KA Gr Lafferde Wastewater Treatment Plant, Ilsede, Niedersachsen

KA Gr Lafferde is an advanced wastewater treatment plant located in the Groß Lafferde district of Ilsede, in the Landkreis Peine region of Niedersachsen, Germany. The plant serves a population of 2,654 and is designed to handle up to 3,500 m³ of wastewater per day, with an average daily discharge of 718.14 m³. As an advanced treatment facility, KA Gr Lafferde goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant operates under Germany's national water management framework, which implements EU directives and sets high standards for effluent quality. The treated wastewater from KA Gr Lafferde is discharged into local watercourses that eventually drain into the Fuhse River, a tributary of the Aller, which flows into the Weser River and ultimately reaches the North Sea. The plant plays a key role in protecting the region's aquatic ecosystems and groundwater resources from nutrient pollution.

The plant discharges into the Fuhse River basin, which flows into the Aller and then the Weser, eventually reaching the North Sea. This watershed supports diverse aquatic life and is used for agriculture and recreation. Advanced treatment helps reduce nutrient loads, protecting downstream water quality and preventing eutrophication in sensitive areas.
