Q: What is the most efficient way to operate a water distribution system?
A: Using a proportional pressure control system
01.
Q: What is the most efficient way to operate a water distribution system?
A: Using a fixed constant pressure setpoint
01.
Q: What is the most efficient way to operate a water distribution system?
A: Using a pressure reducing valve
02.
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
02.
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
02.
Q: What happens with the control valve if network pressure gets too low?
A: The control valve does not respond to network pressure
03.
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
03.
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
03.

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
05.
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
05.
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
06.
Q: What is the general purpose of a water tower?
A: To keep the water in the distribution pipe network pressurised
06.
Q: What is the general purpose of a water tower?
A: To boost pressure in the distribution area
06.
Q: What is the general purpose of a water tower?
A: To keep a volume of water for emergency use
07.

A: A booster pump or pressure-reducing valve
07.
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
07.
Q: What must zones be equipped with in order to achieve a fixed constant pressure setpoint at the discharge?
A: A flowmeter
