Treatment plant upgrade delivers even better water reliability for the Lower Hunter
Upgrades have now been completed at our largest water treatment plant, which will result in even better water supply reliability for our community, particularly as we approach the warmer months.
Grahamstown Water Treatment Plant has undergone extensive remediation work to replace old sedimentation rakes used to clear sludge from the raw water, helping to improve the plant's operating efficiency. The new submerged collector systems are now operational in all four tanks and remediation works were undertaken to the concrete infrastructure.
Project Manager Lorenzo Sposito said water reliability is crucial to the community and we are always looking for ways to improve our processes.
"It's a fantastic result for Hunter Water to successfully complete the system upgrade prior to summer as this is a period in which we see an increase in customer demand."
The new sludge collection system, made from high quality stainless steel, is lighter and simpler than the previous 12 tonne rake system commissioned in 1976.
Hunter Water delivered the project with the construction works carried out by Abergeldie Complex Infrastructure.
