From Risk to Resilience: Why Synthetic/Midel Oil Separators Matter More Than Ever

In critical infrastructure, prevention is rarely headline news. Unfortunately, failures often are. The events surrounding the North Hyde electrical substation fire near Heathrow Airport in March 2025 demonstrated just how significant the consequences of transformer-related incidents can be (original news article). Reports indicated that a transformer containing approximately 25,000 litres of cooling oil caught fire, […]

Do Attenuation Systems Require Upstream Treatment?

Put simply, the CIRIA SuDS Manual (c753) within the design assessment checklists require ‘suitable silt interception upstream’ of most attenuation systems. One of the central concepts of the SuDS Manual is that run-off should be treated as close as possible to source; it must then be attenuated and finally slowly released, in that order. Jo […]
