Details

This guide outlines a risk-based approach to assessing the need for and design and management of trash and security screens. It will be useful to Environment Agency staff, local authorities and others involved in the installation and operation of such screens.

The guide recommends that asset managers and planners carefully consider the need for a screen, and fully investigate alternative options. New screens should only be installed where the benefits are significant and outweigh the risks. The risk-based approach outlined in the report uses a scoring system based on identifying hazards and assessing the probability of them occurring. A risk score is then used to decide whether or not to provide a screen.
