Water scarcity is a reality in many regions, irrespective of their climate. Reducing losses from Water Supply Systems (WSSs) is therefore an issue of worldwide environmental importance. In France, water suppliers are legally bound to reduce losses from their WSSs. One of the actions they are required to undertake is the creation of Loss Reduction Action Plans (LRAPs). In order for such plans to be successful, they need to suit the area to which they are applied. Their impacts on water bodies and the environment also need to be taken into account. This paper explains the approach developed by Irstea (at the request of the French Ministry of Ecology) to fulfil these objectives. The approach includes a guide to designing LRAPs, a method for creating a Water Abstraction and Discharge Balance (WADB), and an Analysis of Environmental Effects (AEE) relating to loss reduction actions, based on Life Cycle Assessment (LCA). The usefulness and the practicality of this approach are examined through two practical case studies. While the guide to creating LRAPs and the WADB are sufficiently developed for use by WSSs, the AEE still requires further improvement.
