The tidal Thames and estuary is an area recognised for its environmental importance. It is home to many hundreds of thousands of over wintering birds every year, 129 different species of fish, four special protection areas and eight sites of special scientific interest. We take account of these environmental sensitivities in all our functions and activities. Discover the environmental characteristics of the Thames and its estuary and the work we are doing to enhance conservation and sustainability.
The Silt Lagoons cover 152 hectares and are located to the south of Rainham town centre, between the Rainham to Thurrock railway lines and the river. This area lies on the flood plain of the Thames and is located within a meander of the river channel. The Lagoons, which are raised above the surrounding ground level, are bounded to the north by the A13 and to the south by a landfill site operated by environmental services company, Veolia.
