Cassowary Coast Regional Council

Water Treatment Water Treatment

Council owns and operates a water treatment plant in the Innisfail region.

This plant was built in 1933 and upgraded in 1972 and 1993.

Water is taken from the North Johnstone River, which is usually low in turbidity, alkalinity, colour and bacteria (except in times of wet weather).

The water goes through a process of chemical dosing, coagulation, flocculation, clarification, filtration and disinfecting (using sodium hypochlorite) before distribution via a 12" main to Council's main reservoir at Stoters Hill, Palmeston Highway.

The Innisfail water treatment plant serves a population of approximately 15,000 people in the Innisfail township and the Wangan, South Johnstone, Moresby, Mourilyan, Etty Bay, Mundoo, Jubilee Grove Estate, Flying Fish Point, Darradgee, Upper Darradgee, Garradunga and Eubenangee districts.

Other river intakes (gravity intakes with disinfection) are:

  • Nyletta Creek for distribution to Silkwood, Kurrimine, El Arish, Bingil Bay and North Mission
  • Bulgun and Boulder creeks for the townships of Tully, Wongaling Beach, Tully Heads and Hull Heads
  • Meunga Creek for Cardwell.

All of Council's drinking water supplies are disinfected with sodium hypochlorite and sampled regularly for compliance with Queensland State Government Regulations (i.e. Qld Health and Queensland Water Regulator requirements).
