Hi!
You can make a Deposit of 10,000 l from barrels 1000 L. it is possible to buy used, not for drinking water. For example, for 10,000 litres will cost about 500-600 euros. Can be put on a concrete foundation or just on flat ground.
All these barrels have taps at the bottom and connected by means of pipes in your system. The pipes can be used from polyethylene. This is the most economical option. 8-)
I can give you such drums of 1000 l. And i can connect all the barrels. They are actually new. Used only once to transport liquids. 633371043 Max
