In recent years, the European Investment Bank (EIB) has established itself as the EU’s Climate Bank, dedicated to promoting environmental sustainability as one of its core missions. Reflecting these values, the EIB’s new building is designed as a Nearly Zero Energy Building (NZEB). This innovative facility is being constructed by Rizzani de Eccher (leader) in a Joint Venture with the Dutch construction group Ballast Nedam.
A closed-circuit Wastewater treatment station for treatment of the effluent water from washing the Concrete pumps was implemented for the construction site of the new EIB Building project in Luxembourg. We are very proud that we have been awarded by BRE Global a BREEAM Innovation credit in December 2024 as no process of this nature has ever been implemented in the Construction sector.
The system consists of an initial sedimentation step followed by treatment by addition of flocculant and pH adjustment to allow agglomeration of lower diameter suspended matter for sedimentation in the next step. Finally, a filtration stage is added for filtration of even lower diameter suspended matter.
The benefits of the system are:
- Environmental by reduction of water use in the construction site and avoidance of the environmental impact of discharging highly alkaline wastewater with high solids content
- Social by resource conservation and avoidance of environmental impact to soil, air, water courses
- Economic by enhancement of concrete operations
The development and implementation of the Wastewater treatment station for the treatment of Concrete pumps washing water is a major action that demonstrates our commitment towards Sustainable development.
