Source balancing
At the beginning of November, for the purpose of reviewing the condition of the water supply network and primarily the capacity of the Krupica spring from which consumers of the settlements of Miljevina, Jeleč, Rataj and Ocrkavlje near Foča are supplied, flow measurements were performed.
Based on the recorded current situation in the field and the assessment of the measurement possibilities, ie the satisfaction of the basic parameters for accurate measurement, the flow meters and current measurements were set up at 9 (nine) measuring points.
The measurement included parts on the pipeline where measurement was available, ie where the pipeline was visible and where there were conditions for satisfactory measurement with a flow meter.
Flow measurement at the inlet to tanks and relief chambers
Flow measurements were also performed at the relief chambers and the Miljevina drinking water tank.
Based on the measurement results, a needs analysis was performed for the total number of inhabitants in the consumption area, which amounts to 1700 inhabitants. According to the results of flow measurement, it can be concluded that at this moment the source would have sufficient capacity to supply the consumption area, noting that the current measurement was performed and that the measurement should take several days to make the most accurate conclusion. In that way, the hourly and daily unevenness and the minimum night flow would be determined, and on the basis of which more accurate conclusions could then be made.
During the measurement, certain differences were noticed at the temporary measuring points, and investigative works should be continued and leak detection.
The current measurements made for the settlements of Rataj, Ocrkavlje and Miljevina are only introductory and for a more detailed finding of losses it is necessary to make a 24-hour or 48-hour measurement in order to be able to analyze minimum night flow, and whose values are most relevant for the analysis of losses for the measured area.
For metering works on this water supply system, a report was prepared with an estimate of the required quantities of water for these suburban settlements in Foča, as well as notes for the execution of certain actions. The recommendations are in terms of the work required in order loss reduction and better water supply in the area
