- Off-grid growers and water-system builders
- Worth noticing
- The plans cover eight pump sizes, but the site says only its 1½-inch plan is field-built so far.
Field notes
The calculator includes inputs for drive-pipe material, supply-line length, standpipe height, and delivery-pipe dimensions, then accounts for supply-line friction in its usable-fall estimate. A separate planner compares estimated output with entered garden or livestock needs; the page gives example daily water figures for cattle, horses, and goats. Users can save their inputs as a link or print a site report.
