Kura Water Purifier



      Demands for drinking water has increased sharply in Absheron Peninsula as a result of construction of new housing estates and micro districts, expansion of surrounding settlements and villages in Baku in the 60s of the last century. Two pipelines laid from Khachmaz and processed in Jeyranbatan Water Treatment Compound failed to meet the demands for water. Construction of Water Treatment Plants Compound on the coast of Kura and transmission of water pipelines from there to Baku was started following Order of Council of Ministers of the former Azerbaijan Soviet Socialist Republic.

  Implementation of the project was started in 1969 and completed in a very short time on the initiative of Great Leader Heydar Aliyev. The first shift of Kura Water Pipeline system was put into operation between 1970 and 1971 with intervals. 2 transmission mains were laid from Compound located near Small Talish village of Hajigabul region for supplying Baku residents with water after treatment. In the 1st phase supplying the capital with 3,2 m3 drinking water was not met the demand.

The 2nd shift of Kura Water Treatment system was constructed in 1980s for improving drinking water supply of Absheron Peninsula. In the 3rd phase (between 1984, 1986 and 1988) more 3 transmission mains were laid to Baku. The total capacity of the facilities is 9,5 m3(820 thousand m3 per day) including the 1st and 2nd shifts of Kura Water Treatment System are 3,3 m3(285 thousand m3 per day) and 6,2, m3 (536thousand m3 per day). Water shortage in Gunashli and Ahmadli was eliminated as a result of put in operation of the 2nd shift of Kura Water Treatment System.

     As to the principles of the Water Treatment Plants we should note that first of all water of Kura River is treated from silt in radial and horizontal sedimentations( there are 6 radial sedimentations in the first and 8 radial sedimentations in the second  Kura Water Treatment Plants). In the next stage water through screens is chlorinated and transmitted to Baku by lifting pumps. Lifting pumps are used again near Sangachal settlement in the 89th km of transmission main again for conveying water to Baku from long distance.

     In the frame of “Reconstruction of Greater Baku Water Supply system Project” rehabilitation work was carried out in Kura Water Treatment Compound financed by loan of World Bank (WB) and Europe Bank for Reconstruction and Development (EBRD). According to the project water quality processed in the compound was adapted to standards as a result of reconstruction of radial, horizontal sedimentations, screens chlorination and reagent buildings, lifting pump stations.
