The New Rainwater Pit, about 2m cubed was overflowing after about 10mm of rain, so with another 60 falling later, imagine how much rainwater fell here. That photo was taken about 5 hours later. So it is obviously too small, especially considering it is supposed to be full of rubble, gravel and soil

The ‘Dig’ under the house was full of water about 5 hours ago. So much water came down in about 20 minutes, the new drainage pipe couldn’t handle it. I’ll have to extend the PVC down a bit further, methinks, at least temporarily.

The main culprit was the leaf guard which blocked the drainage grate and it overflowed. Didn’t realise until too late. Created loverly new channels through my just compressed roadbase :(

The overflowing water also uncovered the drain pipe, also I had to dig out again the trench I had dug previously and filed in two weeks ago to get the water away from the flood.
