Canvey Island barriers spanning Benfleet Creek to the north and East Haven Creek in the west. The drainage system consists of sewers, culverts, natural and artificial dykes and lakes which feed seven pumping stations and gravity sluices that discharge the water into the Thames and creeks. Four of the discharge sites are "high flow" stations capable of discharging 600 litres of water per second at any tide level. The levels within the system are managed by a further five "low flow" pumping stations. The Environment Agency's Thames Estuary 2100 flood defence plan includes Canvey Island as one site for alleviating the flood
Canvey Island Independent Party Canvey Island Independent Party The Canvey Island Independent Party (CIIP) is a local political party active on Canvey Island, in Essex, England. It was established in 2004 to campaign for a separate district council for Canvey Island. Canvey Island became a single civil parish in 1881, replacing 17 former divisions that had existed in broadly the same form since the Norman era. In 1926, the parish was converted to the Canvey Island Urban District, which governed the island as a distinct entity. The Urban District was dissolved along with the mainland Benfleet Urban District in the Local Government Act 1972
