Cross-Connection Survey

Cross-Connection Survey cover

Did you receive a Cross-Connection Survey Letter?


The government of Ontario has stated that the Cross-Connection Survey is mandatory for all the commercial, industrial and municipal facilities across the GTA. Atre Drain and Plumbing is authorized by the Municipalities of the Peel Region, Toronto, Halton, Markham and other regions in Ontario to submit a Cross-Connection Survey on behalf of our customers. We help your company located in Toronto, Vaughn, Markham, Mississauga, Brampton, Oakville, Burlington, Milton or Hamilton. We have all the necessary certificates, tools and experience to complete your Cross-Connection Survey without causing interruptions to your business.


What is a Cross-Connection Survey? Let us see.


The cross-connection survey is an investigation of the drinking water system with a purpose of determining the presence or absence of any existing or potential drinking water contamination, known as backflow. Upon the survey completion, an industry professional from City’s Cross-Control Program Department will recommend a backflow prevention device for further installation. This guarantees your property will help maintain the security of the Municipal drinking water.

Where should you begin? Let us help.

Atre Drain & Plumbing is a qualified business that will gladly assist you on every step of the Cross-Connection Survey. Furthermore, we will prepare and then submit your Cross-Connection Survey electronically in order to save your time and will actively communicate with the municipal organization on every step of the application process. Subsequently, the city will forward you a request letter with the assigned equipment which you will have to implement and we will install all the necessary backflow prevention devices.
