Barwon Water Biosolids Management Geelong, Victoria, Australia
The project involves the design, construction and operation of a fully enclosed thermal drying facility for the treatment of biosolids; a by-product of the treatment waste water and sewage.
The facility treats the biosolids to the highest possible T1 treatment grade. The Plenary solution also involves the beneficial use of these treated biosolids – suitable for farm fertiliser or fossil fuel replacement.
This was one of the first projects to be delivered under the Partnerships Victoria framework for a local water authority, Barwon Water.
Extensive consultation processes resulted in community criteria being written into the contract with Plenary Environment. The outcome was the selection of a thermal drying facility that:
- is fully-enclosed with zero odour beyond Barwon Water's fence;
- is no taller than the existing buildings at the Black Rock water reclamation plant;
- produces the highest treatment grade of biosolids possible;
- has no visible air emissions; and
- includes substantial investment in landscaping and aesthetics.
The facility replaces the practice of transporting biosolids 80 km by truck to another facility for drying, and so, has reduced the number of heavy trucks on local roads by 1000 truck movements each year.
