Capacity of Drainage

To select the gutter size appropriate to your requirements, two factors must be taken into consideration. Roof Area Gutter Flow Capacity For further reference refer to BS EN 12056-3 “Roof Drainage Layout and Calculation”. The capacity of a drainage system should be large enough to carry the expected flow at any point in the system. The flow of ‘run-off’ depends upon the area to be drained, (the ‘effective roof area’), and the intensity of rainfall. It is accepted that 75mm an hour is the intensity of rainfall in the United KingdomFor further information, see the FloPlast “Gutter calculator” at www.floplast.co.uk .
