Case STORIES

Non-revenue water management in Bulgaria

Surrounded by sprawling parkland, Sofia, the capital and largest city of the Republic of Bulgaria, is located at the base of the popular ski mountain, Vitosha, in the western part of the country. The city has 1.4 million inhabitants. Being in the centre of the Balkan peninsula, it is midway between the Black Sea and the Adriatic Sea and closest to the Aegean Sea.

AVK has been the sole supplier of gate valves for Sofia Water for 20 years, and in the meantime also the main supplier of butterfly valves. As a result of the city’s investments, the regulation of the drinking water networks in Sofia has become much more stable, flexible and comfortable for the customers. In case of repair or rehabilitation works in the networks, smaller areas can now be closed and isolated from the rest of the networks thus affecting much fewer households. Besides water losses caused by emptying and refilling the water networks before and after, the repair works have been reduced significantly as well.
