  • A water clean-up project costing an estimated £70 million has started at Shell UK's Stanlow plant - the UK's largest combined oil refinery and chemicals manufacturing plant. The first phase will be completed by the end of 1993 and involves the construction of 18 miles of on-site pipework to separate the three waste water streams and the installation of three dissolved air flotation units. Shell hopes that this will bring its discharges into channels feeding the River Mersey below the NRA's current standards all of the time. In the second phase, from 1995 to the end of 1996, a £35 million biological treatment plant will be built to neutralise most remaining traces of oil or dirt, achieving a standard of 5mg/l for oil compared to the present 10-20 mg/l and a biological oxygen demand of 10-20 mg/l compared to 20-30 mg/l.
