Overview
Lipno wastewater treatment plant serves the town of Lipno in województwo kujawsko-pomorskie, Poland. It treats wastewater for approximately 26,411 residents under EU regulatory standards.
The Lipno wastewater treatment plant is located in Lipno, a town in the kujawsko-pomorskie province of north-central Poland. Serving a population of around 26,411, the facility is a key component of the local municipal infrastructure, managing domestic wastewater from the community. As a Polish plant serving a medium-sized agglomeration, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for populations between 10,000 and 150,000. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, which is common in the Baltic Sea catchment. The treated effluent is discharged into local waterways that ultimately drain into the Vistula River basin and then into the Baltic Sea. This makes the plant's performance important for reducing nutrient loads and protecting the sensitive marine environment of the Baltic, which is prone to eutrophication.
Environmental context
The plant discharges into the Vistula River basin, which flows northward into the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea highly sensitive to nutrient pollution, where excess nitrogen and phosphorus from wastewater contribute to algal blooms and oxygen depletion. Effective treatment at Lipno helps mitigate these impacts and supports the health of downstream aquatic ecosystems.

The treated effluent is discharged into local waterways that are part of the Vistula River basin, which ultimately flows into the Baltic Sea.
As a Polish plant serving over 10,000 people, it must comply with the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment and, if discharging into sensitive areas, more advanced treatment to reduce nutrients.
Under the EU directive, plants serving 10,000 to 150,000 people must provide at least secondary treatment. In Poland, many such plants also incorporate nutrient removal to protect the Baltic Sea, which is a sensitive area.
