What is a sewer system?

A sewer system is specifically designed for the collection and transport of wastewater generated from residential, commercial, and industrial sources. This network ensures that wastewater is effectively moved away from these sources to treatment facilities, where it can be processed and purified before being released back into the environment or reused.

The importance of a sewer system lies in its role in maintaining public health and environmental safety. By transporting wastewater away from populated areas, the system helps prevent contamination of local water supplies and reduces the risk of disease outbreaks.

The other options describe different systems that serve distinct purposes. For instance, a system for distributing potable water pertains to the provision of safe drinking water to communities. Collecting stormwater runoff focuses on managing excess rainwater to prevent flooding and erosion. A facility for purifying drinking water specifically refers to treatment plants designed to clean water for safe consumption. Each of these systems plays a vital role in water management, but only a sewer system is focused on the collection and transport of wastewater.
