Science The Key To Help Preserve Perth Green Spaces

  • Investigations help plan for sustainable management of Perth’s groundwater

Water and Science Minister Dave Kelly announced the start of a series of groundwater investigations that will help maintain the city’s green spaces, so they can continue to be enjoyed by future generations.

“It is no secret that Western Australia is becoming hotter and drier. Since the 1970’s, Perth’s rainfall has declined by more than 15 %.” Minister for Water and Science Dave Kelly said.

“McGowan Government understands that our drying climate has increased pressure on available water resources for a range of uses including drinking water supply, local horticulture and the irrigation of green spaces.”

Department of Water will this week conduct two geophysical surveys at Lake Monger Reserve to investigate underlying aquifers and groundwater movement. 

Surveys involve two-dimensional seismic and electrical resistivity imaging. Lake Monger is the first of several survey sites including UWA Sports Park and Shenton Park Field Station.

Work is part of the Western Suburbs Managed Aquifer Recharge and Kings Park Formation Investigation Program, which is being run in partnership with the Western Suburbs Regional Organisation of Councils and the Town of Cambridge.

Objective of the program is to better understand the effects of groundwater use and explore the option of pumping highly treated wastewater or stormwater into the aquifers for later re-use.

“That is why these scientific investigations are important to identify new ways to maintain urban green spaces, reduce urban heat and help ease pressure on public water supply schemes.” Mr. Kelly said.

“Scientific investigations and research will also help us develop new ways to store and recycle stormwater and wastewater, two important strategies in addressing the State’s climate challenges.”

Program also includes installing groundwater monitoring bores up to about 300 metres deep.

Surveys are temporary, non-intrusive and pose no threat to pedestrians, the environment or adjacent properties.
