WRc established economic relationships that demonstrated the long-term savings potential from Pressure Managemnt (PM) during AMP 2: Report 'UC 3325 Assessing the Long Term Economic Benefits of Pressure Management'. However, relationships between burst rate reduction and reduced pressures were not established because of lack of reliable data and therefore the potential benefit of deferment of asset renewal/replacement could not be assessed.
It is accepted that a well-managed PM strategy should allow a substantial reduction in Active Leakage Control (ALC) effort across networks, leading to considerable savings. To exploit this fully, however, the extent of the effect of the relationship with burst reduction needs to be better understood, analysed and defined.
In the last 5 years advances have been made by the industry in data collection and PM implementation. More detailed data on long-term performance, maintenance requirements and system configuration options, coupled with improved technologies, now allows for a clearer understanding of PM short and medium term impacts. Exploitation of this understanding will enable the industry to continue to improve implementation over the next five years and reap additional benefits from their Operational Network Management teams activities across the industry.
