Think in layers

Flood protection works best as several small defences, not one big one. Each layer buys you time or reduces damage.

Six steps

  1. Know your risk. Ask neighbours where water gathers and how high it has come before. Mark the highest level on a wall or gate post.
  2. Raise floor levels. In new buildings, set the floor above the highest known water level. A raised plinth is far cheaper to build than to fix later.
  3. Direct water away. Slope the compound away from the house, and make sure gutters, drains and the compound gate do not let water pool against walls.
  4. Keep drains clear. Clean the drain in front of your gate before the rains, and never throw refuse into it.
  5. Protect what matters. Put sockets and meters higher on the wall, and keep important papers and electronics above the flood line.
  6. Have a plan. Agree on where the family will go, what to carry, and who to call. Keep a torch and a charged phone ready.

What not to do

  • Do not block a neighbour’s drainage path with a wall or extension.
  • Do not pave the whole compound. Leave soft ground so rain can soak in.
