Project Announcement – Gas Chlorination and Ultraviolet Disinfection, QLD


WestWater have won a project for a QLD regional council to upgrade one of their water treatment plants via the implementation of gas chlorination and ultra violet disinfection practices.

The site presently draws water from 3 x bores, dosing sodium hypochlorite and fluoride on route to a 450KL reservoir. From there the town is supplied via a quad booster pump station. Due to the water source being supplemented by open water runoff and the unreliability of the current sodium hypo system, this has prompted the council to improve the process.

The upgrade will incorporate design & construction of a brand new, AS2927 compliant transportable gas chlorination building and duty/standby UV system with the capacity of reducing virus by log 0.5, cryptosporidium and giardia by log 4. The addition of these reliable and assured systems will heighten the councils defence against water born bacteria and virus, ultimately providing a high quality output to its patrons.

All aspects of the works will be completed in accordance with the Contract and Australian Standards.

The project is expected to reach Practical Completion in June 2022.
