Overview
TP 820 of Sysman kk is an advanced wastewater treatment plant in Sysmä, Päijät-Häme, Finland, serving approximately 3,100 people. It discharges treated wastewater into the local watershed near the coast.
TP 820 of Sysman kk is an advanced wastewater treatment facility located in Sysmä, within the Päijät-Häme region of Finland. The plant serves a population of around 3,100 residents, making it a small-scale municipal treatment facility. Its location near the coast places it in a sensitive environmental zone where treatment standards are critical for protecting Baltic Sea water quality. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive mandates secondary treatment, but Finland often applies tertiary or advanced treatment in coastal areas to reduce nutrient loads. The plant's discharge volume is reported as 508.08 units, reflecting its operational scale. The treated effluent from TP 820 of Sysman kk ultimately reaches the Baltic Sea via local rivers and lakes. The Baltic Sea is a semi-enclosed brackish water body highly sensitive to eutrophication from nutrient inputs. Advanced treatment at this plant helps mitigate phosphorus and nitrogen loads, supporting the ecological health of the coastal zone and contributing to regional efforts under the Helsinki Convention (HELCOM).
Environmental context
The plant discharges into the local watershed that drains into the Baltic Sea, a brackish sea with limited water exchange and high sensitivity to nutrient pollution. The region's lakes and rivers, such as Lake Päijänne, are important for biodiversity and recreation. Advanced treatment at this plant reduces nutrient loading, helping to combat eutrophication in downstream coastal waters and supporting aquatic life in the receiving water bodies.
