Werribee Open Range Zoo Water for Wildlife

Werribee Open Plains Zoo

E2Designlab conducted two investigations for Werribee Zoo, a review of waterbody performance and management of the Hippo exhibit water system. These projects built on our previous experience working with Melbourne Zoo and Taronga Western plains zoo to assist in improving water management systems for the seal, predator and Lion exhibits.

The waterbody review involved extensive water quality and survey of existing vegetation conditions. Based on the review, recommendations for water quality and habitat improvement were made and prioritised.

The full water management system for the Hippo exhibit involved review of the treatment train, improvements to the wetland design and bathymetry, recommendations for sludge management and use of alternative water supplies. The scheme utilises multiple water sources including recycled water and river water, presenting a challenge for nutrient management and maintenance of a high standard of visual amenity. Water is circulated through the ponds and is then pumped through the wetland to provide water quality treatment; including suspended solid, nutrient and pathogen reduction. This system replaces the traditional water quality treatment systems, such as sand filters and chlorination, found in other zoos.

A UV disinfection unit, for further pathogen reduction, is also part of the treatment train. The wetland provides both water quality treatment for the water in the ponds as well as an opportunity for public education and interpretation about ecological systems and their role in water quality management. The recommended modifications were designed for ease of maintenance and for minimal disruption to visitors.
