What is the term for water that enters any component of the pool system?

The term for water that enters any component of the pool system is influent. This refers to the flow of water into a specific area or system, such as the pool's filtration or circulation systems. Knowing this distinction is important for pool operators who must understand how water moves through various components to maintain proper circulation, filtration, and overall water quality.

Discharge typically refers to water being expelled from a system, effluent denotes water that has exited a treatment system and may refer to treated water being released, and bypass suggests a method to divert water around a component rather than through it. Each of these terms describes a different aspect of water flow in relation to the pool system. Understanding influent is crucial for effective pool management and ensuring that water enters the treatment processes as intended.
