I've consulted the Oracle - he's a Chartered Geologist who does this sort of thing for a living.
The preferred options are as follows:-
Dig a sump at one end, pump it out and fill up with concrete.
Pour concrete into one end to push the water along. Bail out the crap - his words - at the other end and fill up.
If there's only a small amount of water fill it up with the concrete a bit on the dry side.
If the water has sat there for some time you're in trouble 'cause the bottom and sides will be soft and you should go deeper to get to some solid ground.
He's probably being a bit pessimistic 'cause the NHBC isn't going to come and inspect yours
