What is the main objective of flushing a collections system?

Flushing a collections system is primarily aimed at clearing debris and sediments from pipes. Over time, solid materials, organic matter, and other deposits can accumulate within the sewer lines or collection system, which can impede the flow of wastewater and lead to blockages or backups. Regular flushing helps to maintain the system’s efficiency by removing these unwanted materials, ensuring that the flow remains unobstructed and the system operates effectively. This is crucial for preventing overflows and minimizing the risk of sanitary sewer overflows (SSOs), which can have environmental and public health implications.

Increasing water supply, enhancing the chemical treatment process, and replacing old infrastructure are not the main objectives of flushing. While maintaining a clear flow can indirectly support overall operational integrity and may relate to system maintenance strategies, the direct goal of flushing is specifically focused on debris and sediment removal.
