      Residents of the upper part of Nizhny Novgorod have again begun to complain about a foul odor. According to them, the unpleasant smell appeared yesterday at lunchtime in the areas of Rodionova Street, Kazan Highway, the Zhar-Ptitsa shopping center and in Afonino.

      The smell of sewage bothered residents during the night as well as on the morning of 29 December.

      "Again it smells of the treatment plant in Verkhnie Pechery. The smell is so strong you can't open the windows," a local resident noted.

      "At first I didn't understand where the smell was coming from. I walked around the apartment, looking for the source. But then I saw posts on social media with complaints, and everything fell into place," said a resident of the Sovetsky District.

      This year Nizhny Novgorod residents have often complained about unpleasant odors. The long-standing issue was addressed during a live call-in session by the region's governor, Gleb Nikitin. According to him, an "almost detective investigation" was conducted, during which it was established that the source of the stench was the Nizhny Novgorod aeration station. The problem arose because the technological process was accelerated during its reconstruction: the five planned stages of modernization were decided to be carried out in two.

      The first stage is already complete, but to fully eliminate the odor it is necessary for activated sludge to form in the upgraded tanks and for the bacterial maturation process to stabilize. This may take 3–4 months. As part of efforts to combat the smell, air scrubbers with filters were installed and the collectors were sealed. These measures have already had a positive effect — sharp emissions of the stench have ceased.

      The second phase of the station's modernization is planned to begin in 2027 and be completed by 2030. It was previously reported that 11 billion is planned to be allocated to the facility's reconstruction over the next three years.
