Overview
Klanino wastewater treatment plant serves the village of Parszkowo in northern Poland, treating domestic wastewater for 982 residents with secondary treatment. The plant discharges 140.02 m³/day and is located within 10 km of the Baltic Sea coast.
Klanino wastewater treatment plant is a municipal facility located in Parszkowo, a village in the Puck County of Pomeranian Voivodeship, northern Poland. The plant serves a population of 982 and operates with secondary treatment, which is the standard level required under Polish and EU regulations for small agglomerations. Its designed capacity is 3,398 m³/day, with an actual discharge volume of 140.02 m³/day, indicating significant spare capacity. As a Polish wastewater treatment plant, Klanino operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 15,000 discharging into coastal waters. Although the plant serves fewer than 2,000 people, it still meets the secondary treatment standard, reflecting Poland's commitment to protecting the Baltic Sea. The plant's proximity to the coast (within 10 km) places it in a sensitive area where nutrient removal may be required to prevent eutrophication. The treated effluent from Klanino ultimately reaches the Baltic Sea, a semi-enclosed sea with significant ecological challenges, including nutrient pollution and algal blooms. The plant's location in the coastal zone of the Puck Bay area means its discharge contributes to the overall nutrient load in the region. By providing secondary treatment, the plant helps reduce organic matter and suspended solids, supporting the health of the Baltic Sea ecosystem.
Environmental context
Klanino treatment plant discharges into local watercourses that drain into the Puck Bay, part of the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient inputs. The plant's coastal location means its effluent can influence local marine habitats, including seagrass meadows and fish spawning grounds. Effective treatment is critical to minimize eutrophication and protect the region's biodiversity.
Frequently asked questions
The Klanino wastewater treatment plant is located in Parszkowo, a village in the gmina Krokowa, powiat pucki, Pomeranian Voivodeship, Poland. It is situated near the Baltic Sea coast, within 10 km of the shoreline.
The plant serves a population of 982 residents, making it a small-scale municipal facility. It is designed to handle a capacity of 3,398 m³ per day, with an actual discharge volume of 140.02 m³ per day.
The plant provides secondary treatment before discharging the treated effluent into local watercourses that flow into the Puck Bay and ultimately the Baltic Sea. The discharge volume is 140.02 m³ per day.
As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment. For coastal discharges, secondary treatment is required for agglomerations above 2,000 PE, but the plant's secondary treatment aligns with best practices for protecting the Baltic Sea.
In Poland, small wastewater treatment plants serving populations under 2,000 often use secondary treatment technologies such as activated sludge or biological filters. The EU directive encourages appropriate treatment to prevent pollution, especially in sensitive coastal areas like the Baltic Sea region.
