Supporting a 35 year long client relationship through this expansion project

The Central Weber Sewer Improvement District provides wastewater treatment for residents of central and eastern portions of Weber County in Northern Utah—approximately 213,000 people. However, the District needed to double the capacity for its wastewater treatment facility to be compliant with current EPA codes and Utah state regulations.

The existing treatment facility was a single-stage trickling filter plant with a rated capacity of 45 million gallons per day (MGD). Based on the needs of the growing community and the new effluent rate and flow-level regulations, the District needed a new parallel activated-sludge treatment plant. 

Our job? To complement the existing 45 MGD facility, provide value engineering, design, and construction management services for a new 30 MGD activated-sludge treatment plant. This expansion to the existing facility included all civil, structural, mechanical, electrical, instrumentation, commissioning, and start-up services. We saved the client $7 million by coming in under budget, maintained normal operations for all facilities during construction, and provided the client with sustainable solutions.

By increasing the facility’s capacity, the District expects to provide ample service to accommodate the area’s growth through 2025.
