Project summary

Edit project overview to modify the project summary.

The main aim of the Quercus project is preventing crime. This part of the project restores an historic feature on the river and incorporates a settling tank to contain sewerage overflows following heavy rainfall, which could previously have contaminated the river. On top of the settling tank, a small riverside open space is being created. Opposite the Bastion itself, improvement works were being carried out to the banks and shallows, to create wetland habitats and wildlife corridors, known as ecological linking zones.
