Correct
Q: What is a result of pressure zoning?
A: The main station and most of the network will operate at a much lower pressure
Correct
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
Correct
Q: What is placed in critical pressure points of the distribution network to establish DDD?
A: Sensor data-loggers
Correct
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
Correct
Q: What does DMA stand for?
A: District Metering Area
Correct
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
Correct
Q: What is the most efficient way to operate a water distribution system?
A: Using a proportional pressure control system
Correct
Q: What does DMAs make it easier to localise?
A: Leaks
