Local Action: How sustainable drainage can improve urban environments | RTCC – Responding to Climate Change


Rain gardens can slow and clean urban stormwater. From rtcc.org.

This post from Tierney Smith covers and interview with Sue Pritchard from the Wildfowl and Wetlands Trust. Pritchard is working on implementing “sustainable drainage systems” in the Pymmes Brook Watershed in London. These systems mimic the flow of water in natural systems, where it has an opportunity to be absorbed by soil and treated by plants rather than running off of hard surfaces into a drainage system before being dumped into a river. This allows for aquifers to recharge, treats the water naturally, reduces localized flooding in traditional drainage systems, and can provide wildlife habitat. The design elements Pritchard is working to implement on the Pymmes Brook include “rain gardens, ponds, swales and detention basins.” However, Pritchard knows that if there is no community support, these places can quickly become trash dumps. That’s why her organization has partnered with ten area schools to build the systems, and turn them into outdoor classrooms for studying water systems and the flora and fauna that inhabit them. This is a great program for the students, the brook, and the community as a whole.
