Health authorities in Ekaterinburg have legalized yellowish tap water for residents after raising the allowed iron concentration in municipal supplies until the end of 2032.
The decision by the Sverdlovsk Oblast branch of consumer watchdog Rospotrebnadzor means a yellow hue in household water is no longer treated as an official deviation, according to regional news portal Ura.ru. Under the new temporary standards, local utility companies are permitted to supply tap water containing up to 0.42 milligrams of iron per unit, an increase from the previous limit of 0.3 milligrams.
Resource supply company T Plus stated that the higher iron thresholds and color standards would not harm overall water quality, assuring residents that tap water will remain suitable for domestic needs and meet all sanitary requirements. The regional Center for Hygiene and Epidemiology also confirmed that its health evaluation identified no safety risks for the local population.
Ekaterinburg is the fourth-largest city in Russia and the administrative center of Sverdlovsk Oblast, situated in the Ural Mountains region. Rospotrebnadzor serves as Russia's federal agency for sanitary supervision and consumer rights protection. T Plus is one of the largest private utility and energy companies in the country, managing municipal heating and water distribution systems across multiple Russian regions.
Filter failures and September pipe damage
The regulatory change follows widespread water service disruptions across Ekaterinburg recorded in early August and early September. During the summer, deteriorating raw water quality obliged the local water utility, Vodokanal, to increase its use of chemical reagents. That extra chemical treatment caused filter failures at the central filtration station, while separate supply cutoffs in September were explained by authorities as stemming from physical damage along Vodokanal pipe networks.
Similar water problems in Leningrad Oblast
Tap water quality issues have also sparked public complaints elsewhere in Russia. Residents in the Kirovsky District of Leningrad Oblast reported that their municipal tap water turned yellow, felt greasy to the touch, and developed a foul odor. In response, regional operator Lenoblvodokanal promised to replace the filtering material at its water intake facility.
Leningrad Oblast is a federal subject located in northwestern Russia, entirely surrounding the city of Saint Petersburg. As water utility providers across Russian regions address aging infrastructure and seasonal contamination, the temporary water standards in Ekaterinburg will stay in effect for the next six years, expiring in December 2032.
