A water recycling plant at the Millennium Dome

The water recycling treatment plant at the Millennium Dome in Greenwich is the largest of its kind in Europe and a showcase for water treatment processes of the future. It is designed to provide 500 m³/day to flush all the toilets and urinals in the Dome. The water is ‘reclaimed’ from three sources—rain water from the Dome roof, greywater from the handbasins in the Dome and groundwater from a borehole on the site. This paper describes the development from the design stage through to construction of this unusual engineering project, and details the water treatment processes in use in the plant.
