Some 20 trees including cherry, field maple and sweetgum have been planted in Manchester city to test their effectiveness against flooding.
The trees have been placed in specially designed pits which receive rainwater running off the road, pavement and some of the surrounding buildings. The rainwater is then used by the trees and excess water drains through the tree pit which is eventually returned to the sewer system.
The University of Manchester will be monitoring the trees to see how this affects the volume and speed of water entering the sewers. They will also be examining the levels of pollution in the water as it enters the tree pits.
Cllr Alan Quinn, cabinet member for the environment said: “The reaction in Prestwich to the Sustainable Urban Drainage Scheme (SUDS) involving the street trees has been really positive.
“People love the idea of using rainwater to water the trees and to improve the environment in general. We are already exploring the potential for other natural flood management projects in Bury.”
Pete Stringer, City of Trees, added: “Street trees don’t just change the look and feel of a street, town or city centre, but they bring a whole range of benefits including combating climate change, and improving our health and wellbeing. By planting street trees we can really help to transform our towns and cities into attractive places for people.”
