&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[https://www.ciria.org/ItemDetail?iProductCode=C786F&amp;amp;amp;Category=FREEPUBS 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.’&lt;br /&gt;
&lt;br /&gt;
‘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.’&lt;br /&gt;
