Shea Parsons Joint Venture (SPJV) is working on finishing up its installation of the Receiving Lift Station (RLS) pump discharge pipes that connect the shaft to the new headworks facility. These pipes will deliver wastewater from the RLS pumps to the headworks facility where large sediment and grit are screened out and removed.
SPJV is carrying out architectural work to install stairs and handrails around the headworks facility and large equipment such as the bio-trickling filters (BTF), one component of the odor control system. Bio-trickling filters treat foul air that comes from the gravity pipeline tunnel and headworks facility. The BTF is the first form of treatment using biological processes to treat foul air compounds typically generated during wastewater conveyance and pre-treatment. The air flow passes from the BTFs to the Granular Activated Carbon (GAC) vessels for final treatment. The treated air is then permitted to be exhausted into the atmosphere.
