APMCTM

• Demand Driven. Advance Pressure Management and Control (APMCTM) is a method to modulate the outlet pressure of the PRV base on requirement.

• APMC consist of a sequence of works

• Studying the overall system

• DMZ/PMZ Survey

• Pressure survey

• Hardware: Loggers, Regulators, Management and Control Systems

• Database Management, Pressure Management, Maintenance and Ground Respond Works.

BENEFITS OF PRESSURE MANAGEMENT

• Stable pressure in the system

• Lower burst frequencies

• Lower leakage levels

• Leakage intervention reduced. Active leakage works reduced

• Prevention of water hammering and surge• Prevention of water hammering and surge

• Longer lifespan of pipes

• Improve water quality

Control

- Reduction in physical losses

- Prolong intervention period

- Monitoring of leakages and

burst via installed system

- Longer lifespan of pipes

- Lower burst frequencies

- Monitoring of

leakages and burst

via installed system
