Langley Waste Water Treatment Plant
The expanded Northwest Langley wastewater treatment plant will service approximately 230,000 people by 2026, including residents and businesses in Maple Ridge and Pitt Meadows, while continuing to provide secondary treatment.
The large site is far removed from directly adjacent population centres. A major consideration in the approach to site design is the preservation of a green open space through the central plant area to maintain a visual connection to the Fraser River and Barnston Island. The infrastructure alongside the Fraser River will be set back by 85m to meet geotechnical requirements.This will provide a substantial buffer to integrate the plant into its surrounding context.
Public space, wetlands, plants, landform, and interpretive elements are designed to integrate restorative features and, occasionally, to provide an accessible and integrated public face for the plant. An elevated mound at the northeast edge of the site is proposed to be incorporated
into the initial phase of development, becoming an integral interpretive element of the site while providing temporary storage for fill. Wrapping along the edges of the site, a multi-use path is designed to provide a restorative element for visitors to the area while connecting to the Trans Canada Trail and affording access to the Fraser River.
