The Passive Tailings Compactor is a system of components for facilitating the continuous passive drainage and consolidation of fine-grained sediments in active and continuous deposition environments. The invention consists of a flotation device, an anchor mass, and a drainage conduit which acts as a tether between the flotation device and the anchor. The flotation device also serves to orient the drainage conduit horizontally. As water or sediment levels rise, the flotation device rotates, releasing drainage conduit wrapped around its axis. This allows the flotation device to move upwards, extending the drainage conduit passively. The flotation device uses asymmetrical fixed weights to resist lesser rotational forces. The drainage conduit serves to create a path of relatively high hydraulic conductivity, protected by a filter barrier, for the dissipation of pore pressures and consolidation of buried sediments. The anchor mass fixes the system in place.
