3.3 Highlights of the year
INVESTMENT OF THE PAST DECADE
In 2020, we commenced the reconstruction of
the mechanical treatment stage at
Paljassaare Wastewater Treatment Plant.
With a total cost of €7.6 million, it is the largest
investment of the past decade for Tallinna
Vesi. We are renovating the very first part of
the wastewater treatment plant, i.e. the
treatment stage, which removes larger
debris, sand and grease from the wastewater.
This major project is ahead of schedule and
will continue throughout 2021.
LARGE PROJECTS ON WATER AND
SEWER NETWORK
In 2020, we renovated 4.7 kilometres of water
pipes and 3.8 kilometres of sewers and
worked on several major projects. In order to
enhance the reliability of water supply service,
the largest work took place in the area of
Punane Street in Lasnamäe, where we
reconstructed the water main supplying more
than 100,000 inhabitants in Tallinn and
Maardu.
We renovated part of the water main on
Järvevana Road, thus improving the security
of water supply in the Mustamäe and Õismäe
districts of Tallinn. We upgraded the pumping
stations in Pirita-Kose and Northern Tallinn
with new technology and telemetry.
During 2020, we also reconstructed a large
collector at Kadaka Blvd, which directs
wastewater from Saku, Saue, Laagri and
approximately half of the properties in
Nõmme district to Paljassaare Wastewater
Treatment Plant.
The reconstruction project was essential to
ensure continued and uninterrupted service
in these areas in the future. A temporary
pressure line was built as a bridge over the
road to keep the traffic going during the
works, which was the longest overground
pumping line ever to have been constructed in
the Baltic States.
AVAILABILITY OF SAFE TAP WATER
In order to make tap water more accessible
also in public urban space, we maintain 8
public drinking water taps in Tallinn. In 2020,
we started collaboration with the Port of
Tallinn and installed stickers emphasizing the
reliability of tap water at five drinking water
fountains in the Port’s D-terminal.
RAISING ENVIRONMENTAL AWARENESS
In early 2020, we ran an advertising campaign
"Mythbusters" on television, in social media
and cinemas, aimed at illustrating in a
humorous way how much work it takes to
treat drinking water and why it is important to
prevent garbage from entering the sewers.
