Abstract. Wastewater is the result of many human activities, and its volume is growing more and more every year. Usually the issue of wastewater treatment is solved in municipal wastewater treatment plants. These facilities have been operated in our country for many years, the degree of their consumption is very high, it is more than 60%, and this has a bad effect on the environment. Poor quality of wastewater treatment leads to problems such as degradation of aquatic ecosystems and various diseases that will be transmitted by water from contaminated sources, Wells, freshwater wells. The Problem is significant not only in our country, but all over the world. For example, according to a UN World Report, the amount of wastewater transported worldwide, with the exception of highly developed countries (to which Kazakhstan does not yet belong), their total pollution is growing at a steady pace. At the same time, as noted in the article, the amount of wastewater is discharged into the environment without proper treatment [1]. In our Republic of Kazakhstan, the first urban wastewater treatment plants appeared in the 1950s.In the 20th century, at a time when mechanical sewage treatment plants (MOS) were built and put into operation in large cities. Urban wastewater was discharged into filtration fields or water tanks without adequate treatment. Currently, there are many used sewers. Consumption was over 90%. In our city of Taraz, there is absolutely no scythe, urban outflows through temporary wells are immediately discharged to filter fields, this was in 2010. During this time, the picture has not changed. Urban sewerage is associated not only with residential buildings, but also with industrial plants. This causes an excessive hydraulic load on filtration zones that pollute groundwater. City leaders promised to solve this problem 10 years ago, but the problem still exists and is current.
