Physico-chemical Parameters Study of Sewage From Open Sewerage System of Urban Areas of Aurangabad City

Rapid urbanization is observing in India. The urbanization results in some environmental problems, such as water resource pollution due to disposal of sewage or wastewater. To reduce the intensity of such problems the efficient utilization of water resources is necessary and which may maintain the quality of water resources. The present investigation deals with sewage characterization to know the parameters of sewage generated in Aurangabad city, to assess existing pollution load in sewage system and to predict needed to adopt proper sewage treatment system for balance and better healthy environment in urban areas. The sewage samples were collected from various places of the Aurangabad city during the months of April and November, 2013. The pH and temperature were analyzed at the sampling sites and other parameters, namely turbidity, total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), dissolved oxygen (DO), chlorides, chemical oxygen demand (COD), biological oxygen demand (BOD), total hardness, nitrate, sulphate and phosphate were determined as a quality indicating parameters. The pre-monsoon quality study of sewage shows higher values to most of the parameters when compared with post-monsoon season’s quality parameters. In the post-monsoon season pollutants load in the sewage was found within permissible standard limits given by Central Pollution Control Board (CPCB), India.
