hello to all who might have recommendations, ideas, or who might want to learn from this discussion.
Earlier this spring we hand-dug a 10m deep well at the highest elevation of the site to have easy water access for future projects on a sandy farmland on the southern, sunny part of germany, in a hope that we can transform this land to our little paradise.
soon after the well was done and tested, we have planted 15 fruit/nut trees staked, mulched, and more to come.
Right now we are about to set up an expandable drip irrigation system, and thats where advice comes in really handy.
first round to water the trees ASAP, as for now we are watering them by hand, second circuit for a vegetable garden next year.
the trees are scattered on the "edible hedge zone" of our land, that is about 100 meters long.
we could lift a 1000l water tank (that needs to be refilled with a small electric pump periodically) about 2 meters from ground level, use a 100 m 1/2 inch distribution tubing with 1/4 inch branches and reducer tees, and multiple adjustable emitters (these ones: https://www.amazon.com/dp/B07173Y5KD/ref=sspa_dk_detail_3?psc=1&pd_rd_i=B07173Y5KD&pd_rd_wg=82AT2&pd_rd_r=KZKTVE7BE2RBZAS2X8T8&pd_rd_w=3MKNk
) for each tree.
im about to build this system described, then adjust each emitter so they emit the same amount of water in a given time (open more the ones that are further away from the tank, taking less pressure), then every time fill up the tank with the amount of water needed, and let it flow down in the system, no matter how long it takes. so far more like build, test, and then see the GPH, instead of knowing what flow rate I need and design accordingly.
this setup means very little water pressure, still without experience on the field I think its possible. what do you think?
I basically need advice here from people of experience in low pressure, gravity fed drip irrigation, to understand if this idea makes sense at all, if this setup is in fact would be able to bring the water so far from the source, If it could provide sufficient water for the trees, and for future veggie garden areas.
I know with more elevation comes more pressure, yet not only our resources are limited, we also face local law restirictions - we can not lift the container higher.
thanks for all ideas, recommendations and advice.
