Liquid Waste Discharge Limits
The Greater Vancouver Regional District (GVRD) Sewer Use Bylaw No. 164,
regulates pollutants that are discharged into sewers and drains. Protection of the
environment and human health and safety are the first priorities of this bylaw.
Although some contaminants are reduced during the primary treatment process at
the sewage treatment plant, others pass through untouched and end up in the
“By controlling the level of pollutants discharged into sewers and drains, the District can protect both the environment and its collection and treatment systems.”
Specific types of waste are either prohibited, outright, or restricted to an allowable
concentration. “Prohibited Wastes” are wastes that can damage the sewer system and sewerage facilities or pose a threat to worker health and safety. The District emphasizes the treatment of waste, to the greatest degree possible, prior to discharge to sewer.
