Water Monitoring Strategy - NSW Coal Basins

The Water Monitoring Strategy for Coal Basins in NSW has been developed to improve our understanding of groundwater behaviour in the NSW coal-bearing geological basins.

The strategy aims to collect groundwater data to identify the potential effects of extractive industries on water resources in NSW coal basins.

As part of the strategy, we are expanding the monitoring network infrastructure to gather more information so we can better map, monitor and manage groundwater. The NSW Government has committed $22.8 million to deliver the strategy, which is due to be completed in 2020. When complete, the data will be made publicly available. Our fact sheet provides more information on the water monitoring network expansion.

In this video, Lead Hydrogeologist Doug Trudeau explains why we monitor groundwater, and takes us through the process of selecting sites and tells us what happens during drilling. Doug is on site in the Gloucester Basin with our drilling contractors, putting in one of our deeper bores – this one targeting a coal seam at about 350 meters below the ground.

Where are we up to?

  • Drilling works are almost complete with nearly 70 bores constructed in the Southern, Hunter and Western Coalfields, and the Gunnedah and Gloucester Basins.
  • The last remaining bores are currently being drilling in the Newcastle Coalfield.
  • Contracts are currently in place to equip the bores with water sampling pumps.
  • The bores will soon be ready to hand-over to WaterNSW to be installed with hydrometric monitoring equipment and telemetry.
  • Then monitoring can begin with data going to the WaterNSW web-site for the public to see.
