Air Management Facility - Under Alex Fraser Bridge

<div class="ExternalClassACF9A80320A745FD8541F46FF568B3B5"><p>The South Surrey Interceptor is a large sewer pipe that moves approximately 500 million litres of wastewater daily from municipalities in the eastern part of the region to the Annacis Island Wastewater Treatment Plant in Delta.</p><p>In recent years, there have been odour issues related to the South Surrey Interceptor. As the population continues to grow and neighbourhoods become denser, Metro Vancouver is taking steps to address odour by constructing a series of air management facilities.</p><p>As part of the effort to address the odour issue, Metro Vancouver is constructing three air management facilities along the South Surrey Interceptor that will treat and significantly reduce odour. These facilities will also reduce corrosion and extend the service life of the sewer system. One of these facilities will be built under the Alex Fraser Bridge.</p><h3>Why do sewers smell?</h3><p>Odour produced in sewers is common and from the natural decomposition of organic matter.</p><h3>How will the air management facilities treat these odours?</h3><p>The facilities will be designed to minimize or eliminate odours, using biological treatment and activated carbon (charcoal) to scrub the air. Activated carbon is a natural product, is completely biodegradable and is used in home air filters. Once air is treated inside the facility and stripped of odour, it is dispersed through the vent stack. It is unlikely that residents will be able to detect any odour from this facility.</p><p>Metro Vancouver staff will monitor these facilities throughout the year to ensure smooth and quiet operation.</p><p><a href="/services/liquid-waste/ConstructionDocuments/amf-alex-fraser-bridge-factsheet.pdf" target="_blank">Fact Sheet - Air Management Facility - Under Alex Fraser Bridge </a></p></div>
