Wastewater collection system

Vilniaus vandenys operates 1,729 km of wastewater networks and 258 wastewater pumping stations in the city of Vilnius and the Vilnius, Šalčininkai and Švenčionys districts.

In most of the service area, domestic wastewater and stormwater are collected through separate systems. In central Vilnius, the Old Town, and parts of Antakalnis and Naujamiestis, a combined sewer system is still in use, carrying both domestic wastewater and stormwater.

From wastewater to renewable energy

Wastewater treatment not only helps protect the environment, but also enables more efficient use of resources.

At the Vilnius wastewater treatment plant, biogas is produced from the sludge generated during the treatment process. This biogas is used to generate electricity and heat. Around 25% of all electricity required by the company is generated from biogas.

In this way, circular economy principles help reduce the use of fossil fuels and return resources generated during wastewater treatment back into the resource cycle.
