About

Across the Wirral Operational Catchment there are 42km of River made up of five rivers - the River Birket, including Arrowe Brook and Fender, to the north and Dibbinsdale and Rivacre Brooks to the south. These rivers are fed by a number of small tributaries and all of these rivers flow into the Mersey Estuary. Land use in the operational catchment is a mixture of agricultural and urban. This is reflected in the water quality issues experienced on the Wirral caused by urban diffuse pollution from a combination of road run-off and misconnections, rural diffuse pollution and extensive physical modifications.
