This report describes various aspects of the drinking water supply system for Leh town. Even though water shortage is the leading concern and fear of people, and large water projects are being implemented, there is a general lack of information and clarity about water demand and supply, and management of water systems in Leh. The research team, other stakeholders, and experts, had varied opinions on this topic and also many ideas on how it should be improved or changed, but the purpose of this report is to describe the system as it is. This report is meant to separate facts from fiction and opinions, and therefore, ideas and suggestions for the future have not been reflected in this report. We believe that once a shared factual basis is established across all key stakeholders in this matter, then ideas and opinions can be discussed in a more objective manner, to determine a path to improve water security and sustainability in Leh.
