Whether your swimming pool water is safe to drink or not may not make much of a difference. Unless your pool has a bottom skimmer or another method to intake water for filtration from the bottom of the pool, you will only be able to use a limited amount of the water. Once the water level drops below the level of the filter intakes, the pool water will go bad pretty quickly.
