Overview
PBU Dobeles udens is a wastewater treatment plant serving Krimūnu pagasts, Latvia, with a designed capacity of 1.00. It serves a population of approximately 12,187.
PBU Dobeles udens is a wastewater treatment plant located in Krimūnu pagasts, Dobeles novads, Latvia. It serves a population of around 12,187, classifying it as a medium-sized agglomeration under EU standards. As a Latvian facility, PBU Dobeles udens operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Latvia has transposed the directive into national law, and plants serving over 10,000 population equivalent must meet secondary treatment standards. The plant's location inland suggests it likely discharges into a freshwater body. Given its location in the Zemgale region, treated effluent likely flows into the Lielupe River basin or its tributaries, eventually reaching the Baltic Sea. The Lielupe basin supports diverse aquatic life and is an important ecological corridor in Latvia.
Environmental context
The plant is situated in the Lielupe River basin, which drains into the Baltic Sea. The Lielupe and its tributaries support a variety of fish species and aquatic habitats. The Baltic Sea is a brackish, semi-enclosed sea with sensitive ecosystems, making nutrient removal important for preventing eutrophication. The plant's discharge contributes to the overall nutrient load in the basin.
