had the privilege to work on.
