Permanent and semipermanent pools must have access to water supply and what feature?

• A. East access to water supply
• B. Sidewall drains
• C. Drainage channel
• D. None

Answer: (B)

The key idea here is that a pool needs both a way to fill and a reliable way to drain. The water supply handles filling and topping up the pool, while sidewall drains provide a direct, built-in path to remove water from the pool via the walls. This arrangement helps remove not just water but also debris and overflow, keeping the pool and its surroundings from pooling water and making maintenance easier. An east-facing access requirement isn’t relevant, and while a drainage channel can exist in some setups, sidewall drains are the standard, most effective method for draining a pool.
