What is one of the main functions of a sewer system?

• A. To prevent local flooding
• B. To transport clean drinking water
• C. To facilitate stormwater drainage
• D. To collect and transport wastewater

Answer: (D)

One of the primary functions of a sewer system is to collect and transport wastewater. This includes the waste generated from homes, businesses, and industries, as well as stormwater in some systems. The collection process is crucial for maintaining public health, as it ensures that used water and contaminants are directed away from populated areas and treated in wastewater treatment facilities. This function helps to prevent environmental pollution and protects waterways from becoming contaminated. The other options, while related to water management, do not accurately describe a sewer system’s main role. For instance, preventing local flooding is typically a function of stormwater management systems rather than traditional sewer systems, which are designed specifically for wastewater. Similarly, transporting clean drinking water and facilitating stormwater drainage are generally the responsibilities of separate infrastructure systems (water supply systems and storm drains, respectively), not the sewer system itself.
