Test results
Q: How is a DMA created?
A: By closing valves within the distribution pipe network to create a zone and installing flowmeters where valves are left open to register the volume of water supplied and removed from the DMA
Q: How is a DMA created?
A: By leaving open a few valves within the distribution pipe network and installing consumer meters to register water supplied to the DMA
Q: How is a DMA created?
A: By closing valves within the distribution pipe network and installing flowmeters to register water supplied to the DMA

A: Demand Metering Area
Q: What does DMA stand for?
A: District Metering Area
Q: What does DMA stand for?
A: Domestic Metering Area
Q: What happens with the control valve if network pressure gets too low?
A: The control valve will open to maintain the minimum network pressure
Q: What happens with the control valve if network pressure gets too low?
A: The control valve will close, stopping water from entering the network
Q: What happens with the control valve if network pressure gets too low?
A: The control valve does not respond to network pressure
Q: What is a result of pressure zoning?
A: The booster pump and most of the network will operate at a higher pressure
Q: What is a result of pressure zoning?
A: The main station and most of the network will operate at a much lower pressure
Q: What is a result of pressure zoning?
A: The main station and most of the network will operate at a higher pressure
Q: What must zones be equipped with in order to achieve a fixed constant pressure setpoint at the discharge?
A: A booster pump or pressure-reducing valve
Q: What must zones be equipped with in order to achieve a fixed constant pressure setpoint at the discharge?
A: An open valve or a pressure gauge
Q: What must zones be equipped with in order to achieve a fixed constant pressure setpoint at the discharge?
A: A flowmeter
Q: What is placed in critical pressure points of the distribution network to establish DDD?
A: A booster set
Q: What is placed in critical pressure points of the distribution network to establish DDD?
A: Pressure-reducing valves
Q: What is placed in critical pressure points of the distribution network to establish DDD?
A: Sensor data-loggers
Q: How can a water tower be retained without affecting the required network pressure?
A: Using a hydraulically operated control valve to fill and empty the water tower
Q: How can a water tower be retained without affecting the required network pressure?
A: By filling the water tower at night time when consumers are asleep
Q: How can a water tower be retained without affecting the required network pressure?
A: Using a small booster pump to supply water to the tank and a two-way hydraulically-operated control valve to remove water from the tank
