I'm moving to a place in the north of Portugal to start my own business as a market gardener, have been having troubles on finding info on how to calculate the irrigation system. My idea idea is to create a well, which should be 80m deep, pump water to deposit on the top of the property, and then supply the garden (24 beds of 0,75*30m) by gravity as much as possible.

What kind of pump is needed, pipes and water deposits needed? I'm on a budget so learn how to and do it by my own is essential.

Thanks in advance,
