The maintenance will cause a temporary suspension of hot water services across numerous residential neighborhoods and significant institutions, including the Lozenets University Hospital, the U.S. Embassy, and the Sofia Zoo. Concurrently, the utility provider established a deadline of August 31 for customers to submit objections regarding annual heating and hot water settlement bills.
