ABSTRACT

Quality of sewage waste water is assessed, used in irrigation purpose, to get the suitability of water for agriculture. Water samples were collected and analysed for various parameters: pH, odour, colour, turbidity, total hardness, iron (Fe), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Dissolved Oxygen (DO), Total Suspended Solids (TSS), and various metal ions. Biological assessment such as E-coli, total coliforms and faecal coliforms were also done. All the physicochemical parameters determined were found within FAO/WHO standard limit for irrigation water except higher values of COD, BOD and TSS, which were present much above the acceptable limits. E-coli were found present in all samples. Total coliforms and faecal coliforms were found in very high concentration than the standard limit. The treatment of raw sewage waste water is necessary otherwise the entry of this polluted water in ground water shall be highly harmful to the flora and fauna of the region and will affect the human health. Based on the experimental outcomes, it is suggested that quality measures of sewage waste water should be considered while using such water for irrigation.
