Business Best Management Practices

Storm drain contamination is a particularly important issue in Port Coquitlam. The roadside and parking lot storm drains are separate from the sanitary sewer. Therefore, these storm drains discharge untreated into Port Coquitlam’s 30 km of open creeks and streams. These creeks form an important network of watercourses, which provide natural habitat for salmon, trout, and other aquatic life.

Best Management Practices

To prevent contaminants from entering the storm drain system and ultimately our creeks and rivers, we suggest that you implement the following best management practices.  Please refer to the links on the left hand side of this page for information that is specific to your business.

Storage and Disposal

Store cleaning and deodorizing chemicals, polishing compounds, solvents, acids and caustics in a secure area where spills will be contained and will not enter the drainage or the sanitary sewer systems.

Certain chemicals may require special disposal.  Follow the manufacturer’s directions for disposal of all products.  For further disposal information, contact the manufacturer, the BC Recycling Hotline at 604-732-9253 or the Ministry of Environment at 250-387-3205.

Ensure that flammable liquids do not enter drains, sewers or other plumbing fixtures.  Flammable liquids can create explosive conditions in our sewers.

Some waste fluids are considered “special wastes” under the Waste Management Act.  All special wastes require special handling, storage and disposal considerations.

Train employees on proper techniques and ensure all employees, maintenance companies and customers are aware of their important role in preventing storm drain contamination.


Spills must be contained and cleaned up immediately to prevent the material from entering the drainage or sanitary sewer systems.  Please follow the clean-up procedures as listed in the product’s Material Safety Data Sheet.

Some chemicals may be flammable, toxic, corrosive, or have other hazardous properties.  Call the Fire Department immediately at 911 or the Ministry of Environment, Provincial Emergency Program at 1-800-663-3456, if in doubt about any spill situation.


Section 11 of the City of Port Coquitlam Sewer Maintenance Bylaw, 1971, No. 1091 states that:
