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 that keeps the system flowing, like cleaning pipes and manholes, isn’t a problem to solve—it's a standard upkeep task. The other items describe issues that staff must address: enforcing service connections helps prevent improper hookups and backflow problems; improper installations of sewer can lead to leaks and blockages; changing population patterns affect flow volumes and timings, creating capacity and design challenges. So, routine cleaning is the activity that doesn’t fit as a problem the operators deal with, while the others are actual challenges.
