Rehabilitation studies about storage tanks: a case study

Çağlar, Meriç
One of the most important factors, while designing a water distribution system, is the storage tank capacity in terms of costs. When the storage tank volume is increased, more water can be stored, the water distribution system works more efficiently, and energy costs can be decreased. Population growth, interest rate, the cost of the water distribution system elements and energy prices have major effects on the storage tank capacity. The software model of the study area, N8.3, was optimized, and the daily energy costs of the 24 hour period simulation analysis were analysed. Costs of 24 hours period simulation of the scenarios, daily energy costs, were calculated for the years between 2015 and 2085. Results showed that the daily energy costs of the network decreased if the storage tank size increased. When the storage tank capacity is large enough, the storage tank can store more water in the lowest price intervals, and feeds the network for a longer period in the highest cost intervals. The requirement of the largest storage tank, which is selected within the scope of this study, occurred at the year 2055 when the interest rates are low. When the interest rate are high, the annual cost of the storage tank is greater than the annual costs of low interest rates. As a result of this, the largest storage tank requirement occurred later, after the year 2075, when the interest rates are high.
