Narrative is taken from

The Hippo exhibit at Werribee Zoo has benefited from the addition of a wetland filtration complex which takes nutrient rich water from the enclosure and treats the water prior to recirculation. Australian Ecosystems collaborated with the Werribee Open Plains Zoo and Urban Initiatives PTY LTD in this project. Australian Ecosystems collected seed, propagated, planted and maintained to maturity approximately 70,000 plants for this project, which was awarded the Australian Institute of Landscape Architects Land Management Award in 2007.
