Public Drinking Water Branch

Permits and Engineering

If your place of business provides drinking water or if you're planning new or improved drinking water service for your customers, you may need a construction authorization permit from the department’s Public Drinking Water Branch.

Public water suppliers are also required to obtain an operating permit before putting newly constructed equipment, facilities or mains into operation. Permit section personnel review permit applications to ensure adequate water is available, the system is properly designed, and to verify that the system or equipment complies with all applicable standards and regulations prior to the issuance of the permit.

Working with the department to obtain the correct permit will help you stay in compliance with environmental regulations.
