Overflow Weir Sizing Criteria All facilities must be designed without overflow weirs wherever possible. Flows in excess of the water quality volume must be conveyed away from the facility via a flow splitter. Design of the overflow weir or structure, if required, is largely dependent upon the way flows are delivered to the facility. WebTo ensure that adequate overflow provision is made, and any surcharge is accommodated, the overflow weir of the rainhead must be sized to AS/NZS 3500.3 and be fully open above the weir at the front of the rainhead. Overflow devices that discharge from a rainhead do not require an increase in depth of flow in the box gutter. did aoba johsai ever go to nationals
