- Water evaporation increases when it's windy. Wind speed controls help reduce loss of water from evaporation in high wind conditions, splashing and uncontrolled spray.
- Reducing water loss is especially important during dry conditions or in drier areas of the country, like the Southwest. The design of large water fountains that use less water typically include the installation of wind speed controls, combined with factors like the height of the spray and the size of the catch basin.
- Water fountains have great aesthetic appeal. They also cool the air, reduce surrounding noise, conserve water. Many city governments such as the City of Phoenix regulate fountains and recommend the installation of wind speed controls.
