Environmental investigations - supply

From 2010, the Environment Agency has identified eight investigations into the effects of abstraction and of impoundment by reservoirs on river flow.

These will be completed by 2013 and, should mitigation or reduction in licence be required, this will be considered in the 2014 Water resource management Plan and the AMP6 Business plan.
