Murdoch Sewer Pump Station No. 22

STRUCTURAL RELINING

What was the project?

McRobert Contracting Services were contracted to complete the structural relining of a Type 180 pump station in the Peel region of Mandurah, Western Australia. 10 metres in depth, this pump station required us to reline three areas – two separate wet wells, and an inlet chamber.

Project details

Client: RCR Water

Location: Mandurah, WA

Duration: April – June 2017

Project Background

In 2016, MCS completed a 3D laser scan of the pump station. We determined that all areas had been severely affected by biogenic sulphide corrosion. More than 100% of the concrete cover had deteriorated from the lower sections of the walls of both the wells and the inlet chamber.

What did we do?

Due to the amount of deterioration, MCS was contracted to perform concrete and reinforcement repairs to the walls of the pump station, prior to the installing rigid PVC as per our whaler system patent. See here for how we do this.

We also removed the original benching from the wells and the inlet chamber, before fabricating and installing new benches made from both rigid and flexible PVC. Two penstocks were installed in the inlet chamber, and new gatic lids were fitted in the slab for the wet wells.
