How about a Clarke PW2 2inch Petrol Driven Water Pump - £200 from Machine
Mart. Pumps 400L per minute (probably half that in real life). Add a
few 1000 Litre IBC containers (£20 each on ebay - 280679272487), and some
jerry-rigged piping, and you've got ample water where you need it.

Those pumps are a bit of a pain for that sort of thing - heavy, as are
the pipes, and priming requires more effort than you want for a little
bit of water.

Nobody (least of all the OP) commented on my idea of connecting a hose
from the Council-installed handpump to the allotment. Of course we
haven't seen the precise scenario, but this would seem to me to be
easiest, by far
