Sochi Sea Water Quality Meets Standards

Chemical and bacteriological tests are conducted at all stages of purification. Specialists from an accredited laboratory also monitor the quality of seawater in the area of deep-sea outfalls of the "Adler," "Kudepsta," "Bzugu," "Dagomys," "Magadan," and "Lazarevskoye" sewage treatment plants.

A multi-stage wastewater treatment system has been implemented at these facilities. Eight indicators are examined. Over 15,300 analyses for pollutants in wastewater have been carried out in the first three months of 2025. All of them are within the normal range, and no concentration excesses have been recorded. "In total, Sochi's treatment facilities currently receive 168,000 cubic meters of wastewater per day.

By the beginning of the summer season, when the load on the communal infrastructure will significantly increase, quality control of wastewater treatment will be strengthened at all facilities," noted the Acting Director of the Department of Urban Economy of the Sochi City Administration, Evgeny Shelkovnikov. The technical condition of all deep-sea outfalls of treated wastewater into the Black Sea, the total length of which exceeds 10 kilometers, is checked annually with the involvement of divers. The resort has also intensified efforts to identify and prevent illegal connections to the city's centralized wastewater and water supply systems, as well as cases of untreated discharge onto the terrain.
