Evaluation of water distribution network system and design of water treatment plan for phuntsholing city

Abstract

This Project primarily focuses on two main contexts: evaluation of the water distribution network system of Phuntsholing City and design of a water treatment plant. Presently, the city has been supplied with five water sources: three surface sources and two subsurface sources. Due to an unusual increase in population, water crises in the city have become a significant issue and a major concern for the government. Construction of water treatment plants and installation of borehole pumping systems were undertaken in order to eradicate water shortages, especially in the core town area, but the issue remains beyond control. Therefore, this Project would entirely describe the necessity of another water treatment plant, which will be located at Damdara, 1.45 KM away from the main town. Moreover, several defects in existing water distribution systems and corresponding remedial measures required to overcome these issues are proposed. The Project also focuses on the total discharge available from the city source and the actual requirement based on the population residing in the campus. Evaluation is also carried out using EPANET software.
