What is a primary concern when dealing with inflow and infiltration in sewer systems?

The primary concern when addressing inflow and infiltration in sewer systems is the maintenance of the structural integrity of pipelines. Inflow refers to stormwater that enters the sewer system from external sources during heavy rain, while infiltration refers to groundwater that seeps into the sewer system through cracks or defects in the pipelines.

When these additional volumes of water enter the system, they can overwhelm treatment facilities, leading to increased pressure on the infrastructure. This can result in severe consequences such as pipeline failures, cracks, leaks, and ultimately, structural collapse. Ensuring the integrity of the pipelines is essential to prevent these issues, maintaining both the safety of the wastewater system and the surrounding environment.

Addressing inflow and infiltration is crucial to maintaining the performance and longevity of sewer systems, as well as ensuring the efficient flow of wastewater to treatment facilities. This focus on structural integrity mitigates the risk of costly repairs and disruptions in service, ultimately contributing to a more effective wastewater management strategy.
