Life’s a journey, not a destination.

Sustainable solutions in water infrastructure

From the source to the tap—protecting the quality of our nation’s water is our top priority.

We are stewards of the environment, which informs how we approach projects. Specializing in water treatment and distribution, wastewater systems and stormwater, we are passionate about improving your quality of life and bringing fresh, clean water to all.

Water Treatment and Distribution. Standards for water quality and operational reliability are more complex than ever. We show our clients how technology can enhance day-to-day operations and how energy-efficient processes and distribution systems can save you time and money.

Wastewater Systems. Our extensive experience allows us to design systems that meet regulatory requirements and are also economically sustainable.

Stormwater. Our specialists can help with all aspects of managing stormwater quantity and quality. We make sure our clients are operating in accordance with federal and state regulations and local pollution policies.



An Integrated Capital & Energy Planning (ICE) program helps create a world where capital improvements can pay for themselves, freeing municipalities from always having to impose more burdens on ratepayers or rely on grant funding. Learn More
