Marv Hegge built a system at his little ranch in Oakland, OR (near Toby's
place) with a lowboy or two worth of remnant/blem sewer pipe. A saddle dam
had a sewer pipe well built into the middle of it, with a solar electric
pump sending water from there up to a hilltop sewer pipe "water tower". I
think the tower was 6' diameter at least, stacked up on end. Worked well, so
to speak.
