It is often prudent to assume that maintenance will be intermittent and to include a clogging factor into engineering calculations to account for periods in which the debris has not been removed.

A suggested value of 0.5 is often adopted. This is equivalent to 50 % of the cross-section of the structure being clogged during the flow being calculated. Note though that in the orifice equation (for example) the clogging factor goes up to indicate that 100 % of the flow can pass when factor = 1 and the factor goes down as the device clogs.

e.g. In the image on the left 23 % of the grate is impassable. The clogging factor is 1.00 - 0.23 = 0.77.
