Overview
SIA KP Tehnologijas is a secondary wastewater treatment plant in Ogre, Latvia, serving over 21,000 people with a designed capacity of 40,000 m³/day.
SIA KP Tehnologijas is a municipal wastewater treatment plant located in Ogre, a town in the Ogres novads region of Latvia. The plant serves a population of approximately 21,123, placing it in the medium agglomeration category under EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies. Its designed capacity of 40,000 m³/day indicates it is sized to accommodate future growth or seasonal peaks. As a facility in Latvia, it operates under national regulations that transpose EU directives, with oversight from the State Environmental Service. The treated effluent is discharged into the Daugava River basin, which flows into the Baltic Sea via the Gulf of Riga. The Daugava is the largest river in Latvia and supports diverse aquatic ecosystems, including migratory fish species. The plant's location about 50 km from the coast means its discharge contributes to the nutrient load entering the Baltic Sea, a sensitive marine environment subject to eutrophication concerns.
Environmental context
The plant discharges into the Daugava River basin, which drains into the Gulf of Riga and ultimately the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it highly sensitive to nutrient pollution. The Daugava River supports important fish spawning grounds and migratory routes. The plant's secondary treatment helps reduce organic load but may not fully address nutrient removal, which is critical for mitigating eutrophication in the Baltic Sea.
