Najafgarh drain-sampling and analysis

Over the past years, due to rapid industrialization and advanced agricultural activities environmental deterioration is becoming a major concern. Water is one of the most important and basic natural resource which is being used in industries, agricultural activities as well as for the domestic and commercial purpose. These activities leads to discharge of wastewater, hence, accurate analysis of wastewater is crucial for maintaining the health and safety of the people. Water from all three sectors i.e. domestic, industrial and agriculture contribute into wastewater loads in the Najafgarh Drain in south-west Delhi. For this purpose the south-west Delhi stretch, near Dwarka, of the Najafgarh Drain was chosen to be analyzed for its wastewater quality parameters. On the same stretch of the Drain, treated wastewater from the Najafgarh Wastewater Treatment plant is also disposed. The present study deals with the comparison between the wastewater quality before and after the input of the treated drain water in the Drain. The flow and velocity of the drain water is estimated during the sampling period. The comparative analysis of the quality of wastewater before and after the Najafgarh Wastewater Treatment Facility indicates that there is positive improvement in the quality of water after the input of the treated wastewater, which is expected. These results can provide a basis for further studies and planning of facilities that can aid to solve the problem of deterioration of the natural resources and environment.
