This project consisted of a new 17 million-gallon-per-day (MGD) wastewater pumping station with a reinforced concrete wet well/dry well with three submersible dry pumps and building. The project also included a grinder structure, diversion structure, and 11 million-gallon prestressed concrete, wire-wound equalization tank. Modifications were made to the existing building for a 24 MGD equalization pump station. The project also included electrical upgrades and miscellaneous site improvements.
A temporary system bypassing the existing influent flow was necessary to bring the new diversion structure, grinder structure, and pump station on line. The temporary system was capable of bypassing 9 MGD.
Civil work included rock excavation, rock anchors, and temporary shoring. Architectural items included light gauge tresses, split-face masonry, waterproofing, and a standing seam roof system.
The confined nature of the work site and proximity to existing facilities required detailed planning and logistical forethought by the project team to maintain the proper construction sequencing.
