Wastewater Treatment Services

Mareeba Shire Council provides wastewater treatment services to the townships of Mareeba and Kuranda to prevent public health issues and to protect the health of our waterways.

Our wastewater treatment plants receive wastewater from residential dwellings, commercial and industrial operators, where the wastewater is mostly made up of water but also contains anything that is washed down kitchen sinks, toilets and into the sewerage system. Wastewater can contain food scraps, dirt, detergent and human waste.

Our treatment plants are designed to remove the contaminants in these wastes like nitrogen and phosphorus that can pollute our waterways and minimise the human exposure to diseases like cholera. Biological and chemical treatment process are used to clean the wastewater so that it can be discharged to the environment.

That is why it is important to think about what we wash down into our sewer system because it can kill the bacteria and microbes that are cleaning our wastewater.

Kuranda Wastewater Treatment Plant, Arara Street Kuranda

The Kuranda Wastewater Treatment Plant (WWTP) is an activated sludge plant which utilises the processes of aeration and sludge settlement to produce a high quality effluent.

Wastewater is received at the treatment plant via the Kuranda sewerage network. The influent (untreated wastewater) enters the Inlet Works where the solid and liquid streams are separated.

The wastewater is then treated in the Bio Reactor to remove organic matter (suspended solids and BOD, phosphorus and nitrogen) from the influent wastewater using biological and chemical means. The products of this process are treated effluent, waste activated sludge and nitrogen gas.

The effluent (treated wastewater) from the Bio Reactor is then settled in the Clarifier, pH adjusted, disinfected and the chlorine removed prior to release to Jumrum Creek (a tributary of the Barron River).

Bacteria and microbes are the primary treatment process at this treatment plant and as such their health and effectiveness is diligently managed by our Wastewater Operators. Our Operators manage the bacterial treatment in a number of ways including water quality monitoring, returning and wasting sludges, and maintaining optimal physical and chemical conditions.After successfully receiving a subsidy under the Queensland Government’s Local Government Grants and Subsidy Program for 2015 / 2016, Mareeba Shire Council will be upgrading its sludge management system. Council will be upgrading from the existing lagoon system to a new belt filter press that will dewater sludge efficiently. This will reduce our environmental risk and produce even cleaner effluent.

Mareeba Wastewater Treatment Plant, Hickling Avenue.

Through the generous grants and subsidies provided by both the State and Federal Governments, Mareeba Shire Council will be commencing the construction of a new Rising Main, Inlet Works and an upgraded Wastewater Treatment Plant in 2016.

These works will provide the much needed critical infrastructure upgrade to the current Trickle Filter wastewater treatment system and provide a significant environmental outcome for the Mitchell River catchment.

The new treatment process will consist of a 2 staged new Sequence Batch Reactor (SBR) with future capacity to convert to a membrane activated sludge treatment process (MBR). The bioreactor will be initially sized to provide a 12,500 equivalent persons capacity with an average dry weather flow of 3.8ML/day and then in Stage 2, the ultimate 16,000EP capacity (5ML/day) when converted to an MBR.

This major infrastructure project will serve to provide a sustainable wastewater treatment service for the community of Mareeba now and capacity build for the future growth; complimenting the upgrade of the Mareeba Aerodrome and growth within the Mareeba Industrial Estate.
