76 Wastewater Treatment Technologies in Nepal

چکیده
Though the need for appropriate wastewater management technologies is undoubtedly a realized issue, so far there has been very little action taken towards wastewater treatment in Nepal. The centralized approaches of wastewater management have been unsuccessful as the existing traditional lagoons or activated sludge type wastewater treatment plants are not functioning or partially operating at far below capacity. The major causes of failure are high capital investment, high operational and maintenance costs, complexity of the systems, be short of spare parts and lack of skilled resource persons. It creates opportunities to employ decentralized systems for wastewater reuse as well as resource recovery. This review emphasizes on the state of wastewater treatment units and prospects of sustainable decentralized wastewater systems including constructed wetlands in Nepal.
