Each treatment plant is issued an Operational Certificate by the BC Ministry of Environment. The Operational Certificate requires effluent released from the treatment plant to meet certain treatment standards.
Monthly reporting of effluent quality data is provided for each wastewater treatment plant:
A small amount of liquid waste is brought to wastewater treatment plants by truck, instead of through the regional sewer system. A summary of trucked liquid waste disposed of at the Iona Island, Annacis Island and Northwest Langley wastewater treatment plants is also provided monthly.
