The main purpose of the Sengileevsky reservoir is currently the flow part accumulation of the Nevinnomyssky canal for municipal and industrial water supply of the city of Stavropol, the city of Mikhailovsk, Shpakovsky and Grachevsky districts, the irrigation of the river Egorlyk and the water supply regulation in the Rostov region and the Republic of Kalmykia, provision of water to the Right-Egorlyk Canal, Mezhdurechenskaya Environmental Protection Agency and incidentally, Egorlykskaya and Novotroitskaya Hydroelectric Power Station, Stavropol CPP. From the Sengileev reservoir water is supplied to the city of Stavropol and several other districts of the region, with more than 1 million people being provided with water. Water intake structures with a pumping station on the Sengileev reservoir are unique and have no analogues in Russia. Water is taken by pumps from a depth of 10 meters and then supplied by three pumping stations to a height of about 500 meters. The water quality in the reservoir in different years mainly corresponds to classes II – III, “pure” or “moderately polluted” with a WPI close to 1, whereas in the tributaries for a number of sections the water quality may decline in certain periods to V-VI as “Dirty” and “extremely dirty”. The main idea of the work is to use an environmentally safe technology to combat drainage, pre-purification of water in front of the sewage treatment plant and ensuring uninterrupted water supply in settlements at any time of the year.
