Water Treatment Plant

Water treatment plants are based on coagulation, flocculation and disinfection processes and found to be most cost effective in treating large quantities of water. However, they entail large infrastructure costs which is difficult to raise in rural regions of developing countries and are generally installed using government funding. Hence, centralized treatment is available only in the metros of developing countries and mainly benefit the urban population. The transportation cost of water to the centralized treatment plant and from the treatment plant to the individual households is another major expense which limits its benefits to regions which are situated away from the treatment plant. Hence centralized treatment plants are generally installed near the freshwater resources (rivers or lakes) and benefit the people living closer to these water bodies.
