Mid Congress Tours

A day tour to look at aspects of groundwater use and groundwater issues is offered for Wednesday 18 September following the Darcy Lecture. Buses will depart from the congress venue at 10.30 after morning tea and return at 17.00.

Date: Wednesday 18 September 2013
Costs: Delegates may select one mid Congress tour inclusive of the registration fee for full and student registration categories. Includes return coach transfers from PCEC, lunch and afternoon tea
Time: 1030 – 1700

ALL tours will cover the following:

  • the geological context of the Perth Basin and its three major aquifers;
  • the use of groundwater for public water supply and for irrigation of public and private lawns and gardens;
  • the effect of urbanisation on the hydrological cycle including the recycling of stormwater and water sensitive urban design
  • throughflow wetlands and climate change in an urban context; and
  • issues of groundwater quality change and contamination.

Each tour will have an additional focus on one particular aspect of the hydrogeological environment of the Perth area.

1 . Adapting Perth’s Water supply to a Drying Climate

Our drying climate has greatly increased Perth’s reliance on groundwater over surface water. This tour will go to the public water supply borefields in the urban area and on the Gnangara Mound, an area of native bush and pine forest reserved for public water supply, including a visit to a water treatment plant.

2 . Managing Groundwater Over-allocations

This tour will look at public water supply borefields and domestic groundwater use, and use for horticulture in the northern fringes of the urban area, visiting a market garden on the fringe of the Gnangara Mound, and discussing the regulation of groundwater abstraction.

3. Gnangara Mound Wetlands and Climate Change

This tour will visit a number of ecologically significant wetlands which have fluctuated in water level with climate variability over the last 6 – 8000 years. These systems have however been exposed to greater changes over the last 150 years. This tour will look at causes of water regime changes and the consequences for vegetation and ecology. It will also look at management options to retain water over the summer period especially

4. Managed Aquifer Recharge Innovations in the Perth Basin

This tour will visit the Beenyup Managed Aquifer Recharge project in Perth’s northern suburbs where wastewater treated by reverse osmosis is being injected into the confined Leederville aquifer, one of Perth’s three main aquifers.

5. Perth Basin Geothermal and Groundwater Resources

The Perth Basin is highly prospective as a geothermal resource and for water supply. This tour will go to a number of sites using both the shallow water table aquifer and the 1000m deep Yarragadee aquifer. It will also explore some of the potential conflicts between using a single aquifer for both energy and water resources and the opportunity of using geothermal energy to desalinate brackish groundwater.

6. Contaminated Sites of the Swan Coastal Plain

This tour will go to a range of sites in the Perth area where groundwater contamination has occurred from both point and non-point surface disposal of a range of contaminants on the sandy coastal plains soils.
