Overview
SIA Udeka is an advanced wastewater treatment plant serving Ventspils, Latvia, with a designed capacity of 30,000 m³/day. It treats wastewater for approximately 11,951 people and is located near the Baltic Sea coast.
SIA Udeka is a wastewater treatment plant located in Ventspils, Latvia, serving a population of approximately 11,951 residents. The plant is situated in the Vecpilsēta area and operates with advanced treatment capabilities, reflecting its role in protecting the local environment. With a designed capacity of 30,000 m³/day, the facility is equipped to handle current and future wastewater volumes from the Ventspils agglomeration. As an advanced treatment plant, SIA Udeka goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is particularly important for discharges into sensitive water bodies. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment, and the advanced level here indicates compliance with stricter standards for sensitive areas. The plant's operation is part of Latvia's commitment to EU water quality regulations. The treated effluent from SIA Udeka is discharged into the Baltic Sea via the Ventspils port area or nearby coastal waters. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution that can cause eutrophication. By providing advanced treatment, the plant helps reduce nutrient loads, protecting marine ecosystems and supporting the health of the Gulf of Riga and the broader Baltic Sea.
Environmental context
SIA Udeka discharges treated wastewater into the Baltic Sea near Ventspils, a coastal city on the eastern shore of the Baltic. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient inputs that can lead to eutrophication and algal blooms. The plant's advanced treatment helps mitigate these impacts by removing nitrogen and phosphorus, supporting the ecological balance of the coastal zone and the Gulf of Riga.
