the irrigation pump strikes again

ref thread1528-403682: priming an irrigation pump

I know a lot more about priming pumps than I did (fill pump with it switched off, do the priming plug up fairly tight, run the pump until it stops bubbling, tighten the plug fully).

So, in almost a repeat of last year, but 2 weeks earlier, I decided to repair an annoying leak in the suction hose. I then celebrated by irrigating the vegetable patch and the flower garden, but was mystified to see that the header tank ran out, even though the pump was running. Wandered down to the pumphouse expecting to find my repair had crapped out. No. So I looked in the creek. Empty.

So, no more creek water this year

Are you asking for a solution or just sharing?
Do your Abos have any ceremonies similar to the rain dance of our plains Indians?
Cloud seeding?
I don't know.

RE: the irrigation pump strikes again

We're headed right back into another drought with less than 1/2 our normal rain and the snow pack at less than 1/3. It's creepy to see the guy with the snow depth gauge standing in a field of dry grass..

They say it's another of the high pressure walls set up over the Pacific.

I've often wondered what would happen to that high if you set up a couple of 5MW fans in strategic places to blow up into the high. Would that influence things or be a classical mosquito-fart-in-a-hurricane type situation?

RE: the irrigation pump strikes again

Reminds me of a rip-off micro-hydro installation I saw years ago.
This was a small plant installed for an isolated indian reservation. I wasn't involved professionally, but I had friends living there.
The load control was somewhat unique.
A large water tank bristling with heating elements.
The generator was intended to run at full load at all times. The governor, instead of controlling the water flow, switched on more heating elements to burn up the excess power. Part of the project was a new laundromat to use all the "free" hot water.
Problem #1. The set was badly undersized for the community. They suffered chronic low voltage and under-frequency.
There never was a usable amount of hot water for the new laundromat.
I dropped into the city offices of the design and build firm for a friendly chat.
"I was wondering how you sized the set?"
"Well, the Department of Indian Affairs requires a full engineering study for any installation over 50 kW, so we put in a 50 kW set to avoid doing a full study."

Did I mention that when I was shown the installation on site, the turbine was bone dry and stationary?
They were running on the diesel backup. No fuel delivery was available in the remote location, the band had to buy a truck to fetch their diesel fuel.
Of course still low voltage and under frequency and still no hot water. Too expensive to heat water with a diesel set.
An elder sadly commented;
"If they would have asked us we could have told them that creek goes dry all summer every year."
A typical DIA rip-off. Incompetents giving tax money to incompetents and the government can show on paper that they are doing good things for the natives.
