19.09.2025. Moscow Region Governor Andrey Vorobyov assesses the progress of wastewater treatment plant construction in Solnechnogorsk

VIS Group is completing the construction of a modern wastewater treatment facility in the village of Osipovo in the Solnechnogorsk urban district. The treatment facility has been built on a site covering almost 190,000 m2 using modern technologies. The capacity of the modernized facility will be 27,000 m3/day, with a maximum capacity of 1,744 m3/hour. Today, Moscow Region Governor Andrey Vorobyov reviewed the project's progress.

VIS Group representatives briefed the regional governor on the final stage of the project. The facility’s construction readiness is 95%, with 138 people employed on-site. Hydraulic testing of the primary and secondary settling tanks has been completed. During the testing, the equipment was subjected to pressures 1.5 times greater than the operating pressure. This stage is a key one in the process of commissioning utility systems, as it enables the timely identification of potential problems. Testing revealed no deviations from the norm, confirming the reliability of the installed equipment.

Builders have begun testing aeration tanks—specialized reservoirs where wastewater will undergo treatment. Meanwhile, installation of process equipment, heating and ventilation systems for the post-treatment building, and finishing work on the administrative and amenity complex are underway.

“The large wastewater treatment facilities in Solnechnogorsk are designed to serve approximately 70,000 people. Their construction is being carried out with federal funding under the president's national project. Equipment commissioning and hydraulic testing are currently ongoing. The treatment facilities are expected to be fully operational by the end of the year,” noted the governor of the region.

The reconstruction of the wastewater treatment facilities is being carried out by VIS Group under a government contract. This is one of the holding’s several projects being implemented in the Moscow Region.

“VIS Group's presence in the Moscow region is growing. We have created a strong production base here, anchored by road projects. The largest of these is the concession for the construction of the Mytishchi High-Speed Chord, which is currently in operation. The region is a priority, and we are ready to apply our expertise and investment resources to new projects focused on modernizing and creating infrastructure that improves people's lives and facilitates the region's intensive socio-economic development,” noted Sergey Yudin, CEO of VIS Group.

The Osipovo complex is part of a large-scale program to upgrade the Moscow region's public infrastructure and is included in the national “Environmental Well-Being” project and the federal “Volga Recovery” project. This project, which is being implemented in several Russian regions, aims to improve the environmental condition of Europe's longest river by reducing the discharge of polluted wastewater by three times.
