Tallinna Vesi’s fourth-quarter sales reached €18.9 million

The sales of AS Tallinna Vesi in the fourth quarter of 2025 were €18.9 million, up by 5.9% compared to the same period last year. Growth in revenue was mainly affected by price changes related to investments. 

In the fourth quarter, investments amounted to €18.6 million, which is 15.6% more than in the same period of 2024. Aleksandr Timofejev, the CEO of Tallinna Vesi, said that in the fourth quarter the company moved ahead with planned investments and was reassured that its earlier environmental investments had put it on the right track. "The Green Company of the Year award we received at the end of the year shows that we are making an impact and that we are on the right track in investing for the future. When planning investments, we must consider not only future trends and operational continuity, but also the affordability of water services for consumers. At Tallinna Vesi, we are responsible for providing drinking water to about half a million people, as well as ensuring that wastewater is treated in an environmentally friendly way and returned to nature," said Timofejev. In 2025, Tallinna Vesi invested a total of €56 million.

“On the last day of 2025, an exceptional natural event put our crisis plan to the test, but the team quickly resolved the disruptions that occurred. Once again, we apologise that many people in Tallinn had to spend New Year’s Eve stocking up on water, which was otherwise readily available from their taps for all the other 364 days of the year. The water supply was restored to all consumption points during New Year’s Eve. We are analysing technologies to mitigate the impact of similar natural events and improve customer service based on this experience," said Aleksandr Timofejev.

The quality of drinking water remained excellent throughout the fourth quarter, meeting 99.9% of all quality requirements. During the quarter, the company took 1,019 water samples. According to Timofejev, clean tap water is ensured by an efficient water treatment process, regular monitoring of the water distribution network and ongoing preventive maintenance activities, as well as timely investment. Revenue from the sale of water services increased by 7.3% year-on-year, or €1.11 million, to €16.33 million. Revenues from the sale of water services decreased for water services to business customers and increased for water services to private customers. The change in the sales of water services was mainly due to the new prices for water services introduced on 1 May. These prices took into account both the legal obligation to harmonise prices for private and business customers by 1 July 2026, and the need for investment to ensure the sustainability of water services.

Tallinna Vesi’s annual return on assets was 4.2%. The company’s net profit for the fourth quarter of 2025 was €4.51 million, which is an increase of €0.36 million compared to the same period the previous year. The growth in net profit has been driven by operational efficiency and the justified return on investments made to ensure a clean environment and service continuity.

“The services provided by our subsidiary Watercom and the successful start-up of the cogeneration plant, which produced 100% of the heat and 59% of the electricity needed for wastewater treatment, made a significant contribution to the company’s financial results,” explained Aleksander Timofejev. The effective management of treatment processes also had a positive effect on this result.

Tallinna Vesi aims to provide an excellent customer experience, future-proof its infrastructure and ensure the continuity of the vital service it provides, all the while keeping the price for the service affordable for consumers.

At the water treatment plant, activities related to the reconstruction of the osonation stage and the procurement of the new building design are ongoing.

In wastewater treatment, the installation of primary and secondary screens in the mechanical treatment, upgrading of the biological treatment, reconstruction of the sludge treatment, and renovation of the secondary clarifiers have been completed. Investments in the wastewater treatment plant amounted to €15.3 million in 2025.

By the end of the fourth quarter, we had rehabilitated and constructed 45.1 kilometres of pipes. Almost half of these, or 22 kilometres, were built using environmentally friendly no-dig methods. We are working closely with the City of Tallinn and other partners so that we can complete as much work as possible at the same time.

In the fourth quarter, major pipe construction work was carried out on Kolde Avenue as part of the development of a strategic stormwater receiving system for the North Tallinn area, on Peterburi Road in cooperation with the City of Tallinn, and on Retke Road in cooperation with Utilitas. Pipe construction also continued on Paljassaare Road. Construction of the Nõlvaku collector is in its final stages, with the final works to upgrade ventilation systems underway. Work started on the reconstruction of water and sewer pipes in Lauteri Street and at the intersection of Endla and Tehnika streets. The renovation of the water pipes on Bornhöhe Road, as well as the construction work in Tuukri and Uus-Sadama streets as part of the extension to the stormwater collector starting from Reidi Road, has been completed. In cooperation with the City of Tallinn and Utilitas, the renovation of Värvi and Mustjõe streets was completed.

A stormwater scheme is being developed for the Mustamäe area. The scheme uses nature-based solutions to ensure longer retention times for stormwater and create a greener urban environment. These stormwater solutions help to reduce the risk of flooding during periods of heavy rainfall.

In the fourth quarter, the quality of treated effluent from the Paljassaare wastewater treatment plant outperformed the effluent standards. To keep the Baltic Sea clean, the company uses efficient treatment processes that helped to remove approximately 326 tonnes of solid waste, 55 tonnes of grit, 511 tonnes of nitrogen and 64 tonnes of phosphorus from wastewater during the fourth quarter of 2025.

The water loss rate in the water distribution network fell to 11.87% in the fourth quarter from 12.67% a year earlier. In order to keep water loss rates low, the company carries out continuous online monitoring of the water distribution network and continues with its planned water network rehabilitation programme.

By the end of the fourth quarter of 2025, Tallinna Vesi had installed smart meters for more than 80 per cent of its customers, with the project due to be completed in 2026. The new meters provide information on water consumption, allowing leaks in customers’ pipes to be detected as early as possible. This will help to protect the environment and minimise the risk of property damage caused by water accidents. The switch to smart meters has received very positive feedback from customers, and the meters provide the water company with a clear picture of water consumption in the service area.

As a vital service provider, Tallinna Vesi recognises the importance of raising consumer awareness of the benefits of fresh tap water and of environmental protection. In the fourth quarter, we took part in the Impact Day sustainability festival, and opened the doors of the water treatment plant to the public as part of the Open House Tallinn architecture event.

We were awarded the title of Green Company of the Year at the Estonian Successful Companies Awards. The Estonian Waterworks Association recognised two of our employees and named our cogeneration plant the Water Achievement of the Year.
