A cooling tower reduces temperature by exposing recirculated water directly to fan-forced air. This process releases a mist of evaporated, recirculated water into the atmosphere.
Cooling towers can be on commercial, industrial, or residential buildings. They are different than water tanks, which store water for drinking, washing dishes, and showering.
Buildings with cooling towers or cooling tower systems must be registered on the NYC Department of Health's website. Buildings that fail to register their towers may be subject to a fine.
Building owners must annually certify that their cooling towers were cleaned according to regulations.
Register or certify your cooling tower, or get more information and guidance.
