Water Supply Configuration and Water Losses - Nikšić Waterworks Case Study
Keywords:water supply, water losses, distribution network, pumping station, water tank, model calibration
Nikšić is the second largest city in the Republic of Montenegro, and the drinking water supply is secured from a nearby carstic groundwater resources. This paper provides an overview of activities related to defining of measures which will lead to a gradual increase in reliability and efficiency of the water supply system operation. This included analyses of the present condition of the water supply system, water consumption and water losses in the system, which led to the development and calibration of a water supply distribution system model. Additional field investigations were performed in order to further investigate the current levels of water consumption and water losses in the system and provide a relevant data set for calibration of the model. Analyses revealed a high level of water losses, and various measures have been proposed aiming, not only to reduce water losses, but also to reduce power consumption and improve efficiency and reliability of the water supply system operation.
