What is the maximum depth for standing water after the cessation of water addition to the deck of a pool?

The maximum depth for standing water after the cessation of water addition to the deck of a pool is set at 1/8 inch. This standard is designed to prevent water from pooling excessively on the deck, which can lead to safety hazards such as slips and falls. Additionally, excess standing water can facilitate the growth of algae and bacteria, creating health risks.

Maintaining a slight slope on the pool deck towards the drain helps ensure that any water that does collect will flow away efficiently, thus minimizing the risk of standing water. The 1/8 inch threshold is a practical limit that balances usability and safety, ensuring that any residual water does not create problematic conditions while allowing for minor residue that may occur after cleaning or rains. This standard reflects best practices in pool maintenance and safety guidelines.
