The water in Sofia travels two years until it reaches the taps in our homes

Sofiyska Voda, operated by Veolia, has participated in several educational initiatives celebrating the World Water Day, held on March 22.

  • "Valuing water" is this year’s theme of the World Water Day under the patronage of the United Nations
  • Sofiyska Voda, operated by Veolia, and the Center of Competence "Clean and Circle" have organized a meeting – discussion dedicated to the scientific solutions for water preservation
  • The children’s scientific center Muzeiko told an interactive story to the kids about the water cycle and how significant water is

The water entering the Iskar Dam needs at least 2-3 years to pass from the dam and continue to the potable water treatment plants before reaching the taps of the citizens of Sofia. This and a lot more interesting facts and innovative solutions for water preservation were revealed at a scientific discussion which Sofiyska Voda, operated by Veolia, together with the Center of Competence "Clean&Circle" organized on the occasion of the World Water Day – March 22.

Scientists from leading universities in the country and practitioners from the WSS operator presented different scientific challenges and modern practical solutions for the preservation of the essential resource. The discussion with topic "Five Scientific Solutions for Water" was conducted online on 23 March 2021, and you can watch it here.

Researchers from Sofia University presented the results of their work over innovative clean water technologies, and researchers from UACEG summarized the practical benefits of implementing circular solutions in the WSS systems, as a result of a conducted large-scale analysis. Sofiyska Voda, operated by Veolia, shared details about two advanced technologies it has implemented over the last year in the potable and wastewater treatment processes.

On 22nd March 2021 the young researchers were able to learn live on the Facebook page of Muzeiko children’s scientific center about the route of water as well as interesting facts about water – e.g. how it appeared on Earth, how much water do people need, the amount of liquid that camels can drink at a time, etc. You can watch the video here.


This year the UN marks the World Water Day under the motto “Valuing Water” to remind that still more than 2.2 billion people, or nearly 29% of the population on Earth, do not have access to safe potable water. As per data in the latest report on water of the organization, the effective use of water has increased only by 4% since 2015. The World Water Day has been celebrated by the United Nations since 1992 and the goal is to draw the attention to the value of the water resource and the need to preserve it.
