PVC rainwater catchment

Hello,

So as I see people harvest rainwater, I almost always see them use PVC pipes, tanks, gallons etc.

Knowing that PVC is the most poisonous plastic available, do any of you guys know an alternative to using ANY plastic?

note: I am not in position to buy expensive metal tanks. I am looking for something that is as well safe, cheap and easy.

Thanks,

Bert

Concrete!

Well, for the tank ferrocement is relatively inexpensive if you have the workers needed for the size of tank you want, although cement is not very environmentally friendly. Constructing a Ferrocement Tank is a good place to start learning about this option. Although pvc is the cheap easy material for household pipe, I believe water tanks and irrigation pipe use polypropylene or polyethylene rather than pvc; not sure if that distinction makes a difference. I've read about inexpensive water tanks using EPDM pond liners contained within chain link fence reinforced with steel cable hoops, but I can't find a link.
