Pump Regimes

University of Kent at Canterbury The supply regime created recurring bursts on the distribution network as pumps operated on a simple reservoir level drop control mechanism.

The violence of the start up caused pressure surges in the mains giving rise to regular leaks.

Re-modelling the control regime and changing the pump sets allowed for a much slower and smoother start up.

This, along with continuous flow and pressure monitoring at the revenue meters gave reliable nightline profiles that were then used as the basis of focus for baseline reduction.

Consumption savings equivalent to £21k per annum have been achieved for a modest investment of £8k. Rationalisation of the distribution network has optimised the fire fighting facilities and reduced the number of ‘dead legs’ thus reducing the risk of Legionellosis and other bacteriological growth.
