This is the redevelopment of a former plating plant near Heathrow Airport. The soil is contaminated with heavy metals, and to prevent this from polluting the groundwater a semi-permeable bentonite barrier surrounds the site which allows water to percolate through but traps the heavy metals.

The following SuDS components were used on this site:
