On March 23rd, a solemn ceremony with the Governor of St. Petersburg Alexander Beglov participation was held to complete the Okhta collector first stage construction. The event is the city environmental milestone. This project enabled Vodokanal to raise the municipal wastewater treatment level up to 99.5%. The ceremony coincided with several significant regional events - the “Ecology of Big City” and “Baltic Sea Day” forums.

The event was also attended by Roman Minukhin, Director of the Department of State Policy and Regulation in the Field of Water Resources, Environmental Economics and Federal Property Management of the Ministry of Natural Resources and Environment of the Russian Federation, Sergey Dregval, Vice Governor of St.Petersburg, and other guests of honor.

The project scope provided rechanneling of 19 direct discharges and eliminated annual discharge of about 4.3 million cubic meters of untreated wastewater into the Okhta River. As of today, wastewater is and will be directed to the Northern Wastewater Treatment Plant for a full cycle of mechanical and chemical-biological treatment, including the nutrients (nitrogen and phosphorus) removal.

Alexander Beglov noted that the collector commissioning will bring the level of wastewater treatment in St. Petersburg to a record-breaking 99.5%, which will become our city’s another step towards becoming one of the world cleanest and in fulfillment of the Helsinki Commission for the Baltic Sea Marine Environment Protection recommendations.
