What is the primary purpose of a sewer system?

• A. To provide drinking water
• B. To transport wastewater away from populated areas
• C. To store rainwater
• D. To treat solid waste

Answer: (B)

The primary purpose of a sewer system is to transport wastewater away from populated areas. This includes all forms of wastewater produced in residential, commercial, and industrial settings, such as sewage and greywater. Properly functioning sewer systems are essential for maintaining public health and environmental safety by ensuring that wastewater is moved efficiently to treatment facilities and away from areas where people live and work. This helps to prevent pollution, reduce the risk of diseases associated with improper waste disposal, and maintain the cleanliness of urban environments. In contrast, the other options pertain to different aspects of water management. Providing drinking water involves a separate infrastructure that includes water treatment and distribution systems. Storing rainwater typically falls under stormwater management and is not the function of sewer systems. Finally, treating solid waste is another specialized process that usually takes place at waste management facilities rather than within the sewer system itself, which focuses on liquid waste.
