Tatham was retained to provide engineering services for the replacement of two screw pumps and upgrades to the polymer system at the Collingwood Wastewater Treatment Plant. Originally installed in 1982, the pumps are utilized in the activated sludge pumping station to convey return activated sludge to the aeration tanks and waste activated sludge to the sludge thickener.

To accommodate a broad flow range, the replacement pumps were equipped with variable frequency drives. Level switches were also replaced with an ultrasonic level transducer.

Led by our Water & Wastewater team, various Tatham disciplines collaborated in the screw pump replacements. Additional work included the replacement of the existing polymer systems, various process, mechanical, electrical, and structural upgrades, and construction of a new access road and gate.
