A wastewater treatment plant is needed to treat the sewage collected from the comprehensive collection network. Selection of the location of the treatment plant has to take into consideration the availability of land, the future expansion of the built up areas, the topography of the area and the availability of agricultural land. The treatment process has to produce effluents that meet required standards to be used for irrigation purposes. For rural communities, septic tanks and other new technologies for rural areas, other than cesspits for the disposal of domestic wastewater is recommended. Restrictions and control measures should be imposed on industries to reduce the level of pollutants that enter the environment.
Industrial waste has to be treated at source before disposal into collection networks.
Stone cutting facilities are known to consume large quantities of water. Treatment and reuse of generated wastewater will save water and prevent environmental pollution. Installation of a separate drainage system for rainwater is recommended, in order not to mix with the wastewater. The collected rainwater can be used for agricultural purposes. Irrigation with treated wastewater as an additional source of water should be encouraged among farmers.
