Commercial Plumbing in Courtice, Ontario

Plumbing for Courtice Main Street Businesses

Courtice Main Street is the stretch of Highway 2 that Clarington's secondary plan describes as running about four kilometres from Townline Road in the west to Courtice Road in the east. The plan describes the western end as conventional strip plazas and gas stations, and the central blocks as small retail, office and service businesses anchored by small-scale plazas.

Over the long term, the plan expects these blocks to redevelop as mixed-use buildings with shops at street level and apartments above, with a Regional Centre identified where Trulls Road meets Highway 2. Buildings like that put commercial units and homes on one water and drain system, so shut-off valves, risers and backflow protection need to be planned and maintained with both in mind.

Backflow Prevention Rules for Courtice Properties

Courtice's urban area is on Region of Durham water, and the Region's backflow rules (By-law 24-2018) cover businesses, institutions, industrial sites and larger apartment buildings whose water connections fall in the moderate or severe hazard classes of the CSA B64 standards. The device depends on the hazard: a severe hazard calls for a reduced pressure principle assembly (RP), and a moderate hazard for a double check valve assembly (DCVA), usually installed just past the Region's water meter.

The process starts with a notice from the Region. Within 90 days, a qualified contractor must complete a cross connection survey and submit it online to Backflow Solutions Inc., the company the Region uses to run the program. If the survey shows a device is needed, or an existing one needs repair or testing, the owner has 180 days from the Region's follow-up notice to get it done. After that, every device is tested each year, and the survey is redone every five years and again whenever the tenant, owner, zoning, process or chemical use changes, which matters in multi-tenant plazas.

The Region requires testers to be certified by the Ontario Water Works Association, or another body it approves, and to register with the program. Hayes installs, repairs and tests backflow preventers with certified testers and gives you the paperwork for your files.

Grease and Oil Interceptors Under the Sewer Use By-law

Kitchens and garages have their own obligations under the Region's sewer use rules (By-law 55-2013). A Courtice restaurant, or any other business that cooks or prepares food and drains to a sanitary sewer, needs an interceptor for oil and grease installed to the CSA B481 standards, and must keep proof of each clean-out for a year.

Part V of the same by-law covers vehicle work. A service station, repair shop or garage where vehicles are repaired, lubricated or maintained, and whose drains connect to a sewer, must have an interceptor that keeps motor oil and lubricating grease out of the sewer. The by-law requires it to be inspected at least once a week, and the owner must be able to show the Region's by-law officer a maintenance schedule and the maintenance records on request.

If you are fitting out a Courtice unit for food service or vehicle work, build the interceptor into the plumbing design from the start, and ask the Region of Durham, through 311, what applies to your unit.

Permits, Inspections and Wastewater in Courtice

Courtice is part of Clarington, so even though Oshawa is next door, Clarington is the one that issues plumbing permits for a Courtice building, with applications made online on the Service Clarington site. Clarington's general guidance is that altering or adding plumbing normally needs a permit and swapping out fixtures normally does not. That list is written mainly with houses in mind, so confirm what a commercial unit needs with Clarington's Building Division (905-623-3379, extension 2660).

On commercial and multi-residential jobs, Clarington inspects plumbing in stages: outside services, including the sanitary and storm sewers and the domestic and fire line piping; inside services below the floor; the rough-in of drains, vents and water distribution; and a final plumbing occupancy inspection. A Clarington plumbing inspector must witness the tests, and inspection requests to 905-623-7876 have to arrive by 3 p.m. one business day ahead.

Wastewater from Courtice and Oshawa flows to the Region's Harmony Creek pumping station. According to the Region's 2025 performance report, about three quarters of it is treated at the Courtice Water Pollution Control Plant and the rest at the Harmony Creek plant in Oshawa. The Region, not Clarington, runs the water supply and the sanitary sewers, so call the Region about a watermain or sewer main problem in the road, and call us about the pipes in your building.
