Sounds like you need a storage tank. We have a 3600 gallon storage tank, and if we are careful with water we can make it last a month. Even a thousand gallon tank can be made to last a week. Ours is on a tower gravity feed but it doesn’t need to be. And a small 10-15 gallon per minute pump will still give a decent shower.
All I need is that Hot shower in the morning
otherwise I’m a
Walking Zombie.
I’ll have to admit
Getting dressed by
Candlelight is kinda,
Well,
Exciting.
