Water & Wastewater

Water and wastewater companies face significant challenges as they seek engineering solutions to collect, drain, store, transport, treat, discharge and distribute water safely and effectively. These organizations rely upon a multitude of physical analyses — including computational fluid dynamics (CFD), hydraulics and mass transfer predictions — to model and verify the behavior and flows of water under a wide range of conditions.
