项目陈述
Project Statement
Iona岛污水处理厂（IIWWTP）与xwəyeyət地区公园堪称大温哥华地区有史以来规模最大的基础设施工程。改造升级后的污水处理厂不仅能够满足联邦法规的要求，同时也为当地创造出一次重要的机会，为当地带来了重大的利益。除了对污水处理厂进行升级外，该项目还致力于恢复河口的动态生态系统，以增加岛屿对气候变化的适应能力，区域公园内的教育和娱乐设施也得到了改善与增强。本项目为当地带来了一次变革性的机会，将城市基础设施与生态恢复和气候适应相结合，为当地创造出了一处意义非凡且可持续的工业遗产。
The Iona Island Wastewater Treatment Plant (IIWWTP) and Regional Park Projects collectively represent the largest capital works project ever undertaken by Metro Vancouver. Driven by the need to upgrade the existing WWTP to meet federal regulations, the projects also offer a critical opportunity to provide significant benefits to the region. In addition to WWTP upgrades, the projects will restore dynamic estuary processes, increase the island’s resilience to climate change and expand educational and recreational offerings in the regional park. These projects are a transformative opportunity to integrate urban infrastructure with ecological restoration and climate adaptation and will create a significant, ongoing legacy for the region.

项目说明
Project Narrative
加拿大列治文市(Richmond BC)的Iona岛污水处理厂（IIWWTP）是一处人类和生态系统交叉的复杂地点。现有的处理设施位于弗雷泽河河口，是北美西海岸仅进行初级废水处理的最后几家工厂之一，设施的对面则是xʷməθkʷəy̓əm(Musqueam)原住民部落。河口现有的基础设施，包括堤防和防波堤，破坏了自然沉积物和淡水的流动，直接影响了鲑鱼幼体和其他物种的生存。此外，气候变化也对该地区构成了重大的威胁，预计到2100年该地区海平面将上升1米。
对现有的污水处理厂进行必要的升级，以满足联邦对废水排放质量的规定，这是推动本次污水处理厂改造项目的主要动力。然而，此次辅助工程也提供了一次重要的机会，能够为该地区带来重大的利益。本项目的设计概念由一系列相互关联的改造策略构成，包括：污水处理厂升级、资源回收、公园和社区一体化战略，以及生态恢复策略。在生态再生方法的指导下，改造后的污水处理厂不仅能够满足法规要求，甚至能够超越规定的水质处理标准，为周围社区和生态系统做出积极的贡献。
生态改造工程将恢复河口的动态生态系统，增强原生和新生物种的弹性，使众多物种受益。基于生态系统的防洪战略将增强河口地区抵御气候变化影响的能力，并保护新的基础设施。公园和社区的整合策略将在污水处理厂和周围的Iona海滩地区公园之间建立有益的联系。工厂的布局将响应生态敏感地区和社区的愿望，在减少工业基础设施对周围自然环境的视觉影响的情况下，增强当地的教育、娱乐与公园体验设施。
综合设计过程汇集了多学科专业知识，使项目的目标与改善水质、资源回收以及与公园和社区的整合保持一致。在项目初期的定位阶段，就展开了广泛的社会参与，参与者包括与IIWWTP项目相关的各种群体与组织，包括：周围的邻居、公园用户群体、当地政府，以及土著群体。这种协作过程将生态栖息地的恢复、传统资源的获取，以及对xʷməθkʷəy̓əm(Musqueam)原住民文化习俗与民族智慧的宣传，从早期设计阶段就开始整合。这一过程还展示了如何利用跨学科的合作与司法工具开展包容性工作，平衡并整合社会、生态、技术和气候的相关需求。通过持续的综合设计和交付过程，污水处理厂项目的工作将进一步发展和演变，直到2038年，污水处理厂和公园的持续运营将不断改善。
IIWWTP项目是通过保护和恢复人们赖以生存的生态系统和河流环境，为协调发展与自然迈出了创新性的一步。该项目彰显了长远的可持续发展眼光，促进了跨学科合作以及与土著部落的合作，通过以自然为基础的改造策略为该地区创造出重要的、持续的遗产。

Project Narrative
The Iona Island Wastewater Treatment Plant (IIWWTP) in Richmond, BC sits on xʷəyeyət/Iona Island, a complex site of intersecting human and ecological systems. Located in the Fraser River Estuary and across from xʷməθkʷəy̓əm/Musqueam, the existing treatment facility is one of the last plants on North America’s west coast with only primary level wastewater treatment. Existing infrastructure in the estuary, including dikes and jetties, has disrupted natural sediment and freshwater flows, directly impacting juvenile salmon and other species. Furthermore, climate change poses a significant threat to the region, with projections estimating one metre of sea level rise by 2100.
Required upgrades to the existing IIWWTP to meet federal regulations for wastewater effluent quality are the primary force driving the IIWWTP Projects. Yet, the ancillary works also offer a critical opportunity to provide significant benefits to the region. The conceptual design of the IIWWTP Projects has been developed as a portfolio of interrelated undertakings, including wastewater treatment plant upgrades, resource recovery initiatives, park and community integration strategies and ecological restoration projects. Guided by a regenerative approach, these projects will upgrade the existing plant to not only meet, but exceed, water quality treatment regulations, while making a net positive contribution to the surrounding communities and ecosystems.
Ecological projects will restore dynamic estuary processes and enhance native and novel habitats to benefit numerous species. Ecosystem-based flood protection strategies will increase resilience against climate change impacts and protect new infrastructure. Park and community integration strategies will enable meaningful relationships between the IIWWTP and the surrounding Iona Beach Regional Park. The strategies will ensure that the plant’s layout responds to ecologically sensitive areas and the community’s desire to minimize its visual impact, while expanding educational, recreational, and experiential park offerings.
An integrated design process brought together multi-disciplinary expertise to align the project’s goals of improving water quality, resource recovery, and integration with the park and community. Throughout the project definition phase, an extensive engagement process was undertaken to work with a variety of organizations impacted by the IIWWTP Projects, including neighbours, park user groups, local government, and Indigenous groups. This collaborative process has enabled priorities such as habitat restoration, traditional resource access, and recognition of xʷməθkʷəy̓əm/Musqueam cultural practices and knowledge transfer to be integrated from early design stages.
This process also demonstrated how to work inclusively across disciplines and jurisdictions to balance and integrate social, ecological, technical, and climate-related needs. Through the continuation of an integrated design and delivery process, work on the IIWWTP Projects will further develop and evolve until 2038, and continual improvement will be achieved through ongoing WWTP and park operations.
The IIWWTP Projects are an innovative step towards reconciling development and nature by protecting and reviving the ecosystems and flows that sustain us. These projects inspire a vision for interdisciplinary and Indigenous collaboration and nature-based solutions with the potential to establish a significant, ongoing legacy for the region.
