1. Under the Surface Water Treatment Rule a multiple barrier treatment consists
of
Removal by filtration and inactivation by disinfection
Coagulation, Flocculation, Sedimentation
CT Value, Residual, Filter
Bar Screens, Filters, Ozone
2. Why is it important for operators to maintain a detailed inventory of the
distribution system and each site during valve maintenance?
It provides a historical record of water usage.
It helps in budgeting for new equipment purchases.
It ensures that all valves are accounted for and properly maintained,
which is crucial for system reliability.
It allows operators to reduce the number of staff needed.
3. If a tapping saddle is incorrectly installed at a 90-degree angle, what
potential issues could arise in the water distribution system?
No impact on the water distribution system.
Enhanced disinfection of the water supply.
Increased stress on the pipe leading to leaks.
Improved water flow efficiency.
,4. If a water treatment plant experiences a sudden increase in flow rate due to
heavy rainfall, what system should be in place to maintain water quality?
Automatic proportioning of disinfectant dosage
Use of alternative water sources
Increased manual monitoring of water quality
Temporary shutdown of the plant
5. TCEQ's rules or functions include:
Setting water quality standards
Administrating discharge monitoring and issue permits
Enforce the Clean Water Act (CWA)
Certify and license operators
All of the above
6. In a scenario where a water distribution system needs to be shut down for
maintenance, which type of valve would be most appropriate to use for
isolating sections of the pipeline?
Pressure relief valves
Gate valves
Backflow prevention valves
Flow control valves
7. Customer services are most commonly metered with what type of meters?
miniturbine
nutating disc
, positive displacement
remote reading
8. What is a major deviation related to valves in water distribution systems?
Water quality
Pressure maintenance
Disinfection processes
Operational standards
9. What is used to locate a chlorine gas leak?
Hydrogen peroxide
Distilled water
Ammonia solution
Sulfur
10. What is the minimum frequency for inspecting excavations according to
Texas Class C water license regulations?
Weekly
Daily
Monthly
Yearly
11. What is the sequence of processes used in conventional surface drinking
water treatment plants?
softening, disinfection, sedimentation, flocculation
, coagulation, flocculation, sedimentation, filtration, disinfection
filtration, disinfection, flocculation, sedimentation
coagulation, flocculation, disinfection, sedimentation
12. Describe the significance of major improvements in the context of water
distribution systems as defined by TCEQ.
Major improvements are essential for ensuring the safety and
efficiency of water distribution systems.
Major improvements are unrelated to water quality.
Major improvements only refer to aesthetic changes in water facilities.
Major improvements are solely focused on financial aspects of water
utilities.
13. If a centrifugal pump is not providing adequate water pressure, what could
be a potential issue related to the impeller's function?
Increased water viscosity
Improper disinfection processes
Excessive water temperature
Insufficient kinetic energy generation
14. If a water utility operator identifies a need for major improvements in their
distribution system, what steps should they take according to TCEQ
guidelines?
They should ignore the issues until they become critical.
They should assess the current system, plan the improvements, and
ensure compliance with TCEQ regulations.
They should only focus on minor repairs and maintenance.
