In the future, we can anticipate heavier fall and winter rains. Heavier rains mean more water going down our storm drains carrying pollution and creating erosion within our waterways like Cougar Creek. To reduce pollution and erosion, Delta has installed rain gardens along our streetscape where possible.
Rain gardens are planted areas designed to receive rain water flows. A rain garden allows water to filter into the ground as opposed to flowing directly into storm drains and watercourses untreated. Rain gardens can cut down the amount of pollution reaching creeks and streams by up to 30 per cent.
Delta's Engineering Department has been working with local stream keepers to design, install and maintain rain gardens at Delta's elementary schools. The first rain garden was installed at Cougar Canyon Elementary School in 2007. Check out our School Programs to learn about our Rain Gardeners Classroom Program.
Adopt-a-Rain-Garden is a garden maintenance program. Residents, families, local groups, clubs, and other organizations work with the Corporation of Delta to ensure our community's rain gardens are kept up and working properly. This program helps protect nearby fish habitat and keeps our neighbourhoods looking great.
Participating volunteers adopt a rain garden in their neighbourhood, pledging to perform simple garden maintenance (e.g. weeding) throughout the year to help keep our rain gardens healthy and beautiful. Volunteers work under the guidance of the Engineering Department, which provides volunteers with an initial orientation.
