In 2023, Traveter Grupp OÜ renovated the gate valve chamber of the Paunküla reservoir. The work included installing and dismantling platforms and removing loose and disintegrated concrete and plaster from the floor and walls. During the works, water leaks were sealed, the bottom of the chamber was concreted with waterproof concrete, and pipe penetrations and wall-to-floor joints were sealed. Reinforcing mesh was installed on the chamber walls, which were then shotcreted with waterproof shotcrete.

Materials were supplied by Primostar OÜ
