A series of 36 artistic lids created as a result of a collaboration between the Lisbon sewage company Águas do Tejo Atlântico, and the manufacturer Saint-Gobain (PAm). The project called Há Art No Esgoto - there is art in the sewers, was done on the occasion of International Sanitation Day (November 19), and its purpose is to make people look at the sewer covers. On the caps appear central places in the city of Lisbon, with the illustrations made by Gilberto Gaspar.
On the current cover, you can see the statue of the Marquis de Pombal and the fountain located in the square named after him.
Although the cover bears the model name PAMREX, it is not similar to other covers of the same model.
