Overview
Vilakas NAI Bio 240 is a closed secondary treatment plant in Viļaka, Latvia, that served 773 people. It had a designed capacity of 500 m³/day and discharged 147.53 m³/day.
Vilakas NAI Bio 240 was a wastewater treatment plant located at 20 Garnizona iela in Viļaka, a town in the Balvu novads region of Latvia. The plant served a population of 773 and was designed with a capacity of 500 m³/day, with an average discharge volume of 147.53 m³/day. It provided secondary treatment before its closure. As a plant in Latvia, it operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive aims to protect water bodies from eutrophication and pollution. The plant's closure may reflect upgrades or consolidation in the region's wastewater infrastructure. The plant's discharge likely entered local surface waters, contributing to the broader Daugava River basin, which drains into the Baltic Sea. The Baltic Sea is a sensitive ecosystem facing eutrophication challenges, making proper wastewater treatment critical for its health.
Environmental context
The plant's discharge would have entered local streams and rivers within the Daugava River basin, ultimately flowing into the Baltic Sea. The Baltic Sea is a brackish inland sea with limited water exchange, making it highly sensitive to nutrient pollution from wastewater.
