Iona Island Wastewater Treatment Plant ProjectsIona Island Wastewater Treatment Plant Projects<div class="ExternalClass2E9DDD35447346A79F508B887F2EFE19"><p>The Iona Island Wastewater Treatment Plant is being upgraded to ensure continued protection of public health and the environment in a growing region.<br></p><p>Metro Vancouver wants to ensure the wastewater treatment plant makes a positive contribution to the health and well-being of people and the environment. A number of ecological restoration projects are planned in coordination with the plant upgrades. <br></p><h3>About the treatment plant </h3><p>The Iona Island Wastewater Treatment Plant was built in 1963 and today serves approximately 750,000 residents. The plant serves residents in the Vancouver Sewerage Area, which includes Vancouver, parts of Burnaby and Richmond, the University Endowment Lands, and UBC. The facility processes about 200 billion litres of wastewater each year. </p><p> The upgraded plant and complementary ecological projects are being designed to provide:</p><ul><li> <strong>Tertiary wastewater treatment</strong> to improve the treated wastewater quality being discharged to the Salish Sea</li><li> <strong>Ecological restoration projects</strong> to restore Iona Beach Regional Park’s diverse and sensitive ecosystems, build climate resilience, increase park visitor connection to nature, and create integration between the wastewater treatment plant and Park</li><li> <strong>Resource recovery opportunities</strong> to help support the region’s carbon neutrality objectives, by recovering important resources such as reclaimed water for non-potable uses, and biogas captured and used at the plant to generate heat for operations as well as supply for renewable natural gas to the Fortis BC natural gas distribution system</li><li> <strong>Extensive ground improvements</strong> to protect the plant from earthquake events and account for future sea level rise this century</li></ul><p>​The Iona Island Wastewater Treatment Plant Projects are in the early works and preliminary design phase, with work to prepare the site underway.</p></div>City of Richmond



Early works and priority activitiesEarly works and priority activities<div class="ExternalClass7791B8C435C24657AD2860FD34DBD9AC"><p>Metro Vancouver continues to deliver early works and priority activities to prepare the site and inform design. Visitors to xʷəyeyət /Iona Island may see crews conducting work related to the following activities:</p><ul><li>Clean out of treated sludge lagoons west of the existing treatment plant<br></li><li>Design of a barge berth for transportation of construction materials to and from Iona Island</li><li>Removal of biosolids stockpiles east of the existing treatment plant</li><li>Geotechnical investigations, on land and in-water around Iona Island</li><li>Technical studies for ecological restoration projects</li><li>Work to obtain required permits and approvals</li><li>Improvements to roads and upgraded electrical servicing on Sea Island and Iona Island<br></li></ul><p>We will keep you updated about what to expect on xʷəyeyət/Iona Island and in the surrounding area as the projects progress.</p>​<span id="ms-rterangecursor-start"></span><span id="ms-rterangecursor-end"></span><br></div>
Lagoon clean outLagoon clean out<div class="ExternalClass65C8BB8C08F5416099FB5E64A6A4713A"><p>Over the next seven years, the existing treated sludge lagoons will be cleaned out to prepare the site and support wastewater treatment plant upgrade construction. Each area will be re-purposed for alternate uses during and after project construction. The sludge lagoons will eventually be transitioned to wetlands, terrestrial habitat, and park amenities that will be integrated into Iona Beach Regional Park.</p><p>During clean out operations, a barge floats on the lagoon surface and dredges out biosolids from the bottom of the lagoon. Liquid biosolids are then pumped through two centrifuges located on a concrete dewatering pad to separate the water and biosolids.</p><p>In spring 2023, water is expected to be removed from the southeast lagoon. Clean out operations on the other sludge lagoons will begin in spring 2024 for approximately nine months, and occur yearly until 2030. Work will occur from 6:00 am to 7:00 pm, Monday to Saturday.</p><p>Metro Vancouver will continue to monitor and mitigate noise, odour, and wildlife impacts throughout operations.</p>​<br></div>
Barge berth designBarge berth design<div class="ExternalClassF5BA0A72250046298DA0D5F6DDE4A483"><p>Metro Vancouver is planning to reduce traffic impacts related to construction of the project by bringing in a barge to transfer materials like sand. It will require construction of a temporary barge berth, which will: </p><ul><li>Improve safety for cyclists, pedestrians, and vehicles travelling to xʷəyeyət (Iona Island) </li><li>Reduce both traffic throughout the Lower Mainland and greenhouse gas emissions </li><li>Help to minimize costs and delays​​​</li></ul></div>






Community engagement

Metro Vancouver is working closely with key stakeholders, the public, and xʷməθkʷəy̓əm (Musqueam) Indian Band to consider their interests and the project’s fit with the community.

Metro Vancouver will:

  • Provide information in a timely manner
  • Listen to interests and priorities
  • Collaborate on how the plant is integrated with Iona Beach Regional Park and the surrounding environment
  • Collaborate on resource recovery opportunities
  • Take feedback to the project team and report back on how it has been addressed
  • Establish a single point of contact the community can reach to discuss the projects

Ongoing opportunities for engagement will continue to be provided. Please see the Community Engagement section below for previous engagement activities.

Initial monitoring has already demonstrated project success, with high rates of juvenile salmon passage, including Chinook, chum, pink, and sockeye salmon, and with no impacts detected to navigation in the main river channel. </p><p>Construction of the second breach is expected to occur in fall 2023, along with site maintenance and remediation. Breach locations are informed by ease of fish passage through jetty midpoint, accessibility, construction feasibility, cost, and stakeholder and First Nations feedback.</p> <br> <p> <strong>Background</strong> </p><p>The North Arm Jetty was constructed in 1916 to aid in navigation, creating a 6.8-kilometre-long barrier and altering connectivity between the North Arm of the Fraser River and the rest of the estuary. This barrier interrupts the natural movement of juvenile salmon and other fish species, forcing them directly from freshwater river areas into the deeper waters of the Strait of Georgia, bypassing the brackish marsh, tidal channels, and mudflat habitats upon which they rely to make the transition from freshwater to saline ocean water. The jetty is under the jurisdiction of the Vancouver Fraser Port Authority. It extends from the northwestern tip of Iona Island, and is located directly adjacent to Iona Beach Regional Park.</p> <br> <p> <strong>Shared Goals</strong></p><p>The North Arm Jetty Breaches Project is supported by Metro Vancouver and is aligned with the ecological restoration goals of the Iona Island Wastewater Treatment Plant projects.</p> <br> <p> <strong>Project Partners</strong></p><p>Ducks Unlimited Canada, Tsawwassen First Nation, Lower Fraser Fisheries Alliance, Pacific Salmon Foundation, Vancouver Fraser Port Authority, with support from Metro Vancouver.</p><p>Funding for Raincoast’s project provided by the Coastal Restoration Fund and the BC Salmon Restoration and Innovation Fund.</p> <br> <p> <strong>Contact Raincoast Conservation Foundation</strong></p><p>Email Dave Scott at <a href="" target="_blank"></a></p><p>Learn more about Raincoast's work in the Fraser River estuary at the <a href="" target="_blank">Raincoast Site</a>.</p> <br> <p> <strong>Project Information Session</strong></p><p>A project information session, cohosted by Metro Vancouver, was held on May 27, 2021:</p><ul class="fa-ul"><li><span class="fa-li"><i class="fa-light fa-file"></i></span> <a href="/services/liquid-waste/Documents/raincoast-information-session-presentation-2021-05-27.pdf" target="_blank" title="Raincoast Information Session Presentation">Raincoast Information Session Presentation</a></li>​ <li><span class="fa-li"><i class="fa-light fa-file"></i></span> <a href="/services/liquid-waste/Documents/raincoast-information-session-summary-2021-05-27.pdf" target="_blank" title="Raincoast Information Session Summary">Raincoast Information Session Summary</a></li>​ <ul> </ul></ul>​<br></div>
