Economies Of Wastewater Reuse

The rapidly increasing population the technological and industrial booms have brought enormous problems and degradation of the environment. Water pollution and water scarcity is an emerging problem in Pakistan. Pakistan has no effective collection and treatment of domestic and Industrial Wastewater. Due to the shortage of water in Pakistan we should go for new water resources. Wastewater reuse after treatment is a reliable water resource for irrigation. In case study of Faisalabad wastewater of the city is treated by using waste stabilization ponds and evaluated the effluent quality as a function of cost. The results shows that by increasing the number of ponds the ultimate cost of the project will increase and area requirement will be more six 6 parallel series of anaerobic facultative than that will be high in coliform but if one maturation pond is added then coliform reduces but not in the range to WHO guideline for unrestricted crops by adding four ponds the values will be in range but adding more maturation ponds will increase cost of the project.
