Cooling Tower Registration

All existing cooling towers must be registered with San Antonio Water System. New cooling towers should be registered with SAWS prior to the start of operation.

A cooling tower is an open water recirculation device that uses fans or natural draft to draw or force air into contact and cool water through an evaporative process.

In large office buildings, up to half the water used could be for cooling tower use in this evaporative process. The most energy efficient systems utilize cooling towers for air conditioning. Because cooling towers use vast amounts of water, they must be managed accurately for efficient operation.

Would you like to save money on your water bill, on your chemical treatment costs and improve the performance of you cooling tower? SAWS is offering a free audit to help you answer these questions and identify methods for improvements.

Cooling Tower Operation Reminder

  • Cooling towers, not utilizing recycled water, shall operate a minimum of four (4) cycles of concentration.
  • Newly constructed cooling towers shall be operated with conductivity controllers, as well as make-up and blowdown meters.

Please complete the registration process for each cooling tower site.

Please note: All information is required.
