Overview
PU Varaklanu pilsetas DzKU is a secondary wastewater treatment plant serving Varakļāni, Latvia. It treats wastewater for approximately 1,148 people with a designed capacity of 1,200 m³/day.
PU Varaklanu pilsetas DzKU is a municipal wastewater treatment plant located in Varakļāni, a town in eastern Latvia. The facility serves a population of approximately 1,148 residents, classifying it as a small agglomeration under EU standards. The plant is situated on Pils iela and operates as part of Latvia's national wastewater infrastructure. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity of 1,200 m³/day accommodates the town's wastewater flow, with a reported discharge volume of 178.62 m³/day. Treatment processes typical for secondary plants in Latvia include biological treatment followed by sedimentation. Treated effluent is discharged into a local watercourse that ultimately drains into the Daugava River basin, which flows into the Baltic Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution and organic loading, supporting the ecological health of downstream aquatic habitats.
Environmental context
The plant discharges treated wastewater into a local stream within the Daugava River basin. The Daugava River flows through Latvia and into the Gulf of Riga, part of the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea sensitive to eutrophication from nutrient inputs. The plant's secondary treatment helps reduce organic matter and nutrients, mitigating the risk of algal blooms and oxygen depletion in downstream waters.
