Which item is NOT listed as a problem collection system operators deal with?

• A. Routine cleaning of pipes and manholes
• B. Enforcement of service connection
• C. Improper installations of sewer
• D. Changing patterns of population shifts

Answer: (A)

Routine maintenance activities such as cleaning pipes and manholes are standard operations, not problems that require problem-solving. Operators focus on issues like enforcing service connections to prevent improper hookups, and addressing improper installations that can cause blockages or infiltration/exfiltration. Changing patterns of population shifts affect flow and capacity planning, creating real challenges for the system. Because routine cleaning is a regular upkeep task rather than a problem to fix, it’s the item that isn’t listed as a problem operators deal with.
