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
River, Estuary and Coastal Observing Network general public. Information disseminated through the website includes concise definitions of water quality parameters measured and how to interpret trends in water quality at high resolution. To maintain data quality control, water samples are collected to validate instrument settings and readings with traditional wet-chemistry methods. Water samples are analyzed by a state-certified Florida Department of Environmental Protection laboratory in Tallahassee, FL. SCCF plans to maintain the observing systems for the next three years or more, depending on funding.
