Rous Water has announced an important change to its water treatment process.
The bulk water authority, which supplies the Ballina, Byron, Lismore and Richmond Valley Councils, is switching from chloramination (involving the addition of chlorine and ammonia) to chlorination (chlorine only).
The changeover will occur progressively from late February, and is expected to take about two weeks.
Chlorination is presently used for treating water in cities such as Sydney, Melbourne, Peth and Canberra, and regional centres such as Tweed Heads and Casino.
Chlorination has also been used for some time in towns like Nimbin, Mullumbimby and Wardell.
“While the Northern Rivers has long relied on chloramination to keep our water clean and safe, recent research conducted by Rous Water indicates that chlorine only will now provide a better outcome,” said Rous Water general manager, Kyme Lavelle.
“While most people won’t notice any change in what comes out of the tap, customers can be assured that the new treatment process will continue to meet stringent NSW Health Department guidelines.”
The changeover may require water to be flushed from the water mains in some areas, temporarily resulting in periods of low pressure. Mr Lavelle said Rous Water will attempt to minimise this where possible.
Rous Water is sending a brochure explaining the reasons for the change to consumers.
