To accommodate growth, the facility is undergoing a major expansion which will increase its capacity to serve 1.5 million people.</p><p>The project includes additional primary sedimentation tanks, solids contact tanks, and secondary clarifiers. A fast tracked portion of the project involved installing high speed turbo blowers in the plant’s live secondary treatment process, completed in April this year. </p><p>Geotechnical ground improvement work is currently underway, including installation of about 9,000 stone columns at an average of 30 metres deep. This also involves the relocation of existing major utilities, and is scheduled to be completed in mid-2016. </p><p>The overall project completion is expected in 2022, and the current estimated cost is $550 million. </p><p>The Annacis facility treats about 175 billion litres of wastewater each year. The treated water is then released into the Fraser River.
