INTRODUCTION *
The Tennessee Municipal Water Systems Engineer Exam evaluates the technical knowledge,
engineering judgment, and professional competencies required to plan, design, operate,
maintain, and improve municipal water systems. Candidates are assessed on water
treatment principles, hydraulic design, distribution networks, regulatory requirements, public
,health protection, and infrastructure management. The examination includes multiple-
choice and scenario-based questions that measure both theoretical understanding and
practical application. Emphasis is placed on sound decision-making, compliance with
applicable standards, effective problem-solving, and the ability to address real-world
challenges encountered in municipal water utility engineering environments.
SECTION ONE (QUESTIONS 1–50)
Question 1
What is the primary purpose of a municipal water distribution system?
A. To generate electrical power
B. To transport potable water to consumers
C. To treat wastewater before discharge
D. To recharge groundwater aquifers
🟢 Correct Answer: B. To transport potable water to consumers
🔴 Explanation: The distribution system delivers treated drinking water from treatment
facilities to customers safely and reliably.
Question 2
Which unit is commonly used to measure water flow rate in municipal systems?
,A. Gallons per minute (GPM)
B. Pounds per square inch (PSI)
C. Kilowatt-hours (kWh)
D. Degrees Fahrenheit (°F)
🟢 Correct Answer: A. Gallons per minute (GPM)
🔴 Explanation: Flow rate is commonly measured in GPM, MGD, or cubic feet per second.
Question 3
A water treatment plant adds chlorine primarily to:
A. Increase hardness
B. Improve taste
C. Disinfect pathogens
D. Reduce pressure
🟢 Correct Answer: C. Disinfect pathogens
🔴 Explanation: Chlorination destroys harmful microorganisms and protects public health.
, Question 4
Which component is used to isolate sections of a water distribution system?
A. Fire hydrant
B. Check valve
C. Air release valve
D. Gate valve
🟢 Correct Answer: D. Gate valve
🔴 Explanation: Gate valves allow operators to isolate portions of the system for
maintenance or emergencies.
Question 5
What is the primary function of a water storage tank?
A. Wastewater treatment
B. Pressure reduction only
C. Flow metering
D. Equalizing demand and maintaining pressure
🟢 Correct Answer: D. Equalizing demand and maintaining pressure
