waterbutt question

There isn't a convenient place to site a water butt to take water off the house roof but there is off the (single) garage roof, is that enough water to make it worthwhile, expense and botheration wise? I can collect kitchen sink water also, at least that's free

Once you rig one up to the garage you'll be amazed at how quickly it does mount up. But we're in 2 minds about getting one too because of the inital outlay expense.spendy/she/her ***DEBT-FREE DATE: 11 NOVEMBER 2022!*** Highest debt: £35k (2006) MY WINS: £3,541 CASH; £149 Specsavers voucher; free eye test; goody bag from Scottish Book Trust; tickets to Grand Designs Live; 2-year access to Feel Amazing App (worth £100); Home Improvement & Renovation Show tickets; £50 to spend on chocolate; Harlem Globetrotters tickets; Jesus Christ Superstar tickets + 2 t-shirts; Guardians of the Galaxy goody bag; Birmingham City v Barnsley FC tickets; Marillion tickets; Dancing on Ice tickets; Barnsley FC v Millwall tickets0

We have two, neither off the house roof. Our house has been extended at different times so we have two added on bits,single storey with sloping roofs (rooves?) and have sited water butts on them. Both fill up over the winter so, yes, worthwhile.0

If you want to do some sums you can roughly work out how much rain you'd need to fill a butt.
Using round figures... rounding pi to three...
If your water butt is 1 mtr in diameter...
then it's area is (pi x r ^2)... 1/2 x 1/2 x 3 = 3/4 of a square metre.
If it is also 1 metre high then its volume (area x height) is 3/4 x 1 = 3/4 cubic metres.
Now for your garage roof. Just measure your floor area and halve it for a rought guide.
If your roof is 4 metres long by 4 wide and apexed the area is 4 x 4 = 16 and half of that is 8 square metres.
So now we need to know what depth of water on the roof is needed to fill the butt.
depth times area = volume
depth times 8 = 3/4
Which is 3/4 divided by 8 which is a bit over 9cm or 3-4 inches of rain.
Anything over that as reasonably regular rain in say, a month, will keep you well topped up.

Call your council - we bought ours several years ago discounted via the Council, they held a "sale" of them in a field one Sunday morning. We bought our compost bin the same wayGive them a call and check out if they have/plan to have a similar scheme. Best of British

Squeaky - I was just hoping for YES, it's worthwhile or NO, don't bother - now you've given me homework to do!!!! you mention an apex on the roof, there isn't one, it's flat so it's only the size of the floor. Cheshire is pretty well average for rain I'd say0

We sort of have a water butt, only ours is just an old plastic fruit syrup barrel with the top cut off. It's only under one down pipe but it seems to collect loads of water and I just dip my watering can into it when I need to water the plants.
My answer would be a straightforward YES. Saving any water, no matter how little can only be a good thing.Organised people are just too lazy to look for things
