Overview
PU Musu saimnieks is a secondary treatment plant serving Vecumnieku pagasts, Latvia. It treats wastewater for approximately 966 people with a designed capacity of 2,700 m³/day.
PU Musu saimnieks is a municipal wastewater treatment plant located in Vecumnieku pagasts, Bauskas novads, Latvia. The facility serves a population of around 966 residents, classifying it as a small agglomeration under EU standards. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Its designed capacity is 2,700 m³/day, with a reported discharge volume of 126.22 m³/day, indicating significant spare capacity. The treated effluent is discharged into a local watercourse, likely part of the Lielupe River basin, which flows into the Baltic Sea. This discharge supports the ecological health of the downstream environment, including the Gulf of Riga, a sensitive marine area.
Environmental context
The plant discharges into a local stream within the Lielupe River basin, which ultimately drains into the Baltic Sea via the Gulf of Riga. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it sensitive to nutrient pollution. Secondary treatment helps reduce organic load and nutrients, protecting downstream aquatic ecosystems and supporting biodiversity in the region.
