A pipe burst during hydraulic testing in the Kalininsky district of St. Petersburg on June 4th, resulting in a powerful water fountain that reached the height of a nine-story building and damaged a parked car.

The incident occurred on Cherkasov Street when a pipe ruptured during planned hydraulic tests conducted by JSC “TEC St. Petersburg.” The leak, involving a heat carrier with a temperature of up to 40°C, was reported at 13:33 and contained by 14:25.

The force of the water jet caused significant damage to a nearby parked car, blowing out its windows and causing stones to fall onto the roof.

According to a witness, the fountain produced slight evaporation, but not steam. Emergency services from TEC were observed at the site of the rupture.

JSC “TEC St. Petersburg” stated that the hydraulic tests are conducted to identify worn-out sections of pipes before the heating season begins, helping to prevent more serious accidents. The damaged section of the pipe will be included in the repair plan following the completion of the tests.
