Mechanical and electrical focus
Aging components, the availability of new technology and an increase in flows due to development meant an upgrade was needed.
The station discharges through a 400mm diameter forcemain into a manhole approximately 6200m south of the station.
The mechanical upgrade included the supply and installation of:
- An electromagnetic flowmeter in the existing forcemain, including piping, precast manhole, and drainage piping
- A third 130 HP submersible pump together with a discharge unit and connection to the existing discharge header
- A sluice gate valve on the existing partition wall inside the wet well
The project also included the construction of four cover plates on the existing openings, with open/close mechanism to allow for isolation of each of the two wet well sections.
The electrical upgrades included the supply and installation of a new solid state starter unit within the existing empty motor control centre (MCC) section.
