Gushing is good!

Gushing water hose after pump priming

A gushing water hose—nothing more normal and mundane wherever electricity for pressurized pumping, and of course WATER, are in plentiful supply. This tiny farm is in such a place, yet this gushing hose signals something much happier, an elevated event, because it’s proof positive that the dug well that irrigates the field is back in action once again after another frozen winter. Priming the pump is usually a mid-May thing, when freezing is over. The operation is simple enough: slowly pour a couple of gallons of water into the pump so it backfills the pipe that goes into the well, turn on the pump, and wait for it to catch. It may take two or three top-ups and retries. When water gushes, the pump is primed for the season! It’s not foolproof, though, the pipe could’ve gotten hopeless clogged, the well-used and dilapidated pump and tank could decide to give up a seal or conk out entirely. Then the simple would become usually costly repairs or replacements. But not this time!

If the irrigation fittings look small, they are indeed. I’ve seen photos of irrigation set-ups on big farms that are full scale waterworks, with orderly grids of giant pipes. Here, the setup is a 1″ plastic pipe that snakes above-ground out into the field—it’s the disconnected part on the left. The pipe can be this small because it’s only meant for supplemental low-pressure drip irrigation: not every day, not all crops all the time. And, a dug well like this doesn’t have an endless water supply, you don’t want to get ahead of its reservoir size and replenishment rate. So drip irrigation by section is the max use case, although hand watering, filling up barrels, and the occasional sprinklers can all be deployed in a pinch. Overall, 1″ is fine for a slow, steady drip!
