Anglian Water is saving around £2,000 a year on a borehole pump’s electricity costs following an energy assessment.

The £7,000 project, which is expected to pay for itself within three and a half years, saw the installation of an ABB variable speed drive (VSD) on a submersible pump motor.

The borehole is one of two operated by the water company, at Blackhouse Lane and Woodhall Road, that feed the reservoir serving customers in Sudbury, Suffolk.

Prior to fitting the VSD at Blackhouse Lane, both pumps ran at fixed speed all of the time but had to be turned off frequently as the reservoir reached the desired capacity.

The system was inefficient as it was pumping more water than needed.

The VSD has helped reduce the amount of energy used by the pump motor, resulting in the savings.
