SIA Auces komunalie pakalpojumi Wastewater Treatment Plant, Auce, Latvia

SIA Auces komunalie pakalpojumi is a municipal wastewater treatment plant located in Auce, a town in the Dobeles novads region of Latvia. The plant serves a small population of 178 residents, reflecting the rural character of the area. It is situated at 24 Puškina iela, Auce, and operates as a key facility for local wastewater management. The plant provides secondary treatment, which is the standard biological treatment level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 2,000. The designed capacity of 3,000 m³/day indicates the plant's ability to handle peak flows, while the actual discharge volume of 202.41 m³/day suggests a low utilization rate, typical for small communities with stable population levels. The treated effluent is discharged into local water bodies, ultimately draining into the Baltic Sea via the Lielupe River basin. The plant's inland location, over 50 km from the coast, reduces direct marine impact. However, its discharge contributes to the overall nutrient load in the Baltic Sea, a sensitive ecosystem affected by eutrophication. The plant's secondary treatment helps reduce organic pollutants and suspended solids, supporting the health of downstream aquatic habitats.

The plant discharges into local streams that are part of the Lielupe River basin, which flows into the Baltic Sea. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient pollution. The plant's secondary treatment reduces organic matter and nutrients, helping to mitigate eutrophication in downstream waters. The surrounding area is primarily agricultural, so the plant's role in controlling nutrient loads is important for maintaining water quality in the region.
