Avoided Runoff

Stormwater and localised flooding can cause excessive damage and repair costs within urban areas. Trees reduce this by intercepting rainfall, capturing the water within their canopy on the leaf surfaces and by directing the flow of water down the trunk and into the soil. This reduces the volume of water entering the drainage network which would otherwise require treatment by the local water authority.

The public trees within Islington prevent an estimated 13,000m3 entering the sewerage systems each year, equivalent to over 5 Olympic swimming pools of water!
