PU Kandavas pilsetas komunalais uznemums Liela iela 38 is an advanced wastewater treatment plant located in Kandava, Latvia. The facility serves a population of approximately 3,563 people, placing it in the small-to-medium agglomeration category under EU classification. The plant is situated in the Tukuma novads region, about 50 km from the Baltic Sea coast. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,583 m³/day and an average discharge volume of 513.74 m³/day, the facility operates well below its capacity, indicating potential for future growth or efficient water management. Treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Abava River and the Venta River system. The Baltic Sea is a sensitive marine environment, and advanced treatment helps reduce nutrient loading, protecting coastal ecosystems and supporting regional water quality goals.
Environmental context
The plant discharges into the Abava River, a tributary of the Venta River, which flows into the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. Advanced treatment at this plant helps reduce the risk of eutrophication in downstream waters, supporting the health of aquatic habitats and migratory fish species in the Venta River basin.
