India is the biggest and the oldest irrigating country in the world and most of the provinces depend mainly on agriculture. Water is essential. Day by day population is increasing at alarming rate; there would be very heavy demand for water supply for domestic, irrigation, and industrial needs. Water pollution is one of the important aspects of environmental studies, which needs a greater emphasis because of its wide spread nature. People are attracted towards cash crops like sugarcane, tomato, and vegetables. Increase in population causes increase in unemployment. There will be more land demand for cash crops, which increases requirement of water. Wastewater is discharged in water bodies like natural stream, nalla, river, lake, pond or marine coastal areas with treatment or without treatment. The volume of wastewater generated by domestic, industrial and commercial sources has increased with population, urbanization, improved living conditions, and economic development. The productive use of wastewater has also increased, as millions of small-scale farmers in urban and peri-urban areas of developing countries depend on wastewater or wastewater polluted water sources to irrigate high-value edible crops for urban markets, often as they have no alternative sources of irrigation water.There will be more land demand for cash crop, which increases requirement of water. On the contrary, increased population will utilize water 100 Lpcd in urban area and 50 Lpcd in rural area. Out of that 80% water will be converted into sewage. Regarding with this , I have undertaken this paper, “ Reutilization of Treated Wastewater of Shrigonda City for Irrigation. ” for this purpose, I have selected the Saraswati river in Shrigonda City from its Origin for analysis purpose and I have collected and analysed the physical and chemical characteristics of water samples along the Saraswati river at six selected stations. This data represents quality of water from of Saraswati River all along the length. From this I have concluded that the quality of water is degrading at all respective stations for the whole length. In this paper I have discussed about the waste water of Saraswati River in Shrigonda City can be reutilized for irrigation purpose with a little treatment instead of direct use to avoid any harmful effects at the farmers end. Benefits obtain by using waste water for agriculture. Thus Saraswati river water will be an alternative source of water for irrigation, with a little treatment considerations, along the length of river in the irrigation period.
