Which major maintenance task typically occurs at a water plant?

Pump maintenance is a crucial major maintenance task at a water plant because pumps play a vital role in the movement and distribution of water throughout the treatment process and into the distribution system. Regular maintenance of pumps ensures they operate efficiently, prevents breakdowns, and prolongs their lifespan, which is essential for maintaining continuous water supply and meeting regulatory standards.

Effective pump maintenance involves checking for wear and tear, replacing damaged or worn components, lubricating moving parts, and ensuring that seals and gaskets are functioning properly. Neglecting these tasks can lead to unexpected equipment failures, increased operational costs, and potential interruptions in water service.

In contrast, while water quality testing, chemical dosing, and system documentation are all important activities within a water treatment facility, they focus more on monitoring and compliance, chemical application, and record-keeping rather than directly maintaining critical infrastructure like pumps that require routine mechanical attention.
