A container can be placed on the outer surface of a manhole cover of a system for collecting liquid fluids from an industrial facility, the container (11) being made of a mesh grating material covering the entire outside part of the manhole cover. The container (11) defines a closed area filled with a solid material such that a liquid can pass through the container (11) filled with the solid material, by means of gravity, and enter the fluid collection system through the manhole cover. It also presents a barrier to the outflow, into the atmosphere, of vapours produced by a phenomenon of evaporation of the liquid that flows through the fluid collection system. |
