Municipal depot on the former WWTP site

The Luxembourg-Bonnevoie wastewater treatment plant was decommissioned in 2015. In 2020, the City of Luxembourg entrusted HOLINGER with the remediation of the site, the removal of pollutants and the demolition of various buildings. We are also building new halls for the maintenance and service department located there. Besides a vehicle and storage hall, the project includes a flushing system for the vacuum trucks and a photovoltaic system on the roof to produce sustainable energy. HOLINGER was responsible for the structural and mechanical engineering of the new building and was also entrusted with the site management.
