KA Brome - Advanced Wastewater Treatment Plant in Altendorf, Niedersachsen

KA Brome is an advanced wastewater treatment plant located in Altendorf, within the municipality of Brome in the district of Gifhorn, Niedersachsen, Germany. The plant serves a population of 2,684 and has a designed capacity of 4,000 m³/day, with an actual discharge volume of 306.85 m³/day, indicating significant spare capacity. As an advanced treatment facility, KA Brome goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (2,684 PE), the directive requires at least secondary treatment, but the plant's advanced status suggests it operates in a sensitive area or meets higher local standards. The plant discharges treated effluent into local watercourses that ultimately drain into the Aller River system, a tributary of the Weser River, which flows into the North Sea. The region's lowland landscape and agricultural land use make nutrient removal critical to prevent eutrophication in downstream waters. The plant plays a key role in protecting the local watershed and the broader Weser basin.

KA Brome discharges into small streams that feed into the Aller River, a major tributary of the Weser River, which flows into the North Sea. The surrounding region is characterized by agricultural land and lowland heath, making nutrient pollution a key concern. Advanced treatment helps reduce nitrogen and phosphorus loads, protecting downstream aquatic ecosystems from eutrophication and supporting biodiversity in the Weser estuary.
