A system includes a solids trap disposed in a well. The system includes an inner annulus, an outer annulus, and a chamber between the inner annulus and the outer annulus. A solids accumulation zone is formed in the chamber. A pump is fluidly connected to the solids trap. A fluid stream carrying solids flows from the pump. The fluid stream carrying solids is configured to follow a path delimited by the outer annulus and the chamber until the fluid stream deposits the solids in the solids accumulation zone and departs the solids trap via the inner annulus into a tubing.
