Which type of pipes are primarily associated with sanitary sewer systems?

The correct choice is associated with the primary purpose of sanitary sewer systems, which are specifically designed to transport wastewater generated from both domestic sources, such as homes and businesses, as well as industrial wastewater. This includes sewage and other liquid waste, ensuring that it is directed to wastewater treatment plants for proper processing and treatment before being released back into the environment.

The other options focus on specific types of pipes that do not align with the function of sanitary sewer systems. For instance, pipes that carry only stormwater are specifically designed to handle runoff from precipitation and do not deal with sewage, while pipes for transporting industrial waste are meant for specific applications of industrial processes and may not encompass domestic wastewater management. Similarly, pipes used for stormwater storage are not involved in the transportation of sanitary waste and focus instead on managing excess water from rainfall or other storm events.
