Abstract

A water retention and flow control tank is divided into a head development chamber (2) and a much larger retention chamber (3) by a baffle-weir (4) which provides an overflow from the head development chamber (2) to the retention chamber (3). The head development chamber (2) has an outlet (7) associated with a vortex flow controller (8), and there are non-return flap valves (10) which allow the retention chamber (3) to drain back into the head development chamber (2) whilst preventing substantial flow from the head development chamber (2) to the retention chamber (3). When there is e.g. heavy rainfall, the water level builds up very quickly in the head development chamber (2) and the vortex flow controller (8) rapidly reaches its operating head, ensuring that the water discharge from the tank is at a predetermined maximum flow rate for the maximum period of time.
