What type of damages may industrial wastes cause to a POTW agency's collection system?

When industrial wastes are introduced into a Publicly Owned Treatment Works (POTW) agency's collection system, they can lead to various severe issues, particularly clogging, corrosion, and even explosions.

Clogging occurs when industrial wastes contain materials that do not break down easily in the wastewater treatment process. These materials can accumulate over time in pipes, leading to blockages that disrupt the flow of wastewater and can result in overflows and backups.

Corrosion is another critical issue, as many industrial wastes can be highly acidic or contain harmful chemicals that deteriorate the materials used in the collection system's infrastructure. This degradation can weaken pipes, joints, and other components, ultimately leading to structural failures and costly repairs.

Explosions, although less common, can occur when certain industrial pollutants interact inappropriately within the collection system. For instance, the buildup of gases from decomposing organic materials or specific chemicals can create flammable conditions that pose significant safety risks.

These impacts underscore the importance of managing industrial discharges and adhering to regulations that protect the structural integrity and functionality of the POTW's collection system.
