The 8.6km pipeline will link a reservoir in Mount Cotton with a reservoir in Logan City, allowing water to flow in either direction depending on the needs of the region.

About 700 metres of pipe have already been laid since work began last month, according to the Southern Regional Water Pipeline Alliance’s latest project update.

The alliance says workers are continuing to lay pipes through private property from the Kimberley Park Reservoir in Shailer Park to West Mount Cotton Road, Cornubia.

Clearing along West Mount Cotton Road to Gramzow Road, Cornubia, is now complete and pipe-laying will soon begin through this corridor.

The pipeline, due to be finished by the end of the year, will transport water between the Kimberley Park Reservoir and the Heinemann Road Reservoir.

Although the completion date for the Eastern Pipeline Interconnector is set at December 31, the pipeline is expected to be finished some time in advance to allow time for testing.

Construction of the mainland pipeline is continuing, despite the State Government’s decision last year to abandon a planned new borefield on North Stradbroke Island because of environmental concerns.

The project was expected to provide 22 million litres of water a day into the regional water grid if the new borefield was built.

However, the Queensland Water Commission now says 10 million litres could still be supplied from the Redlands each day by “maximising supply” from Capalaba’s Leslie Harrison Dam.

Existing water supplies from North Stradbroke Island would be maintained under the plan.

The State Government is due to take over ownership of Redland City Council’s bulk water assets on June 30. These include reservoirs, pumping stations, existing borefields on North Stradbroke Island and the Leslie Harrison Dam.
