Biosolids field day at Longwarry hosted by South East Water

May 14, 2019 @ 10:00 am - 12:30 pm

A first in Victoria! Come and see our bumper crop of summer forage sorghum produced from liquid injection of biosolids under dryland conditions.

  • Challenge your thinking about novel ways of using valuable resources in biosolids.
  • Let’s talk about latest technologies and future interventions.
  • Network with water industry, soil and environmental professionals, farmers and regulators.

Finding innovative use of biosolids in agriculture is always challenging. Current regulation for application of biosolids is to surface broadcast followed by shallow incorporation. At South East Water, we recently received approval from the Victorian EPA to trial soil injection of liquid biosolids (treatment/stabilisation grade T3) for improving soil structure, fertility and function at our Longwarry Water Recycling Plant.

Soil injection of liquid biosolids in agriculture has been practiced in Australia since 1998; the majority of which has occurred on farms in the Sydney region only. Liquid food wastes have also been soil injected into agricultural land for over 20 years in New South Wales, and more recently in northern Victoria.

The farm at our plant is under recycled water irrigation (80 ha) for the production of fodder crops (maize and pasture). Around 20 ha is dryland farming.
