BIG GULCH TRUNK SEWER DIVERSION Project Use: Sewer Diversion Structure the structure at all times, the screens are completely removable to allow for maintenance and cleaning. Granite Precasting was able to design, fabricate and deliver this structure in five weeks with the help of an advanced 3-D modeling program. By using precast SECOND PLACE UNDERGROUND Project Location: Mukilteo, Washington The Big Gulch Trunk Sewer diversion structure diverts excess water from the existing culvert in order to prevent flooding and erosion while protecting the fish habitat. When the existing culvert cannot keep up with the flow of the stream, the diversion structure serves as an emergency overflow. The culvert allows water to flow past the fish screens, over the height-adjustable baffle, into the structure and into the city’s storm system after passing through an inspection and sediment vault. The aluminum fish screens prevent fish from entering the storm system, and to ensure the proper function of concrete, the deadline for the fish and wildlife regulations was easily met. For ease of construction and to keep shipping weight down, the structure was built in three sections. Then to ensure quality, the structure was preassembled to ensure proper fit and disassembled prior to shipping. The use of precast over cast-in-place kept the stream flow interruption to an absolute minimum and provided a low-impact, quality solution for the city of Mukilteo.
