The origin of the pollution was traced to a building site located at the intersection of Rue Baudouin and Route d'Esch.
Concrete and dirt were poured into the sewers by means of a pipe connected to a pump.
The competent authorities of the municipality of Luxembourg City and the Water Management Administration have been informed and the necessary measures have been taken. The police have drawn up a report.
The Pétrusse had already been polluted in the same place at the beginning of October. At the time, the site foreman in charge was sanctioned.
