WWT Consulting undertook feasibility studies, concept and detailed design for a wetland treatment system for landfill leachate at Shaw Forest Park, Swindon. The system was designed to treat leachate from a perimeter ditch around the landfill site, prior to discharge to a stream.
A multi-cell design was required to overcome site constraints, which included a high voltage electricity cable and sewer running through the centre of the site. A settlement pond, wet grassland (for ammonia removal) and a series of different plant communities were incorporated to maximise treatment and attenuate stormwater. A wildlife pond provides final polishing and added biodiversity value to the treatment system.
The design also had to incorporate public access to the site. A community pond at the outfall was included and will be planted and maintained by local community groups.
