Water Efficiency Improvement Projects

Mareeba Dimbulah

The Mareeba Dimbulah water supply scheme was established in 1958 upon completion of the Tinaroo Falls Dam, to provide water to the Barron Gorge power station. Today the scheme supports more than 1000 irrigation, industrial and urban customers with a total of 204,424ML in water entitlements.

Works on the Mareeba Dimbulah Water Supply Scheme will comprise six sub-projects to improve operating efficiency and reduce water losses by up to 8,000ML, which will boost the local economy by providing more water access for irrigators.

Total project cost is $28 million, of which SunWater will invest $16.4 million to supplement National Water Infrastructure Development Fund funding of $11.6 million.

What’s involved?

  • Sunwater will construct approximately 4.5km of pressurised pipeline, creating an additional three balancing storages with capacities of 200ML, 100ML and 5ML, as well as installing 25 automated gates in key reaches of the channel system.

Major milestones

  • Design Completion – Early 2019
  • Construction commences mid 2019  with a planned completion date of mid 2021.

Location

Mareeba / Dimbulah, North Queensland.

 

Nogoa Mackenzie

The Nogoa Mackenzie water supply scheme was established in 1968 to meet agricultural and mining developments and the water requirements of associated urban communities in Central Queensland. The scheme supports 387 customers and more than 70 percent of its water entitlements are held by irrigators.

The Nogoa Mackenzie water supply scheme will benefit from channel re-lining to 34km of the Selma Channel system, which will dramatically reduce seepage losses currently occurring in the irrigation channel.

Total project cost is $11.7 million, of which SunWater will invest $8.7 million to supplement NWIDF funding commitment of $3 million.

What’s involved?

  • Initial estimates are that approximately 6,000ML of additional water entitlement will be made available for customers to purchase.

Major milestones

  • Design finalisation mid 2019
  • Construction works to align with Customer requirements.

Location

Nogoa / Mackenzie, Central Queensland.
