Critical Refill Control System for Anglian Water Services

Capula has delivered a Critical Refill Control System for Anglian Water Services (AWS) at Rutland Water.

Rutland Water is one of the largest artificial lakes in Europe, was constructed in 1976 and supplies water to one of the driest and most densely populated areas in the UK. The reservoir is not only used for water storage; it is also a popular water sports centre and nature reserve, managed by the Leicestershire and Rutland Wildlife Trust.

The new control system will enable AWS to extract water more efficiently from the two rivers that feed Rutland Water, the Nene and the Welland. 230,000 cubic metres of water are extracted each day from the reservoir so an equal amount has to be extracted from the feeding rivers to simply maintain the water level. As well as providing AWS with a very efficient extraction method the new control system also allows AWS to operate in an environmentally sensitive way, as the new pumps and system offer greater flexibility in the volume and frequency of abstraction.

The project was completed ahead of schedule and critically before the autumn rains, which meant AWS could take advantage of the higher river levels in autumn to refill the reservoir after two very dry winters.
