The Aurora Reservoir Treatment Train at the Binney WPF consists of a conventional treatment process with rapid mix, flocculation, sedimentation, and filtration. The flocculation and sedimentation basins for the Aurora Reservoir Treatment Train were constructed open to the atmosphere. With this exposure, water quality and treatment are subject to wide variations related to weather events. Weather events impact treatment operations with prolonged cold weather events locking up equipment and sun and warm weather contributing to the degraded water quality due to algae growth. Based on the 2012 Treatment System Master Plan, the lack of basin coverage was identified as a deficiency and as a required facility improvement.
The project will include the design of a new super structure over the flocculation/sedimentation basins that matches the existing architecture of the purification facility, conforming to the Parks Recreation and Open Space Master Plan for the Binney WPF Site.
The Work to be performed under this project consists of furnishing all labor, materials equipment, tools, supplies including the installation of a new superstructure to be constructed over the existing flocculation and sedimentation basins. The Work includes the construction of a new superstructure and its various elements and systems, including civil sitework, electrical, mechanical/HVAC, plumbing, limited demolition, equipment lifting devices (davit, bridge, and jib cranes), and access control and security systems.
