Mt Crosby East Bank WTP filter upgrade

Seqwater operates more than 30 water treatment plants across South East Queensland.

The Mount Crosby East Bank Water Treatment Plant (WTP) turns raw water into safe, drinkable water for the Brisbane and Ipswich area.

East Bank and West Bank water treatment plants, both located at Mount Crosby, can produce up to 800 megalitres of drinking water each day.

Filter upgrade project

To improve the long-term capacity and reliability of this important infrastructure, Seqwater will be making a number of repairs and upgrades at the plant.

This work will be completed in stages, starting with the oldest section first. The first rapid sand filters at the Mt Crosby East Bank WTP were built in 1945.

In total, there are 20 filters at the plant which require refurbishment. The filters are an essential part in the water treatment process which assists with clarifying the water prior to disinfection.

    The history of the East Bank filters

    It was the Queensland Premier of the time, Mr E M Hanlon, who commissioned the oldest section of the East Bank Water Treatment Plant on 13 May 1948.

    This section of the plant will be the first to undergo an upgrade when the Mount Crosby Filter Refurbishment project commences.

    It was the Queensland Premier of the time, Mr E M Hanlon, who commissioned the oldest section of the East Bank Water Treatment Plant on 13 May 1948.

    This section of the plant will be the first to undergo an upgrade when the Mount Crosby Filter Refurbishment project commences. The first six filters will be taken offline in March 2020.

    Senior Project Manager Bart Vervetjes said some of the filter design was developed during World War II at a time when demands on the water supply due to population growth and the war effort resulted in the first three of the Stage 1 filters being brought into operation 23 months after construction started in February 1944. The remaining three following in March 1946 at a total cost of £250,000.

    Mr Vervetjes said these filters and their similar three stages built over the next 22 years had served the public well and had endeared themselves to generations of staff who had operated them.

    “The refurbishment works will incorporate improvements in filter design and control, to ensure that these assets continue to assist with the provision of safe and reliable drinking water well into the 21st century,” he said.

    “The program of works includes the staged refurbishment and upgrade of the 20 filters and related infrastructure at the water treatment plant.

    “Work will be completed in five stages, starting with the oldest section which was commissioned by Premier Hanlon.”

    The filter refurbishment will be completed in stages to minimise the plant maximum capacity aiming to reduce the risk of disruption to Brisbane’s water supply.

    The two Mount Crosby Water Treatment Plans are critical assets for the greater Brisbane water supply. Between them (East Bank and West Bank WTPs) the water treated comprises of approximately 60 per cent of Seqwater’s total water allocations.

    The Mt Crosby East Bank filter refurbishment contract was recently signed by CEO Neil Brennan and BMD Group Executive Directors Craig Mortensen and Paul Fogarty.

    The contract is the highest ever value construction contract Seqwater has entered into.

    The $27 million contract covers a program of works expected to take three years to complete.
