If you're not paying for it, automatic is great. The fact remains that once you go automatic, it's not "just the pump" the owner is buying, but the increased electrical feed, genset if required, additional maintenance, possible secondary utility feed from an adjacent electric grid. Diesel can be cheeper in the long run, but still has it's own issues. The cost add up quick. I've got some numbers from a case study on pumps, electric vs diesel at the office I can forward if you want. Bottom line, keep it simple, if it works with no pump, awesome. If not, add the pump and reduce the pipe size.
