Karsavas NAI is a municipal wastewater treatment plant located in Kārsava, a town in the Ludza Municipality of eastern Latvia. The plant serves a population of approximately 380 people, reflecting its role in a small agglomeration. It is situated inland, away from coastal areas, and operates within Latvia's regulatory framework for wastewater management. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 600 m³/day and a current discharge volume of 98.34 m³/day, the plant operates well below its capacity, indicating potential for future growth or efficient current operations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent from Karsavas NAI is discharged into a local water body, which eventually drains into the Daugava River basin, a major river system in Latvia that flows into the Baltic Sea. The plant plays a crucial role in protecting the local watershed from pollution, supporting aquatic life and downstream water quality in the region.
Environmental context
