Abstract:

The Salford Quays in Greater Manchester in the north west of England is a prestige commercial and residential development, built on the site of the old Manchester Docks. Water quality is poor and results in environmental problems including gassing and odours. The main cause is the low oxygen level and water stratification in the slow flowing canal.

The project is designed to raise the oxygen levels by pumping oxygenated canal water from four locations into the Quays. Oxygen is provided from a single oxygen store through pipework attached to the quay walls and is drawn by venturi into the pumps. The oxygen input is up to 15 tonnes per day and the target concentration in the canal is 4 mg/l of dissolved oxygen.

The project is being financed and managed by the utility North West Water with support from the UK National Lottery Fund. It is backed by a consortium of interested parties including the UK Environment Agency, local authorities, the Manchester Ship Canal Company, the Lowry Trust and public agencies. Construction is expected to be completed by summer 2001.
