1. BACKGROUND: The Southerly Wastewater Treatment Plant (SWWTP) operates four (4) chlorination and post aeration basins as part of the disinfection treatment process. The current PVC air pipe and ceramic diffuser system was installed in 2006 as part of S69. Due to age and UV exposure, the PVC legs are failing at an accelerated rate. This issue is compounded due to the discontinuation of the air distribution leg by the original equipment manufacturer. This project will replace the post aeration diffusers, replace two centrifugal blowers with hybrid type blowers, rehabilitate three centrifugal bowers, replace the post aeration supply piping, replace and/or repair tank train valves and actuators, sensors and controls for to provide a more automated and energy efficient post aeration system, and other appurtenances to provide a fully post aeration system.
