Residents of the Lyulin district in Sofia, Bulgaria, will experience a week-long disruption of hot water service from June 15th to June 21st. The outage is due to scheduled annual maintenance on the district heating network, according to Toplofikatsiya Sofia, the city’s heating utility. The repairs involve the replacement of a section of the main heating pipeline serving micro-districts 4 and 5 within Lyulin. This planned work aims to ensure the reliable operation of the heating system during the upcoming winter season. Authorities have not specified the potential impact on local businesses or vulnerable populations. The utility company has advised residents to prepare for the interruption in service.
