Mysore City is an Ancient, historic and one of the beautiful cities of the country. It is the 2^nd largest city in the state of Karnataka, next to Bangalore. It lies about 146km (91 miles) southwest of Bangalore, the capital of Karnataka. The Mysore city is located between 12^o 14’ 41”N to 12^o 22’25” N latitudes and 76^o 34’20”E to 76^o 43’23”E longitude at an altitude of 2526ft above the mean sea level (Map.1). Mysore city Spread across an area of 128.42 km2 (50 sq.miles) & it is lies in the saucer shaped basin & is situated at the base of the Chamundi hills. The City of Mysore in Karnataka is one of the most visited tourist destinations of the state. City is divided into 9 Zones and they sub divided as 65 wards by MCC (Mysore City Corporation) based on 2011 data. The population is about 8, 93,062 in 2011 census, with males 4,46,676 and 4,46,386 females respectively.

In the Study area, the source of water for domestic and industrial purpose is mainly from the Cauvery River and ground water. In recent years industrialization has become main cause of city’s growth. There is diversity in industrial landscape of Mysore with haphazard distribution. The industrial areas are distributed all over the city and its surroundings with lack of order and regulation in industrial location. A large number of small medium and large- scale industries exist in and around the Mysore city, including engineering, chemical, pharmaceutical, food, brewery, distillery, textile, steel and metal smelting. Mysore has adequate water supply resources due to the proximity of Rivers Cauvery and Kapila.

All kinds of variations in wastewater use are possible and it is to be expected that different uses will have different impacts on agricultural productivity, the environment, and human health. Appropriate policy decisions and technical interventions are likely to depend on the nature and characteristics of the wastewater and the way in which it is being used. The following are the three types of waste water use are the most relevant.

There are three sewage treatment plants in Mysuru city Vidyaranyapuram plant is one of them it was started in 1998 and was functioning by bottle bay company Mumbai then after in 2002 it was handed over to the government in south Karnataka Mysuru. Kesare treatment plant was started in 2002, the area is generally formed in a zig zag shape and Rayanakere.

The city has been provided with three wastewater treatment plants. Drainage districts of have the wastewater treatment plant of capacity 60.0 MLD, which is located at Rayankere, H. D. Kote Road, Mysore. The treatment plant for drainage district B is of capacity 67.65 MLD, which is located at sewage Farm, Vidyaranyapuram, Mysore. The treatment plant of the capacity 45.0 MLD, which is located at Kesare Village, Mysore. The wastewater from point source and non-point sources from different areas of the drainage districts are collected in wet wells and treated in the wastewater treatment plants. All the treatment plants have facultative aerated lagoons and sedimentation basins. The process of primary treatment involves simple lagooning and subsequently natural oxidation.

Sampling Stations: The following three sampling stations were selected for the present study located at wastewater treatment plants.

Here Figure 4 this graph represents about the per day untreated and treated water in vidayranyapuram, kesare, Rayankere in the form of MLD (million Liters per day)

This study was mainly emphasis the current status of urban drinking water treatment system in Mysuru for all season the values of physio-chemical parameters are within the limit of water quality standard. In some plants noticed the prolonged equipment errors, but the finished water quality they maintained based on the chlorine dosage. During the monsoon season the values are higher compare to other seasons (winter and summer). The overall conclusion of this study the present operational status of treatment using all three water treatment plants is moderately safe. The existing urban water system full fills the norms but a sustainable point of view can be up graded with newer technologies. Land application of wastewater, sludge and excreta on land is a widespread practice with a long tradition in many countries around the world. Therefore, agricultural use of untreated wastewater has been associated with land application and crop production for centuries. However, over the years, it has become less popular in developed countries with the improvement of treatment technologies and increased awareness of the environmental and health issues associated with the practice.
