  • Possibilities for water conservation in Bulgaria
  • Bulgaria ; Consumption ; Demand ; Water ; Water economics ; Water management ; Water use
  • Existing water resources can become inadequate if water losses are too important and if there is an irrational use of water. Water conservation could solve some water supply problems by providing more reasonable water consumption and additional time
  • for development of new resources. The possibilities for reducing water use and the need for developing a national conservation program are discussed. An analysis of the variables which affect water use is performed. Developing of water-use efficiency standards
  • for plumbing fixtures and conservation-oriented water rates and measures are proposed.
