Our irrigation design

Backflow is defined as the reversal of flow, from the intended direction in a potable water system. Backflow hazards occur through temporary or permanent cross connections made between a potable drinking water system and any source containing non-potable water or other substances. There are two main means in which backflow occurs, backsiphonage and backpressure.

A backflow prevention device is a device or assembly that prevents backflow. Premises with a moderate hazard classification will require a Double check valve assembly (DCVA). Premises with a severe hazard classification will require a reduced pressure backflow assembly (RP).

Residential premises are classified under the standard CSA B64.10-111 as a minor hazard, and currently, do not require a backflow prevention device. However, residential premises with access to an auxiliary water supply, Irrigation systems, and solar hot water systems will require a premise isolation backflow prevention device.

Multi-residential premises, defined as 4 or more self-contained units on one premise, will be required to have a premise isolation backflow prevention device.
