Nabiac Water Treatment Plant Upgrade

A planned upgrade to the Nabiac Water Treatment Plant will increase the plant’s treatment capacity from 12 megalitres per day to 18 megalitres per day and provide greater drought security for the Manning Water Supply System.

In order to meet the requirements of the broader Manning drought response strategy, the treatment capacity of the Nabiac Water Treatment Plant needs to be increased from 12 megalitres per day to 18 megalitres per day.

There are also no backup measures in place to protect against the failure of key components at the plant. This could have significant consequences during a drought event if the plant was unable to continuously produce treated water.

An additional raw water feed pump and two additional membrane filtration racks will be installed and a number of modifications will be completed to ensure the plant can treat up to 18 megalitres per day.

Several key components will also be duplicated to ensure the plant can continue to run if an existing component fails. This will involve the construction of a second pre-treatment tank and aeration tower and a second treated water reservoir, along with the installation of a second membrane treatment system.

Increasing the capacity of the Nabiac Water Treatment Plant will improve the drought security of the Manning Water Supply System and reduce the community’s reliance on the Manning River as its primary water source. Duplicating key components of the plant will also improve its operational reliability and ensure it can continue to supply water to the community if a failure with an existing component occurs.
