Backflow Preventer Wastewater Capture Tank

The project involves the construction/installation of a campus backflow preventer, including a  200 000 L fiberglass wastewater capture tank at the CFIA Ottawa Fallowfield Laboratory located at 3851 Fallowfield Road, Ottawa, Ontario. The project includes the construction of a new 4.5m x 6.2m building to house the installation of a backflow preventer, piping and electrical infrastructure, and an underground waste water capture tank.  The purpose of the tank is to capture wastewater in situations where a backflow preventer failure occurs. In the event that the backflow preventer is activated, the gravity-fed tank will fill and will be pumped out by a licensed hauler and disposed off-site at an approved facility after the event. The types of activity for this project include civil work, welding, piping, mechanical, electrical, excavation, and general soil & materials handling.

Latest update

The Canadian Food Inspection Agency (CFIA) has determined that the proposed backflow preventer wastewater capture tank at CFIA’s Ottawa-Fallowfield Laboratory is not likely to cause significant adverse environmental effects.  Potential environmental effects will be managed through technically and economically feasible mitigation measures and implemented for the following: air, water, soil, migratory birds, and species at risk, wildlife, and vegetation. Therefore, the Canadian Food Inspection Agency may carry out the project, exercise any power, perform any duty or function, or provide financial assistance to enable the project to be carried out in whole or in part.
