Achieved badges:
How would you rate this course?
1: What happens with the control valve if network pressure gets too low?
The control valve will open to maintain the minimum network pressure
1: What happens with the control valve if network pressure gets too low?
The control valve will close, stopping water from entering the network

1: What happens with the control valve if network pressure gets too low?
The control valve does not respond to network pressure

2: What is the general purpose of a water tower?
To keep the water in the distribution pipe network pressurised
2: What is the general purpose of a water tower?
To boost pressure in the distribution area

2: What is the general purpose of a water tower?
To keep a volume of water for emergency use
You can find the answer here >
3: How can a water tower be retained without affecting the required network pressure?
Using a hydraulically operated control valve to fill and empty the water tower
You can find the answer here >
3: How can a water tower be retained without affecting the required network pressure?
By filling the water tower at night time when consumers are asleep

3: How can a water tower be retained without affecting the required network pressure?
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
4: What is a result of pressure zoning?
The booster pump and most of the network will operate at a higher pressure
You can find the answer here >
4: What is a result of pressure zoning?
The main station and most of the network will operate at a much lower pressure

6: How much of the data available to a water utility is actively used?
An estimated 1%
6: How much of the data available to a water utility is actively used?
Very few water utilities can draw on data

7: How is a DMA created?
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
7: How is a DMA created?
By leaving open a few valves within the distribution pipe network and installing consumer meters to register water supplied to the DMA
