Perl Besch Wastewater Treatment Plant - Advanced Treatment in Perl, Luxembourg

Perl Besch is an advanced wastewater treatment plant located in the town of Perl, within the Saarland region of Luxembourg. The plant is situated near the German border and serves the local population and industrial areas. With a designed capacity of 23,000 cubic meters per day, it is a medium-sized facility that plays a key role in managing wastewater for the region. As an advanced treatment plant, Perl Besch likely employs tertiary processes such as nutrient removal or disinfection, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates advanced treatment for agglomerations over 10,000 population equivalent in sensitive areas, which applies to this region given its proximity to the Moselle River basin. The treated effluent from Perl Besch is discharged into local watercourses that ultimately drain into the Moselle River, a major tributary of the Rhine. The Moselle supports diverse aquatic life and is an important ecological corridor. The plant's advanced treatment helps protect water quality in this transboundary river system, benefiting both Luxembourg and downstream communities in Germany.

Perl Besch discharges treated wastewater into local streams that flow into the Moselle River, a major tributary of the Rhine.
