Grilles

Tender description

Grilles are an important part of DFI Rivers defences against flooding and they are normally positioned at the upstream entrance to piped and culverted watercourses. They trap debris to prevent it from entering the system and causing an obstruction within that cannot be cleared until the flood waters have subsided. This has serious implications for risk to life, damage to properties and can cause essential infrastructure to fail. The structure is designed to trap debris at one location and provides a safe access for Rivers officers to inspect it and safely remove any build-up of debris or obstruction trapped by the grille.
