It is widely accepted that the provision of access to safe drinking water and sanitation services for the world's poor is one of the great developmental challenges of the modern era. There is a need to establish mechanisms that enable the human right to water to be satisfied in developing states. This article will discuss how the General Agreement on Trade in Services (GATS) can be used to facilitate the promotion of quality and affordable water services to developing states. Indeed, it is argued that the WTO and the GATS are the most appropriate mechanisms to successfully satisfy the human right to water in developing countries. The challenges of adopting a multilateral model will be explored, and the importance of adopting capacity-building issues and pricing challenges within an amended GATS framework will be addressed. The nexus between the GATS and the trend towards privatisation will also be considered. The aim of this article is to contribute towards a greater understanding of the role that international trade law in general, and the GATS in particular, can play as part of a holistic response to the immense problems (present and future) relating to water resources in LDCs.
