Impact Assessment of Waste Water Streams on Water Quality of River Pavana in Pimpri Chinchwad City Area

Abstract

Present research work was done for 23.2 Km stretch of river Pavana from Kiwale to Dapodi in District Pune, Maharashtra. In this research, discharge measurement was done for 19 waste water streams in Pimpri Chinchwad city area. These waste water streams are continuously disposing untreated waste water in River Pavana. Total pollutional load was calculated by using characteristic values such as Biochemical Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids along with the discharge measurement of waste water stream. Area velocity method was adopted for measurement of waste water stream discharge. BODmix and Degree of Treatment required were calculated for River Pavana. BODmix of river water of River Pavana (stretch from Ravet to Dapodi) was compared with raw water quality standards.
