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
