Utility reports average the grid — not your home

Dulwich'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.
