water. To use potable water for industrial use is undesirable considering the scarcity of water and the volumes of water required

for industrial use in the SEZ. It is essential that a CDC provide the required water to investors to operate effectively. Due to the

high water demand it is essential that the Return Effluent (RE) solution be constructed to ensure that RE can be provided for

industries and ensure that the potable water reserves of the NMBM are protected.

The proposed return effluent scheme involves refining effluent (sewerage) from the Coega New Wastewater Treatment Works

and its conveyance via pumps, pipelines and storage reservoirs to the Coega Special Economic Zone (SEZ) to Zones 3, 4, 5, 6
