Castaway Cove Water Park uses less water than a standard hotel and less than most car washes. The annual water consumption at the park is less than 3/100 of one percent of the city's total water use. Like a home pool, the water is recirculated and filtered. The pools are kept full during the winter months to reduce water use. As with any pool or body of water, evaporation occurs, especially during hot or windy days. To comply with City restrictions, the park has turned off various sprays to reduce water loss due to evaporation and irrigation (watering landscaping).
