Berkovitsa is a small town located in Berkovitsa Mountain. The town is situated in an area with a dense hydrographic network but still encounters difficulties in water supply. The purpose of the study is to make an analysis of changes in water demand in the town of Berkovitsa, assessed by the Water Stress Index. The water supply in the municipality of Berkovitsa is taken care of by the operator "ViK Berkovitsa" EOOD. The separate territory of ViK Berkovitsa EOOD consists of a total of six different sized water supply systems (WSS), one of which is WSS Berkovitsa � for the town of Berkovitsa. The WSS Berkovitsa is supplied with water from several water sources, which receive water from mountain catchments. These water sources are surface river catchments, shallow underground water sources and "Srechenska Bara" Dam. For this study is used data for intake capacity of water sources and for water demand in the town of Berkovitsa. The data for the resource of the water sources is based on information from the issued water permits of Danube River Basin Directorate Pleven. The data for the water demand � from the Business plan for the development of the activity of the "ViK Berkovitsa" EOOD for the period 2017-2021 and from the forecast for the demand made in the regional Master plans for water and waste water. Then with this data is calculated the Water Stress Index for water supply of the town of Berkovitsa, which takes into account the percentage of intake water to the available water resource. In order to avoid water stress, this ratio should be under 20%, but for the town of Berkovitsa is around 75%. The study shows that the main cause of high water stress is large water losses. Some comparisons with the Business Plan and Master Plans are discussed. Conclusions have been made in connection with the reduction of water stress on Berkovitsa town's water sources. |
