Tallinna Vesi will build and renovate 40 kilometres of pipelines this year

The construction and renovation of Tallinn’s water supply, wastewater and stormwater pipelines have taken place on a record scale in recent years and will continue at the same pace this year. This year, Tallinna Vesi’s major construction projects include the development of new stormwater systems, which will help reduce the risk of flooding in different parts of the city.

“The goal this year is to build and renovate 40 kilometres of water supply, wastewater and stormwater pipelines in Tallinn, helping to ensure the reliability and long service life of the city’s infrastructure,” said Marti Vaksmann, Head of Pipeline Planning and Construction at Tallinna Vesi. According to him, at least 25% of the renovation and construction works will be carried out using trenchless methods in order to minimise disruption to traffic and everyday urban life.

Several important stormwater management projects will continue this year. “The construction of separate sewer systems helps the city cope better with intense rainfall and ensures the functioning of the urban environment even during heavy rain. In addition, it prevents the mixing of domestic wastewater with stormwater, as stormwater is directed into a separate pipeline system, which in turn reduces the load on the wastewater treatment plant,” Vaksmann added.

The works are being carried out in cooperation with the City of Tallinn, Utilitas and other utility network operators to minimise traffic disruptions caused by construction activities.

Major ongoing projects

Work is already underway in several districts. In the city centre, Lauteri Street is being reconstructed in cooperation with the City of Tallinn and Utilitas. In early March, construction began on a new stormwater retention basin in the area of A. Laikmaa Street, Maakri Street and Rävala Boulevard.

“The Maakri area is a good example of why these investments are necessary — recurring flooding has occurred there, and the new stormwater retention basin will help alleviate the problem,” Vaksmann explained.

In North Tallinn, a stormwater settling pond is being built near the intersection of Lahepea Street and Kolde Avenue to help reduce flooding in the area.

Pipelines on Paljassaare Street and Paljassaare põik Street are also being renovated in cooperation with Utilitas. Construction works on Peterburi Road are taking place in cooperation with the City of Tallinn and Rail Baltica.

Major upcoming projects

In North Tallinn, construction will begin on a strategic stormwater outflow corridor on Sõle Street (between Kolde and Kaera streets) and on Auna Street (between Aru and Sõle streets). The works will continue next year on Kolde Avenue (between Ehte and Sõle streets).

One of the largest projects of the year is also located in the same area: large stormwater pipelines will be installed on Paldiski Road between Merelahe Road and Mooni Street in cooperation with the Hippodrome development project and Utilitas, in order to reduce flood risk in the area. The works will begin in May and continue in stages until the second half of 2027. Since the construction will also affect traffic, detailed traffic arrangements will be published separately before the works begin.

Near the city centre, major works are planned on Keldrimäe Street as well as Raua and Kreutzwaldi streets, where pipelines will be built to serve the new television building — both projects will be carried out in cooperation with Utilitas.

In Mustamäe, renovation of pipelines on A. H. Tammsaare Road between Sõpruse Avenue and Mustamäe Road began yesterday, on 9 March. Where possible, trenchless methods will also be used along the edge of the roadway. Reconstruction works are being carried out in the inner квартals of the Sütiste Street and Sõpruse Avenue area, with minimal impact on traffic.
