Government of New Brunswick


The Department of Health is regulating cooling towers under the Public Health Act. Building owners are responsible for obtaining a licence to operate cooling tower systems associated with their buildings, which include an evaporative condenser and fluid cooler.

The Department of Justice and Public Safety is responsible for ensuring compliance with the Act and Regulation.

Proposed amendments to the Water Circulation Systems Regulation are now posted for public review and input. The new amendments include reference to the New Brunswick Technical Guidelines for Water Circulation Systems. A draft copy of the Guidelines can be found here. To provide comments on both the Regulation and Guidelines please visit Public Review of Draft Regulations.


A licence may be issued to a building owner who has completed an application for a licence and paid the required fee.
