Seeking Professional Excellence in Water Management: Case Study on Trincomalee Water Supply Scheme

Abstract

The Naval Dockyard Trincomalee is considered as the most strategic and important Naval Establishment of the Sri Lankan Navy. Naval Dockyard Trincomalee was established by the British, during the colonial era. Trincomalee naval water supply scheme was constructed in 1942 to accomplish the water requirement of naval Dockyard and Trincomalee town area. Although this system is more than 75 years old, it provides purified water requirement of Naval Dockyard and few other users within Trincomalee town, even today. The raw water source is Kalamatiyankulam reservoir, which has capacity of 47,029,300 Cubic meters. The water transmits to the Andamkulam purification plant only through the gravitational force and the energy increment by reducing the diameter of pipe. Similarly, the purified water also distributes to Naval Dockyard and other surrounding areas. The entire process is free from pumping, though the pumping station has been designed in original drawings. At present, water demand of Naval Dockyard has increased due to the rapid expansion of military infrastructure with the community. The objective of the study is to analysis the sustainability of the Trincomalee naval water supply scheme with emerging demand of water. This study concerns direct relationship of the current water demand with existing water supply in order to the factors such as flow rate, wastage, etc. Whilst, analysing the best feasible solution for improvement of existing scheme will be determined based on the quantitative data such as rainfall, population, and flow rate. Furthermore, possibility of contributing to the national water distribution network through state agencies will also be analysed as the conclusion of this study. Finally, the paper presents to a substitution plan for water transmission and distribution considering the future demands of Naval Dockyard and Trincomalee town area. This study focuses on how best to collaborate professionalism to the social demand with view of balancing and sustaining the water resources.
