Hi,
I posted this before, seems like it might be relevant here.
Giving the garden a good watering was taking 400-500 litres of water per night at a cost of nearly a pound a go. This was pretty expensive last summer.
I've bought 3 large (200 litre) water butts, a large submersible pump and some hoses and with a bit of rerouting of our waste water piping I'm collecting nearly that amount of water a day from showers and baths and although I still have one water butt to install the system is in and working a treat!!
The pump states it can shift 130 litres a minute, and whilst this is clearly reduced down 15 metres of 15mm hose, there is still enough flow to run two hoses (sairee/emily and I can water the garden together now) at a similar rate that I used to get from the outside tap.
Really pleased with the system, total cost about £100 I'd say - the pump even has a float switch, so switches off when the butts are empty.
See attached pictures below:
This shows the submersible pump and my two-way adaptor that I made from a hoselock 3way splitter and some epoxy.

Two of the three water butts at the side of the house, the large white pipe carries both bath, shower, basin and all rain water from the roof.

The pump in place in one of the butts, you can see the float switch

The two hoses, I bought a 30m hoselock professional hose (really good hose actually) and cut it in half giving two 15m hoses

This shows the 15mm copper links between the bottom of the tanks, this keeps the levels in them all the same.

All in all a sucessful project, needs a bit of finishing off, I'm fitting an outside socket, cut the lids to shape, fit the final water butt in place, but it's working really well, I gave the grass the full 400 litres yesterday and it's looking really green and lush, and best of all it didn't cost be a penny - well aside from the 100 or so quid, but I love gadgets.
Here's the pump

Hope it is of some help.
