North West Coastal Groundwater
The North West Coastal groundwater scheme could be located North of the existing Neerabup coastal groundwater scheme, parallel to the coast. The groundwater is located in the outer perimeter of the Gnangara Mound. There is potentially a yield of 28 gigalitres a year from the superficial aquifer which drains to the ocean.
The scheme would require treatment prior to distribution to customers. This source is located close to future North West corridor growth.
The Department of Water is currently preparing a draft Water Management Plan for the Gnangara Mound, which is expected to consider the reservation of groundwater from this area for public water supply.
Consideration needs to be given to the social and environmental impacts that may result from developing the borefield in conjunction with private land developments.
The scheme includes some water from the superficial aquifer, which may be adversely impacted by climate change.
