SW water use to double by 2060

Demand for water in the South West could outstrip supply in less than 50 years, according to a draft water management plan released by the Water Corporation this week.

The Water Forever South West report predicted double the number of people would rely on the department for water by 2060.

Population increases coupled with a drying climate lead to the department considering the source of water supplies over the next 50 years.

The Department expects water demand could increase by 200 billion litres by 2030 with water availability decreasing by 25 per cent.

“We expect the capacity of the Capel and Dalyellup scheme will need to be increased in about five years depending on population growth and water use efficiency, followed by Eaton-Australind around 2030, ” the report said.

The report refers to 31 South West towns where the Water Corporation manages water supply.

It excludes Bunbury and Busselton which have an independently managed water supply.

Water Minister Mia Davies said the 50-year plan and options for water supplies was important because of the drying climate and growing population.

Ms Davies said drinking water supplies for the South West were secured in the medium term but by 2060 the demand for water could surpass supply.

“The draft plan details options and opportunities for developing new water sources, reducing water use and increasing water recycling, ” she said.

Dardanup shire president Mick Bennett said early discussions had taken place about water services to the planned East of Eaton development that could house 70,000 people by 2050.

Cr Bennett said the location had been selected with the provision of services in mind.

The report noted a Dalyellup groundwater treatment plant upgrade and expansion to the Bunbury Yarragadee groundwater infrastructure as possible solutions.

Other solutions could include micro seawater desalination plants, water carting, new groundwater sources and better catchment management.

The draft report is open to public comment until December 16.
