I am installing a raised bed, 8'x40', and want to use a drip system consisting of 6 to 8 branches 40' long. The recommended operating pressure of the drip system is 8psi. My water source is a ditch that is 50' horizontal and 15' head. How can I feed the drip system? I was thinking gravity tank at 10 feet, but that just gives me 5psi before piping. And I was looking at a 1/2 hp pump, but it's minimum operating pressure is > 20 psi.
