What are cooling towers or evaporation condensers

Cooling towers and evaporative condensers help to remove excess heat from large buildings, like power stations or chemical plants. If they are situated on non-domestic premises, you must notify the council in writing. 

The legislation is The Notification of Cooling Towers and Evaporative Condensers Regulations 1992.
