The council have decided to cutoff mains water supply to our garden
allotments. In place they have drilled several deep holes into the
water table and put manual pumps atop each well-hole.

Problem now is getting water to the plants.

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.
