Twycross Zoo Wetland Treatment System
Twycross Zoo - East Midlands Zoological Society Ltd
East Midlands, UK
WWT Consulting designed a comprehensive approach to effluent treatment for the zoo. Wetlands were used as part of the exhibit landscaping to treat water and return it for reuse within exhibits. A larger 1.6ha wetland system was designed to treat the visitor effluent whilst providing adequate storage for an extreme rainfall event.
The major wetland system comprised 19 ponds with plant communities ranging from reedbeds, to marshes to open water habitats. In addition to the wastewater treatment function, the wetlands were also designed to provide the zoo with a native wetland biodiversity exhibit.
