Annacis Island Wastewater Treatment Plant SCT Blower Replacement

The Annacis Island Wastewater Treatment Plant Blower Installation project includ­ed the removal of two existing solids contact tank blowers and associated items and the installation of three new 700hp blowers with three pad mounted trans­forms and associated items.

To complete the upgrade on the MCC/Switchgear to accommodate the three new blowers, a new soft starter for Blower 1 and a temporary Diesel Gen­erator were required to be on standby for the emergency usage of Blower 1, which was an existing 800hp Blower.

Along with the blower upgrades, there was a CDAC upgrade that included new instrumentation, controls, a control panel, and termination panels. All work was coordinated around an operating facility to ensure no plant interrup­tions occurred.

NAC self performed all civil, mechanical and electrical works for this project.
