Managing Surface Water Quality for The Water Framework DirectiveThe European Union WFD: Overview

First published in December 2000.Transposed into English Law in December 2003.Introduced concept of “good status” for water bodies (by 2015),River Basin Management Plans & 6 Year Review Cycles.Described as: “The most important piece of European water legislation ever” but also “undeliverable in full.”Which will prove to be correct?

Improved Surface Water Quality Through Bioremediation from Plants: Green Roof Technology is Sustainable Drainage Potential Unrealised

“Bioremediation is a natural surface water cleansing method utilising the biological and biochemical processes available from flora “

Sustainable Development & the Role of Sustainable Drainage: The Brundtland Definition; A Strategic Challenge for Surface Water Management

“Sustainable development is development that meets theneeds of the present without compromising the ability

of future generations to meet their own needs.”

Former Norwegian Prime Minister, Gro Harlem Brundtland, “Our Common Future”1987

There is no “silver bullet”!!
