The ability to accurately control pressure is a central aspect of operating any water network. Pressure needs to be consistently high enough to satisfy the customer, yet excessive pressure drives up leakage, burst frequency, energy consumption, and operational costs. The challenge of accurately controlling pressure is complicated by the fact that demand can fluctuate hourly, daily and seasonally.
Efficient pressure management lowers operating expenses by reducing the number of events requiring site visits, while maintaining adequate pressure for customers. Pressure management combines the installation of pressure loggers, Pressure Reducing Valves (PRVs), variable speed pumps, optimisation systems and other equipment with their respective control software. Since leakage is directly related to pressure, any reduction in pressure will result in a proportional reduction in leakage levels. With reduced pressure and leakage, utilities can in turn save energy and money by pumping less water.
