"Consider how much weight is in 50 meters pipe full of water, need I say more?"

DYOR ! How would it support passionfruit, whatever, without support posts?

Support, support!!! Approx. 19 over a 50 metre span.

Even empty pipe would sag to the ground over 50 metres.

Done properly, tank cold be hundreds of metres away from house, need I say any more?

A single 6 metre 90 mm pipe will sag around 1 > 2 metres, depending on where it is picked up from.

Therefore it NEEDS support, weight of 50 metres of 90 mm pipe, full of water, if it was full,

which it never will be, is 290 kgs.

Same if you made a raft, it would support 290 kilos, minus the weight of the pipe, so around 260 kgs.
