Rostock is investing 67.6 million euros in water and wastewater safety!

On November 28, 2025, the Warnow Water and Wastewater Association (WWAV) and Nordwasser informed about important decisions affecting water supply and wastewater disposal in Rostock. A significant step for the infrastructure is the 2026 investment program, whose volume is an impressive 67.6 million euros. The aim of this comprehensive program is to ensure sustainable supply and disposal security and to address the challenges of climate change. Rostock Town Hall reports.

A look into the future shows that a big project is waiting for us on Herweghstrasse. A rainwater system will be installed there and the drinking water pipes will be replaced by April 2027. Comprehensive work on the pipe systems is also planned for Fritz-Reuter-Straße by June 2026, with the third construction phase lasting until 2029. In addition, pipeline work is pending in Warnemünde on Rostocker Straße, which will be completed by May 2026. These measures are part of a broader strategy that also focuses on adapting to climate change.

Major investments in the sewage treatment plant

The largest single investment will be the new construction of the mechanical pre-cleaning facility at the sewage treatment plant in Rostock, with costs of around 36 million euros. This new building is part of a comprehensive project that will create a new computing hall, a sand trap and a technical operations building over the next three years. Preparations for this are already underway, including explosive ordnance detection and the relocation of lines. In addition, further projects will begin from 2026, which will include, among other things, the renewal of a main transport pipeline for drinking water in Werftstrasse.

In the area around Rostock, a total of 9 million euros will be invested in 14 individual measures to expand the capacity of the networks and increase their resilience. These measures are essential to ensure safety standards and guarantee a future-proof water supply.

Adjustment of fees to ensure supply

One of the most important changes accompanying the new investment program are the increased fees for water and wastewater, which will come into force from January 1, 2026. The volume fee for drinking water increases by 9 cents and then amounts to 1.92 euros per cubic meter. For an average four-person household in a single-family home, this means an additional annual burden of around 150 euros. The basic fee for the smallest meter will also rise by 57 cents to 16.68 euros.

All of these adjustments are necessary to ensure the reliability of the water supply in the future. An increase in operating costs for energy, personnel and chemicals as well as the necessary construction projects are decisive for this fee adjustment, which is primarily intended to take into account the needs of a growing city. NDR provides further information on this.

In summary, it shows that Rostock has a good hand when it comes to finding sustainable solutions for water supply. Targeted investments in infrastructure and the associated adjustments to fees are a necessity in order to respond to the increasing challenges posed by climate change and urban growth and to ensure the quality of life of Rostock residents.
