Looking to the severe condition of the sewerage system, it was decided to carry out a study to analyze the effect of open drainage system on water quality of Chambal River. To do this work, initially samples of wastewater were collected from different open drains as well as from Chambal river of Kota city and then samples were tested for various physic-chemical and biological parameters. The observed results were compared with permissible limits prescribed by the Indian Standards. From comparison, it is concluded that the parameters are beyond the permissible limits. The direct discharging of open drains in the river is creating an alarming situation to the quality of the water of Chambal River, which is the main source of drinking water for Kota city and other districts of Rajasthan. Key Words: Physico-chemical parameters, biological parameters, wastewater, sewerage system, Chambal River, open drains 1. INTRODUCTION The only perennial river of Rajasthan ǮThe Chambalǯ is the main source of Kota city as well as the district for the purpose of drinking water, agriculture, and various other uses. The river Chambal flows through the Kota city, an educational and industrial city of Rajasthan. Water of Chambal River is getting contaminated in the area because of various polluted activities and population increase. There are 26 open drains situated in Kota city which are directly falling in the Chambal River due to reason that the sewerage system of Kota city is at present not developed to handle and treat the wastewater generated daily. The sewage treatment plants installed in the city have a capacity of only 50 MLD against the requirement of 312 MLD for present population. So the objective of this study is to carry out an analysis of sewerage system of Kota and to know about the effect of wastewater from open drains on the water quality of Chambal River. 1.1 Aims and Objectives The aims and objectives of the study are as follows: 1. To study the parameters of wastewater of open drains. 2. To evaluate the effect on the quality river water due to the falling of open drains. 3. To know about the sewerage system of Kota. 4. To study that whether the demand of STPs in Kota is fulfilled or not. 2. MATERIALS AND METHODS 2.1 Study Area The city of Kota is situated along the eastern bank of river Chambal in southern part of Rajasthan. It is the third largest city of Rajasthan after Jaipur and Jodhpur respectively. The geographical coordinates of Kota are 25.18° N 75.83°E. It extends over an area of 12,436 km2 which amounts to about 3.63 % of the total land covered by Rajasthan. The average elevation of Kota is 271 meters. The district is bound by Sawai Madhopur, Tonk and the Bundi districts, to its north and North West. The river Chambal separates these districts from Kota, and forms a natural border line. The district of Kota is famous for sand stone, Kota stone, Kota Sarees, delicious kachori, and famous coaching centers. 2.2 Plan, Sampling and Collection It is known from newspapers and electronic media that the quality of river water is getting deteriorated continuously by discharging of untreated water. Also in the study of researchers, it is explained that the quality of river water is adversely affected by direct discharging of waste water and also it is affected by lack of sewerage system. On this basis different theories from different research papers have been studied in the first two months of the study period. Based on these theories, it is decided to study and analysis of sewerage system and water quality of open drains falling in Chambal River. To carry out this task, first of all, proper information was collected be require about the existing system of sewerage, sewage treatment plants and open
