The pond 20 minutes after heavy rain, fuller than usual but coping easily

Today we have had the most amazing heavy rain and it was a really good chance to see how the Sustainable Urban drainage System coped with the downpour. Although I did not venture out during the rain the whole of 6U came with me to have a look 20 minutes later. We found that the swales (ditches) coped easily and that the pond simply swallowed up the extra water and helped clear some of the algae that has been forming in the pond out of the way. Though the algae is now partly blocking the outfall and we will need to keep an eye on this. It was impressive though to see just how much water can be absorbed by this system when all the traditional drains were struggling.
