Have no idea how much our tanks hold, but we have 2. The concrete tank is bigger than our plastic tank.
We've run out about 3x since living here [oct 07]. Costs $140 to get a load of water, that about 1/2 fills our smaller tank.
We have a system now as water has been a real issue for the past 18mths. Concrete tank is the one we use the water out of. Both are hooked up to the house, but to keep an eye on what we have we have the plastic one turned off. The water from the roof feeds into the plastic one, so we can keep an eye on what we have as backup. When the concrete one runs out, we turn on the plastic tap for about an hour to feed water over to the concrete one. Then switch it off again. A foot or two of water can last about 4-5 days if you're careful... but that's minimum washing too [and 7 house occupants]. Right now my laundry is full of dirty washing and I can't do anything about it.
Bath water is used for the washing machine & toilet. Toilet tap is ALWAYS turned off. I never realised just how much water toilets waste until I lived here! We also have a bucket in the shower to catch water for the toilet/washing machine as well.
I have a river pump here as well, that we use for washing sheets & blankets when it's clear enough. Right now though it's beyond filthy and I wouldn't let the dog swim in it, let alone wash with it!
I have no idea on gas bottles though. We have normal leco here for everything. But I'll be keeping an eye on this thread because we are looking at a house that uses gas bottles & solar...
We used to use bath water for the toilet too. We put in a dual flush for the tenants - there's two of them and there were 4 of us.
We took our washing to the laundromat in the next town once a week to save water.
Getting gas bottles for the new house, just for the stovetop and heating (eventually) and solar hot water but not power. We're going to get a big rainwater tank (23,000L) there too for showers but the house is on mains, and the rainfall here is higher than at my old house. Rainwater showers are so nice
