Overview
SIA Tukuma udens serves the Smārdes pagasts area in Latvia's Tukuma novads, treating wastewater for a population of 46,184. The plant is located inland, contributing to local water quality management.
SIA Tukuma udens is a wastewater treatment plant located in Smārdes pagasts, Tukuma novads, Latvia. It serves a population of 46,184, classifying it as a medium-sized agglomeration under EU standards. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a facility sized for this population tier. As a Latvian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this scale. Latvia's implementation of the directive ensures that plants like SIA Tukuma udens meet effluent standards for biological oxygen demand and suspended solids, protecting receiving waters. The plant discharges into local water bodies within the Lielupe River basin, which flows into the Baltic Sea. Its inland location reduces direct marine impact, but proper treatment is essential to prevent nutrient loading in the Baltic, a sensitive semi-enclosed sea prone to eutrophication.
Environmental context
The plant's treated effluent enters the Lielupe River basin, which drains into the Gulf of Riga and ultimately the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. Effective wastewater treatment at plants like SIA Tukuma udens helps reduce nitrogen and phosphorus loads, supporting the health of downstream aquatic ecosystems and mitigating algal blooms.
