It's only $100 more than what I paid for my submersible. I just put another 750L into the IBC with it. I'm pretty impressed it can pump it 3m high in a 2inch lay flat hose.

I was looking at a Honda petrol powered pump 2nd hand for $600. The only issue with that is I'd need a lot of hose to get the water where I want it. Probably a more long term solution (right now there's a traffic jam with the kids cars in the way).
