A new biosolids dewatering facility at Iona Island Wastewater Treatment Plant in Richmond will help Metro Vancouver to more efficiently use wastewater as a resource, and is an important step as the regional district embarks on critical upgrades to the treatment plant.
The facility will mechanically dry the solids left after primary wastewater treatment, turning them into beneficial biosolids. Land that was previously used for biosolids drying and storage will be reclaimed for plant construction and ecological restoration projects.
The lagoons where solids are currently stored after primary treatment will be transformed into clean, freshwater ponds that will benefit a wide range of species, including migratory birds.
Testing and commissioning is underway and the new facility is expected to begin full operation in late 2022.
