ON THE COAST
EARLY investigations for a possible seawater desalination plant in Alkimos will start next week with an offshore survey.
Water Corporation spokeswoman Clare Lugar said the survey was part of ongoing feasibility studies into a possible seawater desalination plant in the area.
“If constructed, the seawater desalination plant would form part of the metropolitan area’s Integrated Water Supply Scheme and predominantly service the city’s growing northern corridor,” she said.
“The Perth metropolitan area already has two operating desalination plants at Kwinana and Binningup, which together supply 48 per cent of Perth’s fresh water needs.
“An Alkimos desalination plant would be located next to existing wastewater treatment infrastructure within the Alkimos Water Precinct.
“No decision has been taken at this time to proceed with construction or when a new water source may be needed for Perth.”
The Alkimos testing will start about September 17 and continue to November, with three weeks of seismic testing initially followed by core-sampling of the seabed using a drilling barge that may be visible from the coast.
“The seismic testing will involve an exclusion area being off-limits to vessels and equipment to prevent entanglement,” Ms Lugar said.
“The seismic testing, which is non-invasive, involves collecting data from the seabed and subsurface geology through releasing pulses or sound waves.
“Once complete it will be followed by five weeks of core-sampling, which will involve drilling small holes into the seabed and extracting samples.
“During this second stage, the exclusion zone will be smaller, extending 25m around the barge.”
The testing will be in waters directly off Alkimos between Alkimos Reef and Eglinton Rocks, extending out about 5.5km from the coast.

Scheduled to open in 2021, Alkimos will be the first train station along the Yanchep rail extension and will form the focal point of the new Alkimos Central community.
The WA Planning Commission recently approved the structure plan for Alkimos Central, which will be a hub for a projected population of 60,000 in the fully developed Alkimos-Eglinton District.
Earthworks at LandCorp’s 212ha development east of Marmion Avenue will start in mid-2019, with a mix of residential, retail, recreational, entertainment and commercial uses planned.
“This will provide a boost of around 15,000 jobs in the northern suburbs, including construction jobs and new employment opportunities,” Premier Mark McGowan said.
“Alkimos Central will provide the focal point for up to 13,500 local jobs, while the construction of the Yanchep rail extension is expected to generate more than 1600 jobs.”
Transport and Lands Minister Rita Saffioti said Alkimos Central would serve as a destination to visit, work and shop.
“It will feature a significant retail area, mixed density residential development, business and service industrial precincts, plus a civic and cultural zone,” she said.
“There are also plans for district playing fields and an indoor recreation centre.”
Housing Minister Peter Tinley talked about Metronet precincts at a Committee for Economic Development of Australia conference this week.
“Metronet precincts will enable people of all ages and abilities to live in a range of affordable housing options in safe, inclusive and connected communities,” he said.
The recently developed Social and Affordable Housing and Jobs Package will also feed into Metronet to deliver 1390 homes.
