Advice
Practical tips for residents
Chlorine Levels Are Low
Chlorine in Commissariat Point measures 0.1 mg/L, which is low. Filling a jug and letting it stand for 30 minutes will reduce any residual taste.
Flush After Absence
If your home has been unoccupied for several days, run the kitchen tap for 30 seconds before drinking. This clears stale water that has been sitting in pipes.
Use Cold Water for Cooking
Always draw cold water for cooking and drinking. Hot water systems can leach metals from pipes and fittings, and cold water has less dissolved material overall.

Utility reports average the grid — not your home
Commissariat Point's water meets ADWG standards at the source, but old pipes, roof tanks, and ageing plumbing can add lead, copper or bacteria before the water reaches your tap. These won't show up in your utility report.
Check your own tap before buying a filter or assuming the suburb average matches your home.
