A hopper for solids is disclosed which, in one aspect, has a main hollow body for storing the solids, an inlet for feeding solids into the main hollow body, a discharge section for discharging the solids from the main hollow body, and a plastic liner device loosely covering interior surfaces of the hopper. In one aspect the plastic liner device includes sub-parts, each sub-part secured to a sub-part of the main hollow body and/or to the inlet or discharge sections. In one aspect separate sealed compartments facilitating leak detection are formed between each liner sub-part and the wall of the main hollow body. Also disclosed is a hopper that provides both primary (liner) and secondary (hopper wall) containment.
