Finham currently consists of two separate inlet works, at the Sherbourne and the Sowe, each providing screening and degritting treatment before combining and passing forward to two separate primary sedimentation streams.
Other works to be completed include additional storm treatment capacity (on the Sowe inlet), refurbishment of Sowe inlet works screening and degritting plant, installation of new high voltage system to works.
The project consists of the construction of new headwork facilities, including new course screens, new degritting equipment and new fine screens; new waste activated sludge thickening facility; new aeration tanks and blower building and the modification of the existing aeration tanks; five new secondary clarifiers; new filter influent pump station; new effluent filters; new ultraviolet disinfection facilities and various other improvements.
Project Description: This project is comprised of two sub-projects: YZ01 Primary Sludge Screening & Degritting Wet Well Control involves installation of new controls for the primary sludge screens and the Degritting and Grinding Facility wet well at the Blue Plains AWTP; and YZ02 Digestion Facility Demolition and Site
Project Description: The objective of this project is to design and construct the improvements needed to rehabilitate and upgrade the Primary Sludge Screening & Degritting Building (PSSDB) and the Gravity Thickeners (GT) at the Blue Plains Advanced Wastewater Treatment Plant (AWTP).
