Water & Wastewater


Reliable drinking water and wastewater treatment are vital to both public and private users.

Whether expanding or improving facilities, or constructing new ones, we provide cost certainty and minimal disruptions to operations. Our value engineering and constructability recommendations maximize construction dollars for rate-payers. We find ways to expedite schedules to deliver capacity sooner. Also, specialty treatment equipment can cost millions and require long lead times and special design considerations. Sundt offers guidance on these critical decisions and ensures that long-term reliability and life-cycle costs are part of the equation.

Since 1948, Sundt has been a trusted builder for water and wastewater treatment, with more than 60 plants in the last 15 years alone. 

Our first wastewater treatment plant incorporated non-potable irrigation reuse. Today, we remain at the forefront of treatment technologies, delivering advanced water treatment facilities for indirect potable reuse and zero liquid discharge (ZLD). Our collaborative approach to project delivery is based on meeting client needs, including options for CMAR, Design-Build, and CM/GC delivery. We have experience with several advanced technologies, including:

  • filtration
  • membrane treatment (including reverse osmosis)
  • desalination
  • advanced oxidation
  • brine recovery
  • zero liquid discharge (ZLD)
