The branch "Minsk Heating Networks" of RUE "Minskenergo" informed residents of the Leninsky, Zavodsky, Sovetsky, and Pervomaysky districts of Minsk that from November 16, 2026, and until the end of the heating season, a special food dye — fluorescein — will be added to the network water of heating pipelines.

If you notice that the water from the tap has changed color and turned greenish, there's no need to panic, as everything is under control and it was planned that way.
The water is being dyed in order to more quickly detect leaks and unauthorized use of the coolant, as well as to check the tightness of water heaters.
Specialists assure that fluorescein is absolutely safe for human health and the environment. Its use is permitted by the Ministry of Health in accordance with the requirements of sanitary and epidemiological supervision.
