Comprehensive cross-connection control surveys across Ontario. Identify hazards, assess risks, ensure compliance with municipal bylaws. OWWA certified specialists.
A backflow survey (also called a cross-connection control survey or backflow hazard assessment) is a comprehensive inspection of your property to identify potential cross-connections that could allow contaminated water to flow backward into the municipal water supply. Under Ontario municipal bylaws, many property owners are required to complete these surveys.
Our OWWA certified technicians systematically evaluate your property's plumbing systems, identifying hazards such as fire suppression systems, irrigation connections, commercial equipment, and other potential contamination sources. We then recommend appropriate backflow prevention measures and device requirements.
We review your property details, municipal requirements, and any existing backflow devices. We explain the survey process and what to expect.
Our certified technician conducts a thorough inspection of your property, examining all water connections, plumbing fixtures, and potential cross-connection hazards.
We identify and document all cross-connection hazards, classifying them by risk level (high, medium, or low hazard).
Based on our findings, we recommend appropriate backflow prevention devices (RPZ, DCVA, PVB) for each identified hazard.
We create a comprehensive survey report with findings, recommendations, and a compliance plan that meets municipal requirements.
We submit the survey report to your municipality and help coordinate any required device installations or modifications.
Our surveys identify hazards across all property types:
Sprinkler systems, standpipes, and fire pumps create high-hazard cross-connections requiring RPZ devices.
Lawn sprinklers, commercial irrigation, and agricultural systems can introduce fertilizers and chemicals.
Boilers, chillers, cooling towers, and process equipment in industrial facilities.
X-ray machines, sterilizers, and dental chairs in healthcare facilities.
Commercial kitchens, dishwashers, and food processing equipment.
Swimming pools, hot tubs, and water features with chemical treatment systems.
Survey costs depend on property size, complexity, and number of potential hazards:
$300 - $500
Single-story commercial buildings, small offices, retail shops
$500 - $800
Multi-story buildings, restaurants, medical facilities
$800 - $1,500+
Manufacturing facilities, large warehouses, complex systems
