The tote that I was referring to looks like
this. You could get an electric dewatering pump that'll run off the generator and hook a garden hose to it, although @ 150' there will be considerable water flow loss due to friction. Or, you could go a step bigger and get a 1/2 hp electric water pump. Hook it up to 2" PVC (buried or laying on top of the ground) and run that to the garden, tapping off of it with a hose.
Or, use the dewatering pump to fill up the tote and wheel it to the garden. They normally have a 2" butterfly valve built into the tanks. If you go that route, make sure that the tanks can be cleaned out good enough for use on stuff that you're going to eat. 275G of water = roughly 2291# tho.....
Dad waters his property at the lake with a 1 hp pump (220v) that sucks lake water. We put in a 2" trunk line and ran 1" branches off of that, stepping down to 3/4 at the sprinkler head. He can run 11 impulse sprinklers at once without any apparent loss of flow.
