3. The Mullumbimby Water Treatment Plant

The Mullumbimby Water Treatment Plant (WTP) is operated by Council, and provides drinking water to residents in the Mullumbimby township that is treated, filtered, and disinfected.  The drinking water supply is sourced from Wilsons Creek via the Lavertys Gap Weir. Water flows to the plant by gravity through a heritage-listed race, via a mountain tunnel.

The Mullumbimby Water Treatment Plant is a pressure sand filtration plant, providing drinking water that undergoes full treatment.

Treatment consists of coagulation and flocculation using aluminium sulphate. The water is then passed through the filters and chlorine is added as it leaves the clear well, providing a two barrier protection.  The Mullumbimby water supply is not fluoridated.

Byron Shire Council is committed to managing its water supply catchments, treatment plant and supply assets to provide safe, high quality drinking water, which consistently meets or exceeds the Australian Drinking Water Guidelines (ADWG) 2011, consumer satisfaction and other regulatory requirements.

Council purchases bulk water from the regional water supply authority Rous County Council.  Rous Country Council provides drinking water to seven reservoirs in the Byron Shire from the Nightcap WTP.  The Nightcap WTP is operated by Rous County Council and provides treated, filtered and disinfected water for distribution to Byron Shire residents. The drinking water supply is sourced from the Rocky Creek Dam.  Under the Water Supply Agreement we are responsible for maintaining water quality in the reservoirs and reticulation system.

4. Fluoride and the water supply

Byron Shire Council resolved in 2005 not to add fluoride to the water supply and reconfirmed this commitment in November 2013.
