The Abstraction Incentive Mechanism (AIM) is an Ofwat scheme to reduce abstraction from sources that are considered to be environmentally sensitive. Thames Water has implemented AIM since April 2016.
AIM’s objective is to encourage water companies to reduce the perceived impact of water abstraction at sites that are considered potentially environmentally sensitive and is designed to complement existing management tools e.g. National Environment Programme Sustainability Reductions, Hands Off Flows.
Implementing AIM should not impact security of supply or deployable output and there should be no capital investment for the scheme. Thames Water has implemented AIM at sites where it was not cost beneficial to undertake licence reductions using the existing management tools. To identify the final sites selected a comprehensive review of all potential environmentally sensitive abstractions was completed which can be downloaded below.
