Abstract: Each industrial enterprise has an environmental risk associated with the discharge of untreated or insuffi-ciently treated wastewater. In such cases, the probability of wastewater discharge without treatment is maxi-mum. The problem of wastewater treatment during construction on the site, shaft sinking and land development of open-pit mines remains unsolved due to the high cost and commissioning dates of major treatment facilities. A concept of wastewater treatment facilities with the use of soft shell structure (geotubes) was proposed. The use of modern sorbents as a filter material in the geotube allows to effectively purify wastewater and reduce the concentration of pollution to the permissible values. The environmental risk reduction in the application of geotubes was assessed quantitatively by mass of discharged pollutants. Application of geotubes allows to reduce discharges, in one of the cases, by 11 tons. In addition, a cost-effectiveness assessment of geotubes used for wastewater treatment during the construction of major wastewater treatment facilities was carried out. Reduction of fee for discharge of effluents into water bodies reaches 86%. Also, the rapid pace of construction of sewage treatment plants on the basis of the geotubes helps to reduce the environmental risk. This is largely due to the lack of administrative barriers in the form of a building permit.
