Final answer:
Of those listed, roofs, inner courts, vent shafts, light wells, or similar areas having rainwater rains shall discharge to drains.(option 2) Rainwater collected from roofs, inner courts, and similar areas should be directed into drains to manage water flow and prevent sewer overflow . This practice follows both historical and modern urban water management systems.
Step-by-step explanation:
The question pertains to where rainwater collected from roofs, inner courts, vent shafts, light wells, or similar areas should be discharged. The appropriate disposal of rainwater rains is essential in preventing water damage to buildings and in ensuring proper hydraulic flow in urban infrastructure to avoid flooding or overloading of sewer systems. According to the information provided, which draws from historical and modern engineering practices, rainwater should typically be directed into drains.
In more modern times, urban water management systems include elements designed to handle rainwater, such as combined sewer systems that can during dry weather handle all flows at a publicly owned treatment works (POTW), but may discharge untreated during large storms to prevent overflow.
Therefore, when designing urban landscapes or building structures, drainage systems are implemented to properly manage and control the discharge of rainwater.
Hence, the answer is option 2.
