Catalyst - Water Recycling

Can we trust science to keep our water safe to drink? Drought, increasing populations and shifting rainfall patterns are placing ever greater demands on our water supplies. But what about all that precious liquid we flush away - can our waste water be safely recycled for human consumption?

In south-east Queensland a controversial multi-billion dollar scheme is recycling water from treated sewage. Supporters of the initiative believe it will provide a much needed boost to urban water supplies. But critics claim the technology can’t guarantee the water is clear of dangerous contaminants. Mark Horstman wades into the debate to see how recycled water is made safe enough to drink.
