Meeting future chlorination demands, whilst
maximising operator safety
Allanooka is a gas chlorination plant that disinfects the groundwater from a borefield suppling Geraldton. Considered a major regional city, Geraldton
is approximately 300km north of Perth with a population of 38,000.
The client, the Water Corporation, wanted to modify the existing chlorination system to ensure that future chlorination requirements will be met. TRILITY was
contracted to design, supply, install and commission the chlorine system. The scope included new duty/standby reservoir inlet and outlet flow-paced chlorine
dosing, chlorine residual monitoring and outlet flow monitoring. Additional SCADA and electrical works allowed for an on-site generator to be connected to the
chlorination module such that the chlorination plant automatically switches over to generator power in the event of a power failure. Once power is restored, it
automatically switches back to mains power. All of this occurs without the need of an operator to attend site.
To meet the client’s stringent safety requirements withdrawable injection quills were installed which significantly improve operator safety when injecting
chemicals. The quill is designed so that it cannot be accidentally withdrawn or ejected. It is mechanically impossible for the quill to pass through the seal
chamber and therefore cannot become a projectile. In addition, chemical barrier solutions were installed at the new chlorine dosing points to protect operators
from the risks of chemical exposure.
To ensure a smooth handover of the plant to the Water Corporation’s operations team, TRILITY provided training for the plant operators which included the
provision of all operations and maintenance manuals.
The site works included civil and structural works which were undertaken during COVID-19 restrictions, severely limiting the number of people that could be
involved on-site. In fact, the whole project was successfully managed remotely without the client’s project manager ever stepping foot on-site.
The Allanooka gas chlorination plant reconfiguration has ensured that future chlorination requirements, whilst enhancing operator safety.
