Ugales pagasta dzivoklu komunala dala - Closed Wastewater Treatment Plant in Ugāles pagasts, Latvia

Ugales pagasta dzivoklu komunala dala was a wastewater treatment plant located in Ugāles pagasts, Ventspils novads, Latvia. It served a small population of 683 residents in the rural municipality. The plant is now closed, but during operation it provided secondary treatment for the community. As a secondary treatment facility, the plant met the minimum requirements under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent above 2,000, though smaller plants like this one are also expected to provide appropriate treatment. The plant's designed capacity was 1,450 m³/day, with an average discharge volume of 130.36 m³/day. The plant's treated effluent was likely discharged into a local watercourse within the Venta River basin, which flows into the Baltic Sea. The region's aquatic ecosystems depend on proper wastewater management to prevent nutrient loading and maintain water quality.

The plant served the Ugāles pagasts area, which lies within the Venta River basin. The Venta River flows westward through Latvia and into the Baltic Sea near Ventspils. The Baltic Sea is a brackish, semi-enclosed sea sensitive to nutrient pollution from wastewater discharges. Proper treatment is essential to protect downstream aquatic habitats, including spawning grounds for fish and migratory bird stopover sites along the coast.
