Stockholms Stadshus AB is adjusting its guidelines for how subsidiary companies should handle major investments exceeding 300 million SEK or those of strategic importance. These changes, effective January 1, 2026, include clearer rules for calculating future cost increases (inflation/index) in project budgets. The aim is to strengthen and clarify the governance of the city's large investment projects.

Stockholm Vatten och Avfall (SVOA) has been tasked with improving the water quality in Stockholm's lakes and rivers by reducing phosphorus and copper emissions from stormwater and wastewater. While SVOA met its targets in 2025, the work continues with new treatment facilities and measures against misconnected pipes to achieve good water status by 2035.

The Stockholm City Council will decide on an action program for Strömmen to improve water quality and the habitat for animals and plants. Strömmen currently has poor ecological and chemical status due to pollution from, among other things, port areas, traffic, and wastewater. The measures, which are estimated to cost hundreds of millions of kronor, include cleaning up bottom sediment and stormwater, as well as improving the physical habitat.

This report from Stockholm Vatten AB details the status of 43 major investment projects exceeding 200 million SEK each, with a total projected cost of nearly 37 billion SEK.

The report outlines progress, timelines, and any cost deviations for each project, including climate adaptation measures and new water reservoirs.

The board of Stockholm Vatten AB has approved a report detailing procurement decisions made in the second half of 2025 for contracts exceeding 10 million SEK. These decisions cover essential services for the city's water and waste management, including maintenance of vacuum waste systems in Hagastaden and Kista Norra, purification of water reservoirs, renovation of water pipes in Ålsten, and service of sewage pipes and odor reducers. The CEO made these decisions after consultation with the procurement council, and they are now being reported to the board.

Stockholm Vatten AB has approved a list of investment decisions, ranging from 10 to 50 million SEK, made by the CEO between July and December 2025. These investments cover various projects, including ventilation upgrades at Norsborg waterworks, replacing deteriorating water and sewer lines in Nälsta, and crucial connections to the new sewer tunnel at several locations across the city. The approved investments also include water and sewer work for new housing developments in several areas and improvements to existing networks in Birkastan-Röda Bergen and Nybrogatan.

Stockholm's Future Wastewater Treatment (SFA) is a major project to close the Bromma treatment plant and redirect its wastewater to the Henriksdal treatment plant, which is being expanded and modernized to meet new environmental requirements and accommodate a growing population. The project, budgeted at approximately 22.5 billion Swedish kronor, is expected to be fully completed by 2031. Despite previous delays and cost increases due to market conditions and complex work, the project is proceeding according to its revised schedule and budget.

Stockholm Vatten AB will appoint Sigrid De Geyter as its representative at the annual general meeting of the Mälaren Water Conservation Association on May 5, 2026. The association, a non-profit organization, works to improve the decision-making basis for urban planning and other activities that affect water conditions in Lake Mälaren.

Stockholm Vatten AB will appoint representatives to the Tyresåns Water Management Association, an organization dedicated to preserving and developing the natural values within the Tyresåns lake system, which spans multiple municipalities. Sigrid De Geyter will serve as a representative at the association's meetings until 2027, and Gabrielle Gjerswold and Bertil Timan are nominated for the board. This signifies Stockholm's active participation in efforts to protect and enhance the area's water environment.

Stockholm Vatten AB, responsible for the city's water and wastewater, will appoint representatives to Svenskt Vatten's annual meetings in 2026. Two representatives from the majority and two from the opposition will attend the Water Assembly in Malmö, and one representative will be appointed to represent the company at Svenskt Vatten's general meeting.

Stockholm Vatten AB requires an additional SEK 140 million to repair and replace an outlet pipe at the Henriksdal Wastewater Treatment Plant. The existing pipe, dating from the 1940s, is damaged and is releasing untreated wastewater near the shoreline at Saltsjökvarn, violating its environmental permit. The increased cost is primarily due to unexpected seepages of lake water during construction, necessitating extra measures to complete the project safely and environmentally responsibly.

Stockholm Water AB proposes approving an increased budget of SEK 38 million, to a total of SEK 60 million, for a project on Hornsbruksgatan. This is due to unexpectedly large amounts of rock and proximity to the subway, which is delaying the work to renew water and sewer lines for 36 new homes. The project is planned for completion in the third quarter of 2027 and aims to improve the water and sewer supply and reduce the risk of basement flooding in the area.

Stockholm Vatten AB plans to invest up to SEK 225 million to modernize and improve the treatment process at Henriksdal Wastewater Treatment Plant. The funds will be used to replace old machinery in the aeration basins (bioline 2-5) to ensure the plant can handle future wastewater treatment needs, especially with the connection of wastewater from Bromma Wastewater Treatment Plant. The work will be carried out in stages between 2026 and 2031.

Stockholm Vatten AB plans to replace a 470-meter main water pipe in Skarpnäck, on Gamla Tyresövägen, due to its sensitive concrete type which poses an explosion-like cracking risk. The new steel pipe will be thicker (from 600 mm to 800 mm) to secure water supply for parts of Stockholm, Nacka, Värmdö, and Tyresö, and to reduce flood risks, including in allotment garden areas. The project is estimated to cost 52 million SEK and also mandates the use of electric work vehicles to lower emissions and noise.

Stockholm Vatten AB plans to construct a stormwater park in Tenstadalen to treat stormwater runoff from the Lunda industrial area before it enters Bällstaån. The park aims to reduce pollutants such as phosphorus, copper, and zinc, which is crucial for improving water quality in Bällstaån and the Mälaren-Ulvsunda Lake. The project has experienced increased costs and delays compared to earlier decisions, partly due to poorer ground conditions and the cancellation of a planned collaboration with the City of Stockholm.

Stockholm Water AB is proposed to adopt a revised strategic decision for Central Bromma and Riksby, part of a larger program aiming to build approximately 1,450 homes and commercial spaces. The budget for the planning phase is increased by SEK 20.8 million to a total of SEK 45 million, with an estimated total project budget of SEK 636 million. This increase is primarily due to higher costs for ground reinforcement and adaptation of the water and sewer system, even though the project scope has been reduced from 24 to 16 blocks to improve profitability.

Stockholm Vatten AB plans to invest 250 million SEK in Svartvik, Huddinge municipality, to expand the water and sewer system. This investment is part of Huddinge municipality's plan to develop the area with approximately 400 new homes, replacing the current recreational cabins. The project includes constructing new pipelines and four pumping stations to enable municipal water and sewage services, a prerequisite for the new detailed development plan.

Stockholm Vatten AB intends to construct a new waterworks on Lovön, as current facilities are aging and cannot guarantee drinking water supply beyond 2045. The project is estimated at approximately 8.2 billion SEK, with a total budget of up to 10.6 billion SEK to account for risks and inflation. This initiative aims to secure future drinking water quality and capacity for the Stockholm region amidst population growth and climate change. Construction involves revoking a portion of the Lovön nature reserve and land acquisition, carrying risks of delays and cost increases.

The board of Stockholm Vatten AB has approved the financial report for November 2025. The report shows the company's loan debt at SEK 33,918 million, an increase of SEK 231 million from the previous month, with an interest rate of 2.65 percent. The company has received approval to increase its loan limit to SEK 43,000 million for 2026.
