hi ,fieldsy.
I have ro-man 200 gpd system. produces 27 litres an hour.
625 litre tank (managed to fit in back of my ford escort), when i bought it. from pensteel, £125
I live in waltham abbey, essex junction 26 M25.
Unfortunately my setups at my parents, my place to small

My water producing system is bigger than i need but i did this as it's not at my place, just let my dad run until full then got 3 days water

With rain butts i could see over spills

.
It's up to you mate but in my opinion it's better to have a bigger setup running at half pelt than running a small one at full pelt.
If i'm to far away i'm sure someone on here will glady spare you some time.
all the best lee.
Might be back on later, letting 4 yr old daughter play cee-beebies games now
