When, Sant Sebastià is resettled, the spring would be built up to have bigger more effective reservoir. A solar powered pump would patiently lift the water up to the village’s cisterns during the day. Probably, these cisterns would also be augmented with rainwater catchment and redeveloping the other spring on the other slope. The water from the spring is quite a bit. I estimate maybe 6 cubic centimeters a second …. this is just a rough calculation … approximately 518,400 cubic cm a day, a little more than 500 liters a day. Not a lot of water, but maybe enough for a small settlement – at least for drinking and cooking.
