Permeable block paving suitable for overflow? - Gutter to waterbutt over to drain

[Jon_P]

Hi, just found this site and am looking for some advice on whether my idea will work or is completly unsuitable.
I live in a link detached house, so have no access to the rear of the house other than going through the garage. The guttering drains to the front of the property, down a pipe into the ground. I've hooked up 2 water butts at the front to catch rainwater, but have to carry buckets through the garage to water the back garden.
At the back I have a patio with 3 large water butts which i manually fill with the buckets, but I also have a patio, about 5m x 5m, with a slope towards the house. 1 small drain which the kitchen sink and washing machine drain into.

Ideally i planned to put in an additional down pipe at the rear of the property, divert half the guttering to this downpipe, and have it fill the daisychained waterbutts. I'd then have an overflow from the last waterbutt onto the patio area, which needs repaving. Ideally i'd like to use permeable block paving that would then drain into the rear drain, giving me the benefit of a nice patio whilst saving some good rainwater for the garden without all the carrying of water.
The overflow would have to come from the waterbutts as they're at the end of the patio, a good 5 metres from the down pipe.
Completely inpracticle or just a challenge to get it working?

cheers

You could set up a pumping system through your garage, save you a lot of work carrying water. The rainy season and winter is almost here, so you have plenty of time to think about it before the spring. :;):

Submersible pump isn't expensive, I was going to say about a pumping main to the back of the house but thought it'd get poo-poo'd!
