Abstract
Under thhe drought conditions that have occurred in Bulgaria during the last decade, agricultural use of non-conventional water may be an important resource. This is a specific case of simultaneous purification and utilisation by soil ecological systems. However, using non-conventional quality water presents a number of ecological and health risks and poses problems connected with soil and surface and ground water contaminated and with producing crops of acceptable quality. Bulgaria's municipal, industrial, and rural wastewater reclamation and reuse, in addition to other non conventional water resources as sea water, drainage water and mineralised groundwater, may be a reliable source even in drought years and thus is capable of replacing potable used in agriculture. This paper reviews the work of the authors and their colleagues in assessing the irrigation potentials of waste water in Bulgaria.
