Thailand – Metropolitan Waterworks Authority (MWA) is preparing to make capital investments totaling 7.5 billion baht between 2009 and 2011 to expand its tap water capacity and improve the quality of its tap water distribution.
MWA governor Chareon Chaikittisilpa said the state enterprise intended to increase tap water capacity by another 800,000 cubic metres per day in 2011 from the current 5.5 million cubic metres to accommodate future demand from increased population in the next decade.
The investment, part of which would funded by loans from commercial banks, would be allocated in detail by the end of this year.
Peak demand for tap water in the Greater Bangkok area served by the MWA is currently about five million cubic metres a day, and has been increasing by an average of 3-4% a year.
According to Mr Chareon, as part of the tap water distribution improvement plan, the authority would be installing a geographic information system (GIS), which would allow MWA technicians to identify the sources of tap water leakage across its 25,000-kilometre pipeline network covering Bangkok, Nonthaburi and Samut Prakan.
Computerised equipment to assist bill collectors will also be installed to ensure accuracy of water volume and revenue forecasting.
