Water Treatment Plants receive grading

The Mount Grand and Southern Water Supply systems have been officially graded by the Ministry of Health with a final grade of 'Ab'.

The 'A' is the grading for the Water Treatment Plants and means 'completely satisfactory, extremely low level of risk.' The 'b' is the grading for the watermains network and means 'satisfactory, very low level of risk.'

"This means that 83% of the city's water consumers receive 'A' grade water," said Water and Waste Services Manager, John Mackie.

The assessments are risk-based and are a measure of confidence that the drinking water supply system will not be contaminated, rather than an indication of water quality coming out of your tap at any given time.

Work first began to upgrade the facilities in 1995. Grading usually takes place two to three years after construction is complete, as a minimum of twelve months satisfactory performance of the plant has to be achieved as part of the process.

The $64 million project was completed on time and on budget.

Water and Waste Services Production Manager, Gerard McCombie, commented "This project involved significant investment by the community and effort from consultants, contractors, our staff and Public Health South officials so the grading is great news and a great credit to all involved."
