As part of Environmental Engineering Consulting (EEC) business line of Tetra Tech, Inc., the Surface Water Group (SWG) is a full-service civil engineering, planning, applied sciences, and environmental entity. We are committed to providing growing communities with facilities and systems to improve the quality of life, protect the public health and safety, and restore environmental quality.

The Tetra Tech, Inc. Surface Water Group's origins lie in two small businesses that joined Tetra Tech in the mid 1990's. Simons, Li and Associates, Inc. was a leader in the western US in complex surface water hydraulics and design. FLO Engineering, Inc. specialized in surface water hydrology and hydraulics and was the developer of the widely used FLO-2D model, used today for debris flow modeling on alluvial fans, steady and unsteady state modeling of levees, and for 2D applications. Both firms were well-known for their specialized expertise in water resource related analysis, planning and design services.

Today the Surface Water Group offers expertise in water resource related projects that address issues connected to water quantity, quality, aquatic habitat, and other water-dependent environmental resources. SWG is made up of approximately 70 associates, 5 have earned Ph.D.'s and 22 have earned MS degrees in their areas of specialty.
