Abstract

The present disclosure provides a dewatering tank that is configured to retain fines in suspension. The tank comprises a floor portion that has a downward inclination. The tank further comprises a sump that is located such that the floor portion inclines towards the sump. The tank has an inlet for admission of water containing the fines and an outlet that is adapted for connection with a pump to discharge the water containing the fines from the tank and that is located in the sump. The tank is arranged such that the water flows from the inlet to the outlet. The tank comprises a wall or cover portion that is positioned to divert a flow of the water away from a direct flow direction from the inlet to the outlet in a manner such that turbulences are induced and fines that may otherwise settle in the sump and on the floor portion are suspended.
