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, seven kilograms of biosolids are created as each household’s sewage is broken down at Barwon Water treatment plants.

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

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