Fact: Collecting rainwater can help to reduce flood risk
If you’re spending time in your garden this summer, why not consider what you could do to help collect rainwater.
By getting a water butt in your garden, you could:
- use it to water your garden
- help to stop rainwater overwhelming drains and sewers, which can help to reduce the risk of surface water and sewerage flooding
- use it as a mini ‘leaky dam’ by keeping the tap open during heavy rain, to slow down how quickly water reaches drains and sewers, again reducing the risk of overwhelming the network. Slow the Flow have advice on how you can even modify it to make sure you keep a water supply for your garden

These measures also help you to save water, which can help if we have a dry summer.
You can find more tips on how to save water and buy a water butt online at Welsh Water or Hafren Dyfrdwy. Or you buy one at most garden centres or DIY shops.
Fiction: ‘Flood risk’ is the likelihood of flooding happening
'Flood risk' is not just the likelihood of flooding; it also includes the possible damage a flood could cause. When we talk about 'flood risk', we are referring to a combination of two things:
- The likelihood of a flood happening
- The impact or consequences that will result if flooding occurs
So increased flood risk may describe a range of different scenarios.
In our 5 day flood risk, we include an overall summary of the forecast, and the daily flood risk for each local authority in Wales.
Below are two different examples of low flood risk:
Scenario A: There’s confidence that flooding will happen but we only expect there to be minor impacts. For instance, expecting roads or low-lying land to flood in the next few days.
Scenario B: There’s uncertainty if flooding will happen, but if it did, there could be significant impacts. An example of this is heavy rain and thunderstorms in summer. It isn’t possible to know if they will definitely happen, or exactly when and where, and if they did happen there could be flooding to properties.
