Sorry. You did not pass the Water Distribution test this time

Correct
Q: What is the Grundfos intelligent pumping system solution called?
A: Demand Driven Distribution
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 placed in critical pressure points of the distribution network to establish DDD?
A: Sensor data-loggers
Correct
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
Correct
Q: What is the most efficient way to operate a water distribution system?
A: Using a proportional pressure control system
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: What does DMAs make it easier to localise?
A: Leaks
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
