Part of the old conduits (300 metres) was contaminated with asbestos. The old conduits were removed once an asbestos removal plan had been approved.

The old grey cast-iron pipes were replaced with new cast-iron conduits.

Access to the work areas was provided by four work shafts.

This work was carried out in the sewer under rue de Crimée and rue Botzaris in the 19th district of Paris.
