connection control or selection and installation of backflow prevention devices shall be

auxiliary water supply, a written confirmation by a qualified person stating that a physical
separation exists is an approved alternative to a backflow prevention device.

Report, the Director shall be allowed access, with reasonable notice, to any premises
that are connected to the water distribution system for the purpose of performing
inspections to locate possible cross connections. The Director may require a routine
cross connection inspection of the premises (at the owner's expense) to be performed
by a qualified person.

time as access is provided.

issue such notices to the person and take actions as the case may be, as may be
required to obtain compliance with these regulations, including shutting off the supply of
water to the premises until such time as compliance is obtained.

distribution system exists, a person on notice from the Director shall install premise
isolation within the building or complete property isolation in an ASSE 1060 certified
enclosure on the property line in addition to any other source of protection devices on
the premises.
5.2 Premise isolation shall be installed: (a) in buildings of moderate or severe hazard in
accordance with premise isolation requirements as stated in the Ontario Building Code

hazard ratings as in CSA B64.10, as follows: (a) Premises with a minor hazard
classification shall be isolated with a Dual Check Valve (DuC) backflow preventer. (b)
Premises with a moderate hazard classification shall be isolated with a Double Check
Valve Assembly (DCVA) backflow preventer. (c) Premises with a severe hazard
classification shall be isolated with a Reduced Pressure Principle (RP) backflow

contain additional or alternative requirements deemed necessary by the Town in
accordance with the provisions of this By-law.
6.2 If work is required, the owner receiving the 'Compliance Notice' shall retain a qualified
person(s) to undertake the stated works before the date stated in the 'Compliance
Notice' and advise the Town, in writing, of completion of the work within thirty(30) days
of the date stated.
6.3 If the owner to whom the Town has issued a Notice fails to comply with the 'Compliance
Notice', the Director, at their discretion, may:
(a) Instruct the owner to correct the fault at their expense within a specified time
period and if the Notice is not complied with, the Town may then shut off the water
service or services; and/or
(b) Request that the Chief Building Official consider issuing an unsafe order under
unsafe requirements in accordance with the Ontario Building Code Act, in a
condition that could be hazardous to the health or safety of persons in the normal
use of the building, persons outside the building or persons whose access to the
building has not been reasonably prevented; and/or
(c) Without notice to the owner, shut off water service, where the Town has
determined, in their sole discretion that an immediate threat of contamination to the
water system exists that may endanger public safety or health.
7. Maintenance and Field-Testing of Backflow Prevention Devices

prevention devices shall retain a qualified person, per Part 12, to annually inspect and
test, at the expense of the owner, and submit a Backflow Device Test Report on a form

All equipment used to test backflow preventers shall be verified or calibrated for
accuracy, as described in CAN/CSA B64.10.

or water services until the backflow prevention device has been tested and approved.

8.1 No person shall remove a backflow prevention device or part thereof after it has been
installed, and no owner of a building or structure in which a backflow prevention device
is installed shall cause or permit the removal of such device, unless such removal is:
(a) To facilitate the repair of the device and such device is replaced immediately
after such repair is carried out; or
(b) To replace the device with another device that meets or exceeds the provisions
of this By-law. In no instance shall the property, premise or building be without a
