Top 3 ways to Successfully Protect your Substation from Flooding


With over 55,000 homes and businesses being affected by the 2007 floods and wet winters being commonplace, g2 Energy take a look at what can be done to help protect substations from future flood damage.

  1. Flood Barriers
    Due to the remote location of substations, they need to be ‘self-sufficient’ when it comes to protecting themselves from flood damage. Flood barriers can either be temporary or permanent fixtures around a substation; they are designed to prevent flooding reaching behind the protected area. A great example is the Thames barrier albeit on a much larger scale than what most substations will require. Where space is limited flood barriers may not be a realistic option, but don’t despair there are other options.
  2. Flood Doors
    Replace access doors with flood doors. Flood doors can be installed to help protect your substation against intrusion from flood water, protecting the crucial operating equipment housed inside.
  3. Flood Pumps
    Installation of Sump pumps to your substation will help to remove water that gets through external defences. Most sump pumps are activated automatically through sensors so no manual interaction is necessary. One consideration of a sump pump should be their reliance on electricity to operate therefore back-up power sources should be looked into before installation.

If your substation is sited on, or near, an area which is at risk of flooding ensure that you have taken the necessary steps to protect it. Even though the UK government are planning to increase flood defences it could be years before some parts of the country are safeguarded.
