Which term describes unusually strong wastewater discharge from a waste source?

Explanation:
A shock load is a sudden, unusually strong discharge of wastewater from a source, causing a rapid spike in the amount or strength of pollutants entering the treatment system. This term captures the idea of an unexpected surge, such as from industrial dumping or a rain-induced surge, that can challenge treatment processes. BOD measures how much oxygen would be consumed to break down the organic matter in water, indicating pollution strength but not describing a spike in discharge. Infiltration/Inflow refers to extra water entering the sewer system (often from rain or leaks), increasing volume rather than signaling a strong discharge from a specific source. Anaerobic decomposition is the process of decay without oxygen, not a descriptor of discharge events.
