Water Environment Issues of Bangkok City, Thailand: Options for Sustainable Management

Chongrak Polprasert*

 
ABSTRACT: Bangkok is a major city, with an area of 1570 km2 and a population of 10 million inhabitants. Situated 2 meters above sea level, and lacking proper infrastructure and planning, Bangkok faces water management and water pollution problems. Presently, 91% of water demand is supplied from river water and 9% from deep wells. Increased rainwater harvesting would decrease problems of land subsidence, ground water contamination and dependence on surface water sources. Decentralized wastewater management systems would also be useful. Sustainable management of water supply and wastewater reclamation require synergistic interactions among government, private sector and community sectors.
