Annacis Island Wastewater Treatment Plant- 1299 Derwent Way, Delta V3M 5V9
The Annacis Island Wastewater Treatment Plant (WWTP) is the  largest plant and provides secondary treatment to wastewater from approximately 1,000,000 people in parts of Burnaby, New Westminster, Port Moody,  Port Coquitlam, Coquitlam, Pitt Meadows, Maple Ridge, Surrey, Delta, White Rock, City of Langley and Township of Langley.
 
Biosolids produced in 2006 (dry tonnes/24-34% solids concentration): 12,000
Biosolids type: Class A
Solids digestion process: Anaerobic thermophilic (55°C)

Average wastewater flows from 1997 - 2006

Operational Certificate
Like all industrial users, the Annacis Island Wastewater Treatment Plant receives an operational certificate that restricts the volume and nature of the treated wastewater - also known as effluent - it can release into the environment. In 2006, this provincial government certificate allowed the plant to release:

2006 results  Biological Oxygen Demand (BOD)Total suspended solids (TSS)Maximum daily discharge
OC limits45 mg/L 45 mg/L 1,050 MLD (max.) 
Daily   average9 mg/L 12 mg/L  497 MLD
# of times   permit exceeded0 0 0 
1050 MLD = 1,050,000 m3/day 

Iona Island Wastewater Treatment Plant- 1000 Ferguson Road, Richmond V7B 1W7
The Iona Island Wastewater Treatment Plant provides primary treatment to wastewater from approximately 600,000 people (in Vancouver, the University Endowment Lands and parts of Burnaby and Richmond) before discharging it through a 7.5 km, deep-sea outfall into The Strait of Georgia.

The plant opened in 1963 and has been expanded six times for growth and treatment upgrades allowing more than 200 billion litres of wastewater to be treated here in 2001.
 
Biosolids produced in 2006 (dry tonnes/15% solids concentration): 5,000 (estimate)
Biosolids type: Class B
Solids digestion process: Anaerobic mesophilic (38°C)
Average wastewater flows from 1997 - 2006

Operational Certificate
Like all industrial users, the Iona Island Wastewater Treatment Plant receives an operational certificate that restricts the volume and nature of the treated wastewater - also known as effluent - it can release into the environment. In 2006, this provincial government certificate allowed the plant to release:

2006 results  Biological Oxygen Demand (BOD)Total suspended solids (TSS)Maximum daily discharge
OC limits130 mg/L 100 mg/L 1,530 MLD (max.) 
Daily   average92 mg/L 53 mg/L  587 MLD
# of times   permit exceeded1 0 0 
1530 MLD = 1,530,000 m3/day 

Lions Gate Wastewater Treatment Plant- 101 Bridge Road, West Vancouver V7P 3R2
The Lions Gate Wastewater Treatment Plant provides primary treatment to wastewater from approximately 174,000 residents of the District of West Vancouver, the City of North Vancouver, and the District of North Vancouver. The Lions Gate plant's treatment capacity is seven times as great as when it opened in 1961.
 
Biosolids produced in 2006 (dry tonnes/24-34% solids concentration): 670
Biosolids type: Class B
Solids digestion process: Anaerobic thermophilic (37-55°C)
Average wastewater flows from 1997 - 2006

Operational Certificate
Like all industrial users, the Lions Gate Wastewater Treatment Plant receives an operational certificate that restricts the volume and nature of the treated wastewater - also known as effluent - it can release into the environment. In 2006, this provincial government certificate allowed the plant to release:

2006 results  Biological Oxygen Demand (BOD)Total suspended solids (TSS)Maximum daily discharge
OC limits130 mg/L 130 mg/L 318 MLD (max.) 
Daily   average97 mg/L 97 mg/L  92.4 MLD
# of times   permit exceeded0 0 0 
318 MLD = 318,000 m3/day 

Northwest Langley Wastewater Treatment Plant- 10301 - 201 Street, Langley V1M 3G8
The Northwest Langley Wastewater Treatment Plant provides secondary treatment to wastewater from 18,981 residents of the Walnut Grove area in Langley.
 
Biosolids produced in 2006 (dry tonnes/15% solids concentration): 250 (estimate)
Biosolids type: Class B
Solids digestion process: Aerobic cryophilic (ambient)
Average wastewater flows from 1997 - 2006

Operational Certificate
Like all industrial users, the Northwest Langley Wastewater Treatment Plant receives an operational certificate that restricts the volume and nature of the treated wastewater - also known as effluent - it can release into the environment. In 2006, this provincial government certificate allowed the plant to release:

2006 results  Carboneous Biochemical oxygen demand (cBOD)Total suspended solids (TSS)Maximum daily discharge
OC limits45 mg/L 45 mg/L 42 MLD (max.) 
Daily   average<9 mg/L 14 mg/L  9.9 MLD
# of times   permit exceeded0 0 0 
42 MLD = 42,000 m3/day 

Lulu Island Wastewater Treatment Plant- 13500 Gilbert Road, Richmond V7E 2H8
The Lulu Island Wastewater Treatment Plant provides secondary treatment to wastewater from approximately 120,000 residents who live in the western area of the City of Richmond.

Opened in 1973, the plant's treatment capacity was increased by 50 per cent in 1988, and was upgraded from a primary treatment facility in 1999.
 
Biosolids produced in 2006 (dry tonnes/24-34% solids concentration): 1,850
Biosolids type: Class B
Solids digestion process: Anaerobic mesophilic (37°C)

 Lulu Island WWTP Expansion Project
Average wastewater flows from 1997 - 2006

Operational Certificate
