A cooling tower reduces the temperature in the air. It works by exposing water to fan-forced air. This process releases a mist of water into the air. 

Cooling towers can be on:

  • Commercial buildings
  • Industrial buildings
  • Residential buildings

They are different from water tanks, which store water for:

  • Drinking
  • Washing dishes
  • Showering

Buildings must register their cooling towers and cooling tower systems. Buildings that fail to register their towers may be subject to a fine.

Each year, building owners must certify they are following cooling tower regulations. The deadline is November 1.
