A new administrative contract has been signed with the city for the period 01/12/2022–30/01/2032.

The Tallinna Vesi Group consists of the parent company AS Tallinna Vesi and its subsidiaries Watercom OÜ and ASTV Green Energy OÜ.

Watercom, a subsidiary established in 2010, aims to provide services to the parent company, expand the range of services offered and develop non-regulated services. The subsidiary Watercom OÜ is wholly owned by AS Tallinna Vesi and its results are consolidated in the group's results.

Tallinna Vesi also owns a 100% stake in the subsidiary ASTV Green Energy OÜ (established in 2021), which has a longer-term goal to offer reusable resources generated from the provision of water services as products in the green energy market. 

The structure of the group has remained largely unchanged in recent years.
