The East Bank Flood Resilience Program is investigating improvements to the historical Mount Crosby East Bank Pump Station to reduce flood risks to the essential bulk water infrastructure.
The Mount Crosby East Bank and West Bank Water Treatment Plants are a critical part of the SEQ Water Grid and supply about 50 per cent of South East Queensland’s drinking water, including the cities of Brisbane, Ipswich and Logan. Following the severe flood events in 2011 and 2013, Seqwater identified improvements across the SEQ Water Grid to improve resilience during all weather conditions.
In 2016, Seqwater began a detailed assessment of the East Bank Raw Water Pump Station site and its ability to withstand and recover from a flood. The Brisbane River Catchment Flood Study showed the probability of floodwater inundating the East Bank Pump Station site was greater than previously thought.
Seqwater’s East Bank Flood Resilience Program involves a number of improvements over five years, to reduce flood risks to critical bulk water infrastructure, while rejuvenating the surrounding historical precinct. Due to the interconnected nature of the individual projects within the program, a master plan has been developed encompassing the East Bank Raw Water Pump Station and the construction of a new public road bridge to improve access to the area.
This proposal is specifically investigating renewal works for the East Bank Raw Water Pump Station, which supplies the East Bank Water Treatment Plant and associated critical electrical infrastructure.
BUILDING QUEENSLAND ROLE
Building Queensland is assisting Seqwater to develop the options analysis. Building Queensland’s assistance is focused on helping Seqwater align their analysis with the Business Case Development Framework and applying the appropriate assurance requirements.
Building Queensland is helping to identify and resolve critical issues that may negatively impact the time, cost and quality of the potential project, and develop a robust implementation plan.
