Critical Refill Control System, Rutland Water
For Anglian Water Services
Business Challenges
230,000 cubic meters of water are extracted from Rutland Water daily, so an equal amount has to be extracted from the feeding rivers.
Rutland Water is refilled from local rivers, the River Nene and the River Welland, using automated abstraction methods. Like all water companies Anglian Water is under increasing pressure to operate as efficiently as possible; alongside commercial pressures there are important environmental issues influencing the way it operates. Water is no longer a commodity that can be taken for granted and operations need to adapt to reflect this.
The old automated abstraction systems on these two feeding rivers were dated and unable to provide the flexible and efficiency required by Anglian Water.
To comply with regulatory requirements, achieve flexibility and improved abstraction efficiency Anglian Water decided to invest in a new control system for both rivers.
How We Helped
Capula was selected by Anglian Water to supply, install and commission a new control system to manage the extraction of water from the two rivers feeding Rutland Water. The new system not only provides improved extraction efficiency, it also offers greater flexibility in the volume and frequency of abstraction, enabling Anglian Water to operate in a more environmentally sensitive way.
Included in the project were 4 pumping/abstraction stations and a reservoir level control. Each pumping station has between 5 and 11 large pumps with both fixed speed and variable speed in duty/standby and assist modes. The 4 stations, reservoir and main treatment works are linked via telemetry units to provide complete control of the water abstraction, delivery, reserve and quality.
