Study of Waterworks of Phuentsholing Thromde

Abstract

The study is undertaken to assess the current situation of the Thromde water supply and suggest measures to improve the system. As per the data collected and a thorough analysis, the quantity of water available from the treatment plant should be sufficient to meet the current demands of the consumers; however, the current situation says otherwise. The water available to the users was insufficient. This incongruity in the supply and demand is attributed to excessive leakage from the old and corroded water pipelines and poor management. The most severely affected areas are the Public Works Department (PWD) and Royal Bhutan Army (RBA) colony. After carrying out an extensive and detailed survey of the water supply system in these areas, replacement of old pipes with new ones was suggested. Increased diameters and also addition of intermediate storage tanks were recommended. It was also found out that most of the distribution and service C.I. pipe lines were old and corroded which might contaminate the water. However, the water quality test conducted showed that there is no contamination in the distribution system. The data also suggested that the management needs to continuously monitor and supervise the water distribution for an effective water supply system. A new source also needs to be identified for meeting the expected population increase.
