The scheme did not receive government approval until 1995; around the same time, there was further reorganisation of the water industry, with the Environment Agency replacing the National Rivers Authority. Although Mr Ackers' concerns had not been addressed, it commissioned the design and construction of the scheme as originally conceived, at a cost of £110 million. Throughout the planning process, from initial feasibility studies to delivery of the project, Lewin, Fryer and Partners were the consulting engineers. Principal works were the creation of the channel, various flow control mechanisms and bridges for road, rail and foot traffic.
