Water Distribution Grade 1 Certification Practice Exam

What is typically included in a water distribution system maintenance schedule?

1. Cleaning tanks and disinfecting pipelines

2. Installing new meters

3. Checking for overgrown vegetation

4. Monitoring water taste

The correct answer is: Cleaning tanks and disinfecting pipelines

A comprehensive water distribution system maintenance schedule is essential for ensuring the quality and safety of drinking water. Cleaning tanks and disinfecting pipelines is a critical component of this schedule because it helps to remove sediment, biofilm, and potential pathogens that can compromise water quality. Regular disinfection also prevents the growth of harmful microorganisms that could pose health risks to consumers. This maintenance practice ensures that the system operates effectively and that the water delivered to users is safe for consumption. Additionally, keeping tanks clean and pipelines disinfected helps to reduce system breakdowns and prolongs the life of the infrastructure. While installing new meters, checking for overgrown vegetation, and monitoring water taste may be important activities in their own right, they do not directly address the fundamental requirements for maintaining water quality and system integrity in the same way that cleaning and disinfection do.
