WaterNSW has announced that newly installed dosing equipment is now operational at the Oberon Pumping Station, providing higher quality treated water to the Lithgow area. 

The Potassium Permanganate Dosing Plant at Oberon Pumping Station will reduce manganese levels and discoloured drinking water caused by seasonal changes to the Fish River water supply.

WaterNSW General Manager Regional Operations, Brian Mayhew, said that the company is excited to have this new equipment online as part of its ongoing commitment to providing the highest quality treated water it can for customers on the Fish River scheme in the Lithgow Council area.

“Potassium permanganate is commonly used in water treatment plant processes and will be dosed into the water supply in line with current guidelines,” Mr Mayhew said. 

“The Duckmaloi Water Filtration Plant already removes some manganese, and adding potassium permanganate to the raw water will improve the manganese removal during the water treatment process.”

In addition to the potassium permanganate dosing, WaterNSW will also trial ACH (another commonly used chemical in water treatment) to check if this further improves water quality for treated water customers. ACH will also be dosed in line with current guidelines from the Oberon Pumping station.

“This new system will allow us to respond immediately to seasonal changes which cause elevated manganese concentrations in the Oberon Dam, and most importantly, supply better quality water for our customers.”
