How to pump out a 10,000 litre poly tank.

[CharlieBear62]

I purchased a cheap 10,000 litre poly rain water tank that has a slow leak at the outlet.

I want to relocate the tank and install a new outlet but it has about 10cms deep of water in the tank which makes it impossible to move by towing it with my Subaru Outback.

I was thinking if I was to attach a length of pvc electrical pipe onto a 12mm Hills garden hose connected to a 2 tap Davey pumps would that setup have enough grunt to suck out the water.

Maybe someone else has an easy solution to removing the water.
