Ravlanda avr verk - Advanced Wastewater Treatment Plant in Rävlanda, Sweden

Ravlanda avr verk is an advanced wastewater treatment plant located in Rävlanda, Härryda municipality, Västra Götaland County, Sweden. The plant serves a population of 3,523 and has a designed capacity of 3,000 m³/day, with an actual discharge volume of 553.04 m³/day, indicating it operates well below its capacity. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal and disinfection, ensuring high-quality effluent before discharge. The treated effluent is discharged into a local watercourse that eventually drains into the Kattegat, a part of the North Sea. The plant plays a crucial role in protecting the local aquatic environment and downstream ecosystems, including the sensitive coastal waters of the Kattegat, which support diverse marine life and are important for fisheries.

The treated effluent from Ravlanda avr verk is discharged into a local stream that flows into the Göta älv river system, which ultimately drains into the Kattegat, a shallow sea area between Sweden and Denmark. The Kattegat is an ecologically sensitive region that supports diverse marine life, including fish stocks and seabird populations. The plant's advanced treatment helps minimize nutrient loading and protect water quality in this important coastal environment.
