The current facility is designed to treat waste for one million people.

The stage five project will expand the plant to handle an additional 250,000 people.

Metro Vancouver is about four years into the project and is currently working on the detail design for phase one, which is expected to be complete next fall.

Overall, the project is about 60 per cent complete on the design, Ferguson said.

Phase one target completion is 2018. The first phase includes expansion of primary tankage, secondary clarifiers, solid contact tanks and additional odour facilities.

...


Furthermore, Stage five expansion must be co-ordinated with other projects at the facility, including improvements to back up power and co-generation facility ($47 million) which generates 50 per cent of the plant's electricity; major clarifier maintenance ($20 million) and expansion of the Annacis outfall ($130 million).

All the Annacis projects total about $750 million.

The plant serves much of the Tri-Cities, Burnaby, Maple Ridge, Delta, Surrey, Pitt Meadows, Langley and White Rock. The last expansion was in 1998.
