In this volume the description of the "Modernization of the Damkhodzhinsky Interregional Water Supply System with Connection to It Regional Centers of Navoiysky and Bukhara Areas" subproject is submitted. The description of the "Reconstruction of System of the Sewerage Termez" subproject is submitted in volume II (Books 1 – 6). 1 . Project purpose Development of the Feasibility study and implementation of the "Modernization of the Damkhodzhinsky Interregional Water Supply System in Connection to It Regional Centers of Navoiysky and Bukhara Areas" subproject are caused by need of the solution of problems of drinking water supply of the population of Navoiysky area.
