    • base plumbing permit fees from $40 to $100;
    • installation or alteration (if not more than two fixtures or devices are to be erected or installed) from $20 to $50; and
    • permanent connection of an existing plumbing system to a communal waterworks from $20 to $50.
  • Provisions that enable the local authority to require the owner of an existing plumbing system to correct faulty or defective portions of the plumbing system.

Please note: The Private Sewage Works Amendment Regulations have not come into effect.

PHI Role:

Public health inspectors inspect and permit plumbing systems to ensure proper construction and reduce or eliminate health hazards such as sewage gas, cross connections and sewage back-ups. The legislation used by public health inspectors in Saskatchewan to regulate plumbing are The Plumbing Regulations, 2017 and the 2015 National Plumbing Code of Canada. Public health inspectors also participate in home owner education, plan consultation and complaint inspections.

Permit Requirements:

Plumbing systems that are constructed in the three northern health regions all require a plumbing permit. Without a permit one cannot connect a plumbing system to a communal or municipal water works. Most permits are issued during the inspection by the Public Health Inspector (with the exception of urban plumbing permits in La Ronge and Creighton municipalities).

To be eligible to take out a plumbing permit the following apply:

  1. If you are connecting to municipal/communal waterworks or sewage works the work must be completed by a journeyman plumber.
  2. If you are connecting to private sewage works the work does not have to be completed by a journeyman plumber; however, the work still has to comply with the 2015 National Plumbing Code of Canada.

Permits are not required when changing fixtures but are required for any new construction or when changing any vent or drain piping.

You must give your local public health inspector at least 72 hours notice to arrange an inspection. If you do not meet this time requirement there is no guarantee the public health inspector will be able to inspect when you request.

An inspection is required before any of the plumbing has been covered and a permit will only be completed if all the work is left visible for inspection (and if there are no code violations).

For larger plumbing jobs, such as those done on commercial buildings or multiunit dwellings, a building plan and plumbing plan must be submitted in advance and before the work has started.  This gives the Public Health Inspector a chance to review the plumbing plan before the inspection is conducted. This will increase inspection efficiency and allow the contracting timeline to stay on track.

Local Authority Requirements:

Since September 16, 2014, the three northern health regions have required the following of all plumbing installations; contractors and plumbers operating in the north were notified by mail:

  1. Air admittance valves are not permitted in new or renovated installations - no longer in enforced.
  2. Backflow prevention is required on all residential and commercial installations.
  3. Backwater valves are required on building drains on all below street level installations. Closed valve designs may be permitted if vented between the backwater valve and the outside wall (nearest the building sewer).
  4. Drainage systems located in outside walls are not permitted.
  5. Permits must be obtained PRIOR to installations. Permits will not be issued for installations that have been completed without proper inspection.

 NEW (September 2018):

As per guidance from the Ministry a 1:10 inspection ratio may be applied at the Health Region's discretion for plumbers who consistently follow the 2015 National Plumbing Code.  What does this mean?

  • Plumber must still fill out the permit application and apply ahead of time
  • If it is decided that the 1:10 inspection ratio applies an onsite inspection of the work will not be conducted (only 1 out of every 10 jobs will be inspected).
    • It is still expected that the plumber submit pictures of the air or water test, as well as an isometric drawing.  Plumbing pictures will only be accepted if they are properly labelled. 
  • This applies to residential plumbing only - commercial applications and large multi dwelling units will still be inspected.
