Backflow testing in Ajax
Ajax is on Regional water from the Lake Ontario plant in the town and sits under Durham Region By-law 24-2018 like every other municipality in the Region. There is no separate Ajax backflow program. Every ICI and multi-residential building on Regional water here has its device tested once a year and the report filed with the Region.
One program for all of Durham Region
The testing requirement in Ajax is set by Regional Municipality of Durham By-law 24-2018, the same by-law that covers every other Durham municipality. Notices come from BSI Online on the Region's behalf, reports are filed through the same portal, and the Region issues the tag. There is no separate Ajax program. See the Region's program page for the by-law and the tester registry.
Ajax’s building stock, from a backflow point of view
Ajax is a compact town with a clear pattern:
- Plazas. The town’s own planning documents describe downtown Ajax as dominated by single-storey plazas and parking lots. From a backflow point of view a plaza is a landlord’s premise device on the shared service plus tenant devices wherever there is a restaurant, a salon, a clinic or a dry cleaner. Notices for the premise device go to the landlord; tenant devices may be the tenant’s under the lease.
- Employment lands along Bayly Street and Salem Road South. Manufacturing, warehousing and services. Multiple devices per site: premise, boiler, wash bay. See the industrial page.
- Mid-rise residential and newer condos, including the developments around Pat Bayly Square. Buildings over six units are in the program. See apartments and condos.
- Medical and dental around the hospital and along Harwood and Kingston Road. RPZs, quiet-hours slots. See medical and dental.
- Institutional: schools, places of worship, community facilities.
The rule is Regional
By-law 24-2018 was passed by Durham Regional Council and is administered through BSI Online. Ajax does not run its own program. Notices for Ajax properties look exactly like notices for Pickering or Whitby properties, and the filing goes to the same place. The notice page explains the letter.
A note about search results: queries for “backflow testing Ajax” often surface a price from a Toronto company and a claim or two about municipal programs. The price is theirs, not Durham’s; the program is the Region’s, not the town’s.
Water context
Ajax is served by Regional water from the Lake Ontario water supply plant in the town, the westernmost of the Region’s lakeshore plants. All of Ajax’s urban area is on Regional supply and under the by-law.
Scheduling in Ajax
Ajax batches well. Typical morning: an apartment building at nine, a Bayly Street industrial premise device at eleven during a planned line-down, plaza devices after lunch. Restaurants and clinics along Harwood and Kingston Road get before-open or after-close slots. A property manager with Ajax and Pickering buildings gets one route.
| Building type | Usual slot |
|---|---|
| Plazas | Daytime, landlord and tenant devices together |
| Bayly and Salem industrial | Between shifts or a planned outage |
| Apartments and condos | Mid-morning or early afternoon, super notified |
| Restaurants and clinics | Before open or after close |
Plazas: the landlord and tenant question
Because plazas are such a large share of Ajax’s commercial stock, the landlord-tenant question comes up here more than anywhere. The by-law puts testing and repair costs on the owner (sections 6.3 and 6.4). For the plaza’s premise device, that is the landlord. For a device inside a unit that serves that tenant’s equipment, the lease usually passes the obligation to the tenant. When both are due, one visit covers both, and we invoice each party separately.
What it costs and what you get
Per device, per property, $25 BSI filing fee included, report submitted within the by-law’s 28-day window, tag, report copy for the five-year file, filing confirmation, and a reminder 30 days before next year. Details on the cost page.
Backflow testing in Ajax: questions
Is Pickering Village in Ajax or Pickering for backflow purposes?
Pickering Village is in the Town of Ajax. It does not matter for the by-law, which is Regional and identical in both municipalities, but it matters for who the area municipality is on the report. Either way, we test and file the same way.
We own a plaza on Harwood. Which devices are ours and which are the tenants'?
The premise isolation device on the plaza's water service is yours as the property owner and the notice for it comes to you. Devices inside tenant units serving their equipment (a restaurant carbonator, a salon) may be the tenant's under the lease. Send us the notice and we tell you which device it names; we test both on one visit and invoice separately if you like.
How does the AI answer that says Ajax testing is about $360 per device relate to your price?
That figure comes from a Toronto provider's published rate that a search engine surfaced for Ajax queries. It is a reference point, not a Durham rate. We quote per property based on device count, type, access and timing, with the $25 BSI filing fee included. See the cost page for what moves the number.
