The paper presents modern approach on application of drainage and water deep wells for pumping of the drainage water for irrigation. Author is presenting theoretical background for division of the irrigated areas using geomorphologic, water quality, soil characteristics of the irrigated areas. In Central Asia drainage water formation is natural part of the irrigation development due to the conditions of the soil, irrigation system. Therefore, developing effective means of capturing and re- use of the drainage water must be a part of water management strategies.
Principles of the division of the irrigated areas could be easily applied for any of irrigated areas of the world, including Central Asia. The approach also applies modern technologies, namely Techniques of Geographical information systems (GIS) and Remote Sensing (RS). Three distinctive types of the irrigated areas where drainage water can be used in different ratios: full use, partial use and non- usable. Applying GIS/RS methods author also have produced map of drainage water re- use for Bukhara oasis.
