Accidents occurring on forest sites, leakage of oil products during refueling and operation of forestry equipment, lead to long-term point impact on soil and water in places where equipment and fuel and lubricants warehouses are concentrated. Long-term use of the logging site leads to intensive exploitation of forest areas and roads, contributing to oil pollution of water bodies through the water protection zones of which they pass. In places where oil products leak, it is necessary to organize the treatment of surface runoff, which washes away pollution from the surface of the sites, using local treatment systems, in which combined natural sorption materials act as a treatment agent. The features of the arrangement of cleaning systems on forest sites and roads are revealed: the conditions of swampy and water-saturated forest areas, the most typical in the North-West of Russia, the lack of power supply, the inability to bury structures due to a small difference in elevations between the roadbed and the adjacent terrain or water level, taking into account soil cover and sand removal - the need to install a sand trap device with a power reserve, the performance of the facilities is selected according to the amount of wastewater flow, designed for shorter catchment areas, ensuring the reception of wastewater with a flow rate of 0.3 - 3.0 l / s. Features of the dry state of loading of local treatment facilities not flooded with water make it possible to increase the efficiency of wastewater treatment from oil products by an order of magnitude by increasing its capacity. The use of three types of sorbents with different sorption kinetics allows the most complete use of the filter capacity up to breakthroughs of oil products during cleaning.
