Rothesay tank on the move

19 June 2000 10:04 - BAM Nuttall Ltd

A storm attenuation tank will shortly be floated across the Firth of Clyde to the scenic Isle of Bute as part of the Rothesay Sewerage Scheme, which is being undertaken by Edmund Nuttall Ltd on behalf of client West of Scotland Water Authority.

This £4.5 million project provides for the design and construction of two pumping stations, a rising main and outfalls, which will be connected to a wastewater treatment works.

The storm attenuation tank supplied by B&M Plastics of Bromborough will be located at Albert Pier in Rothesay, which is adjacent to the town’s busy harbour in an area that is heavily dependent on fishing and tourism for it’s livelihood. The tank is actually three high density polyethylene structured wall tanks, which have been interlinked to provide the required 1350 cubic metres of storage capacity. The total length of the tank is around 70 metres, and its weight is approximately 125 tonnes. Once towed into position, the tank will be sunk into a previously dredged bed to prevent any interference with the shipping channels, and also to ensure that the outstanding beauty of the area is not affected. It will then be surrounded by a concrete perimeter wall providing the toe support for a rock armour spending bench, which will cover the tank.

Nuttall started work at Albert Pier in late February 2000, with the demolition of the existing pier. The tank excavation and installation are due for completion by the end of June 2000.
