1. What is the primary goal of water loss control in a distribution
system?
a) Reduce water treatment costs
b) Maintain water quality
c) Minimize non-revenue water and system leakage
d) Increase water pressure
Minimizing non-revenue water and system leakage ensures that
utilities efficiently manage water resources and revenue.
2. Which of the following is considered apparent water loss?
a) Leaks in pipelines
b) Meter inaccuracies and unauthorized consumption
c) Main breaks
d) Pipe bursts
Apparent losses occur due to measurement or billing errors
rather than physical leaks.
3. What does the term “real water loss” refer to?
a) Inaccurate meters
, b) Physical losses from leaks, bursts, or overflows
c) Billing errors
d) Customer theft
Real losses are physical losses of water from the distribution
system.
4. What is the first step in developing a water loss control program?
a) Install smart meters
b) Conduct a water audit
c) Repair all leaks immediately
d) Reduce water pressure
A water audit quantifies water use and losses, forming the basis
for control measures.
5. Which AWWA standard provides guidance on water audits?
a) M36
b) M36
c) C651
d) G100
AWWA M36 is the official manual for water audits and loss
control for public water systems.
6. What does NRW stand for in water management?
a) Normalized Reservoir Water
b) Non-Revenue Water
c) Natural Resource Waste
d) Network Recharge Water
Non-Revenue Water represents water that is produced but not
billed due to losses.
7. Which method is commonly used to locate leaks in a distribution
system?
a) Hydraulic modeling
, b) Acoustic leak detection
c) Water quality sampling
d) Chlorine residual testing
Acoustic leak detection uses sound to identify pressurized leaks
underground.
8. How can pressure management reduce water loss?
a) By increasing flow
b) By lowering excessive system pressure
c) By installing more meters
d) By increasing chemical dosing
Reducing pressure reduces the rate and frequency of leaks,
prolonging pipe life.
9. Which of the following is a key indicator of water loss efficiency?
a) Average daily flow
b) Water loss per service connection or per km of pipe
c) Customer complaints
d) Meter calibration frequency
Measuring water loss relative to system size helps assess the
effectiveness of loss control programs.
10. Which factor contributes most to real losses in old water
distribution systems?
a) Meter inaccuracies
b) Aging pipes and joints
c) Customer theft
d) Billing errors
Older infrastructure is more prone to leaks, bursts, and breaks.
11. What is the difference between intermittent and continuous
leaks?
a) Intermittent leaks occur only at night
