Test results
01.
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
01.
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
01.
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
02.

03.
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
03.
Q: What must zones be equipped with in order to achieve a fixed constant pressure setpoint at the discharge?

03.
Q: What must zones be equipped with in order to achieve a fixed constant pressure setpoint at the discharge?
A: A flowmeter
04.
Q: What is the general purpose of a water tower?
A: To keep the water in the distribution pipe network pressurised
04.
Q: What is the general purpose of a water tower?
A: To boost pressure in the distribution area
04.
Q: What is the general purpose of a water tower?
A: To keep a volume of water for emergency use
05.
Q: What is a result of pressure zoning?
A: The booster pump and most of the network will operate at a higher pressure
05.
Q: What is a result of pressure zoning?
A: The main station and most of the network will operate at a much lower pressure
05.
Q: What is a result of pressure zoning?
A: The main station and most of the network will operate at a higher pressure
06.
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
06.
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
06.
Q: What happens with the control valve if network pressure gets too low?
A: The control valve does not respond to network pressure
07.
Q: What does DMAs make it easier to localise?
A: High Pressure
07.
Q: What does DMAs make it easier to localise?
A: Leaks
07.
