Hydraulic analysis of water supply system without tanks

Abstract

Whether a particular water supply system needs a tank or not depends primarily on the available capacities of the springs used for water supply and their altitude at which they are located in relation to the inhabited place. If the spring capacity is larger than the maximum water consumption per hour, there is no need for tank. Alternatively, the requirement of a tank in order to provide 100% provision for the water supply system is mandatory. In practice, the water supply systems which have not required building of tank for equalizing the consumption with the inflow of water have been very rare. Such example of a larger water supply system in our country is the water supply system of the town of Gostivar and the surrounding inhabited places, which will actually be the subject of analysis in this paper. According to the previously stated, the aim of this paper is, through the hydraulic analysis of water supply system without tank, to define how big the maximum and minimum pressures are in the water supply network, the losses of water in the system, and by that the possible disadvantages/advantages of the water supply systems without a tank to be considered.
