What is the primary concern when dealing with sewer overflows?

The primary concern when dealing with sewer overflows is public health and environmental safety. Sewer overflows can lead to the release of untreated wastewater into the environment, which poses significant risks to human health by contaminating drinking water sources and increasing the risk of waterborne diseases. Additionally, these overflows can severely impact local ecosystems, harming aquatic life and disrupting natural habitats. Ensuring the safety of the public and protecting the environment are critical priorities when managing sewer systems and addressing overflow incidents, as the consequences can be far-reaching and serious.

The other considerations, such as costs of repairs, efficiency of the system, and the amount of waste processed, are important in the overall management of sewer systems but are secondary to the immediate health risks posed by sewer overflows.
