Water feature project...

Hi all,

Would live to get some opinions...

We have a small pond on one level of the garden, right at the top of a few metre bank down to another level... My plan...

Dig a cubic metre hole on bottom level. Cutvtge top off a caged 1000 litre ibc tank and put in hole. Cover top of tank in geotextile fabric. Build small pond area on top of buried tank.
Create river using pond liner and stones down bank from top pond to bottom pond. Pump water out of sump back into top pond....

Thoughts?

Thanks!

You don't say how steep it is, but my immediate thought is that it's going to look like pond liner, because any stone you might put it in will just flow downhill. You may or may not think this is a problem.
IIWY, I would be tempted to make it series of stepped rills that flow into each other.
It's not clear what purpose the IBC tank serves? If you build a pond over it and your pump is in there then that's going to be a maintenance nightmare.

I think I will build the actual river out of stone, sand and cement, on top of pond liner...

I don't actually want a pond on the bottom level... So perhaps the buried tank just needs to act as a sump.

The bank is currently quite steep, but will have a digger on site soon so could change that...
