14 Organic Waste Recycling: Technology and Management

1.3.3 Werribee Farm, Australia


The Werribee Farm was established at the inception of the Melbourne Sewerage
System and has been in operation since 1897. It is situated in an agricultural
area 33 km from Melbourne and has a frontage of 21 km to Port Phillip Bay. Of
the Melbourne sewage flow received at the Farm, 70 percent is municipal waste
with the remainder coming from trade and industrial wastes. Table 1.3 shows
the infrastructure and facilities for sewage treatment, and data of livestock being
raised at the Farm.

Figure 1.7 shows the sewage purification and waste recycling schemes in
operation at Werribee Farm, consisting of three treatment processes, namely
waste stabilization ponds (or lagooning), land filtration (or irrigation) and grass
filtration (or overland flow). Sewage is primarily treated by a series of waste
stabilization ponds. Sewage irrigation through land filtration and cattle grazing
