ABSTRACT:
A storm overflow basin for use, e.g. in combined sewage systems has a storage tank leading to a storm overflow unit having a restricted sewage discharge and a storm overflow, the latter being provided with a weir at which there is mounted a flap gate engaging the crest of the weir with its bottom edge and being operable by float controlled means in dependence upon the water level in the storm overflow unit, to move away from the crest of the weir when storm conditions require a controlled overflow discharge. The normal sewage discharge is provided with restriction means that are also float controlled.
