Hi there, I'm one of the owners of the property in question.
Rhys:
The solar powered pump on a timer was my first thought, but after looking around a bit, I can't find a solar pump setup that costs less than $700, which is out of our price range at the moment.
Definitely something that I want to have in the future, though. (The idea of re-purposing the old pump for the cistern is a great idea that hadn't occurred to me. Thanks!)
Dave:
The main issue is simply "How to have enough water to sustain roughly 1/8 acre of mixed vegetables between April and October."
Solutions being within the constraints of the only source of electricity on the property being a diesel generator that must be started and stopped manually, and the well is very slow and relatively shallow.
I'll try to get a useful map worked up later today.
Any help is welcome and appreciated
