We have a target to capture and treat 90% of Vancouver’s average annual rainfall by using green rainwater infrastructure tools and design guidelines on public and private property.
In the natural environment, rain is absorbed and filtered by plants and soils. In cities, this natural water cycle is disrupted and rainwater flows across pavement and rooftops.
This water picks up pollutants which end up in our waterways causing negative impacts on water quality and wildlife.
Green rainwater infrastructure brings nature into the city, to capture and clean our rain water before returning it to our atmosphere and our surrounding oceans and rivers.

Rain City Strategy
We are working on a strategy to:
- Improve water quality
- Enhance Vancouver’s resiliency and climate change adaptation
- Use rainwater as a resource
- Support neighbourhood livability and biodiversity

Rain City Strategy approved
On November 5, 2019, City Council unanimously approved an ambitious green rainwater infrastructure and urban rainwater management initiative called the Rain City Strategy.
The strategy and its action plans reimagine how we can manage rainwater, representing a significant opportunity to take bold strides toward becoming a water-sensitive city.

Shaped by water
Several members of our engineering department toured the Netherlands to learn more about the green infrastructure and water technologies.
Vancouver's Rain City Strategy
We've has set a target to capture and treat 90% of Vancouver’s average annual rainfall by using green rainwater infrastructure tools.
Our vision: Vancouver’s rainwater is embraced as a valued resource for our communities and natural ecosystems
What is green rainwater infrastructure
Green rainwater infrastructure mimics natural water processes. It works with plants, soils, trees, and built structures to capture and clean rainwater before returning it to our waterways and atmosphere.
Benefits
Green rainwater infrastructure features
By City of Vancouver
View different types of green rainwater infrastructure around the city.
-
Green roofs
By City of Vancouver
These living roofs covered with plants and trees collect, absorb, and return rainwater to our atmosphere. Green roofs provide habitat for wildlife and pollinators.
-
Rain-friendly streets
By City of Vancouver
Porous pavement absorbs rainwater and soil cells store water and create space for tree roots to grow and absorb water beneath our sidewalks and traffic lanes.
-
Swales
By City of Vancouver
Swales are shallow channels alongside roads that use soils and plants to direct and slow water allowing it to absorb into the ground and atmosphere.
-
Rain garden
By City of Vancouver
These gardens are sunken into the ground and lined with native plants, grasses, trees, and stream beds that absorb and clean rainwater that runs off our streets and sidewalks.
-
Parks
By City of Vancouver
City parks are full of plants, trees, and flowers that soak up and clean our rainwater. They act like natural wetlands in our urban environment!
