Rain Gardens Keep it Fresh

Jan 19, 2017

Delta's Rain Gardens help to put water back where it belongs... in the ground!

Since 2006, Delta's Engineering Department has been working alongside local streamkeepers and volunteers to design, install and maintain rain gardens throughout our community. 

What is a rain garden exactly? 

A rain garden gathers all the stormwater from streets, parking lots, and rooftops. This water, often polluted with oils, metals, and chemicals, is absorbed by the garden and cleaned by soil, plants, and micro-organisms. The cleaned water then flows through the ground and into our creeks and rivers, where salmon come to spawn. Cumulatively, Delta’s rain gardens are treating millions of litres of water ever year!

How can I get involved?

Volunteers can participate in Delta's Adopt-a-Rain-Garden program to ensure that  the gardens are working properly. By adopting a rain garden, volunteers pledge to keep the garden healthy by performing simple garden maintenance, like weeding, clearing the intakes of sediment so water can flow freely, caring for plants, and removing litter. Volunteers receive an orientation and ongoing support from Delta’s Engineering Department and the Cougar Creek Streamkeepers .

For teachers looking to integrate nature into their classroom, Delta staff have also developed a complementary rain gardener curriculum for grades 4 and 5 students. This program also relies on the help of hundred of Delta School District students who help the planting and the mulching at newly built gardens.   .  

Take a look at the amazing work done by students from Gray Elementary:
