Engineering-Oriented on Rural Water Supply System in North-Eastern Region of Thailand

Water and sanitation have been a high priority in the development agenda for Thailand. Nationally, access to an improved the sanitary water supply treatment in Thailand as a low 10% in 1973 to the current level of over 90%. Over has developed rapidly, but water supplies in rural areas have lagged behind. In rural areas, water quality and quantity remains a problem. In order to improved village water supply treatment system (VWST), the studies were conducted on 27 villages of rural water supply treatment systems from the four provinces in North-Eastern region of Thailand. These are including, Nakhon Ratchasima, Surin, Buriram and Chaiyaphum. Data were collected through structured interviews, observations and measurement. The initial design of VWST are responsibility of government organization such as department of water resources etc. Most of results were includes two mains of the process train selection by surface and ground water supply treatment systems. These not concerned on the raw water quality and quantity that were supplied. The development of VWST plants without the use of optimization provides on optimal structures, based essentially on the immediate response to the growing water demand of population. These non-optimal structures are translated into non-efficient systems in terms of design and operation. Inefficient pumps, inefficient pump combinations and inefficient pump scheduling are the three main problems that are commonly found in pump stations. Measures with and without investment in order to reduce costs and energy consumption are not presented.
