BDO Outfall Sewer Project

Owner: Central Weber Sewer Improvement District
General Contractor: Whitaker Construction
Project Engineer: Brown And Caldwell

This key $14 million dollar infrastructure project was designed to increase capacity of the existing sewer system and provide a backup pipeline for the sewer outfall line from the City of Ogden to the Center Weber Sewer Plant.
The project consisted of the installation of 12,000 ft. of new 48-inch and 60-inch sewer outfall pipeline, a 72-inch tunneled casing under I-15 and the frontage road, an inverted siphon of the Willard Canal, and new 46 MGD sewer lift station with three 40 horsepower vertical column pumps.
Extensive dewatering was required to ensure no structure settlement. The sewer trunk line required crews to cross two creeks and Willard Canal, newcofferdam construction, and restoration of the existing channels. Numerous sewer bypasses were required to ensure continuous sewer flows during tie-ins to the existing trunk line, including one bypass of more than 32 MGD.
