What are biosolids?

When sewage is treated, micro-organisms digest the sewage, breaking down the organic material. Two products are created – recycled water and biosolids.

Each week, five and a half kilograms of biosolids are created as each household’s sewage is broken down at Barwon Water treatment plants.

That is enough biosolids to fill Skilled Stadium to a depth of one metre every year (54,000 tonnes).

Before drying, biosolids are 85 per cent water and look like mud.
