Primary function
Culvert, screen and outfall manual, (CIRIA C786) published by CIRIA in 2019, defines the primary function as: ‘ The main design or operational function of an asset.’
‘For a culvert, the primary function is to convey a drainage channel under an obstruction without excessive restriction. For an outfall, it is to discharge the flow from a drainage system into a receiving watercourse. For a screen, it will be either to trap debris in order to prevent a blockage downstream of to prevent unauthorised access.’
