Low Yield or Low Flow Well? Explaining Options To Use a Low Producing Water Well
Вставка
- Опубліковано 3 чер 2018
- I cover a topic I wish I didn't have to address and that is a low flow and low yield well. This generally refers to wells less than 2 gallons per minute (gpm). Although a low flow well isn't ideal, there are options out there to make these systems work and utilize what you have besides abandoning the well and not using it at all.

Thank you for another great video. I had a question about a deep, low producing well. Our static water level is 350' in a 700' deep well, but the well driller noted only 1 GPM. So we'll be installing a cistern to hold water. We've gotten two quotes for the well pump, with very different recommendations. The first bid recommended we only pump at the replenishment rate of the well, so it doesn't run dry, and to better protect the well itself. The second bid said that restricting the pump to 1-2 GPM, when there's 500 gallons of water putting pressure on the pump, puts a lot of unneeded stress on the pump. He recommended a pump that will do 8 GPM when the well is recovered, slowing to 2 GPM before a pump tech would turn off the pump so it didn't run dry. He didn't see any problem with drawing the well down so far and letting it recover.
So it sounds like option 1 trades pump life for well life - more strain on the pump to restrict flow, but the well stays full. Option 2 will pump out much of the well quickly, but not put undue pressure on the pump. Do you have any thoughts one way or the other on running a well like this mostly dry? (In reality if the cistern calls for water at 300 gallons, the well would always have 500 - 300 = 200 gallons left.)
Thanks for any thoughts!
I pounded down a 15 foot 2 inch point well. It flows around 3 gallons a minute 18" above ground. I am happy just to have clean water at camp. I use a ram pump to pump it half way up the hill.
How much room below the pump should I leave on my well? I am running into air bubbles after a little while of watering my garden. I’m thinking there might be some room they left below the pump. Maybe.
Great video, makes me a lot less worried about my setup but wanted to ask your opinion. I got a 250ft well in a mountain setting. When the well was drilled in the 80s they rated it as 2.5gpm. when they did it they setup a 300 gallon holding tank and the pressure tank is quite sizable too, not sure exactly how big. Big thing is they have a jet pump that is as loud as all get out next to the pressure tank, inside the house. In this type of setup do you think that jet pump is actually pulling water out of the well or do you need a pump between a holding tank and the pressure tank to provide adequate pressure and maybe there is a submersible used as the source for the holing tank? If so anyway to cut down on the noise? This jet pump is huge and seems like it might be overkill for running pressure into a tank 3 ft away from source. Also you make 2.5gpm sound very not scary especially for a small house like mine (2bed max full time occupancy of 4 per the permit). Any potential I could cut the holding tank out of this scenario?
Question: how can you determine your well production rate? We have a 340 well....initially(for the first two days) there was only 23 ft of water in it. I came back about 12 days later....we hadn't received significant rain and there was 300 ft of water in it....but I don't know how fast it filled. There wasn't a pump placed in it...how can I drain or pump out the well to better monitor the production rate
I have a question, my well is 45 ft deep static 20 ft and 25 ft of water 6 inch metal casing, It was build by my grandfather in the 60s and never pumped,but always has water never went dry,my question is will I have plenty of water for a pond that's a 30 ft by 40 ft 4 1/2 ft deep,I bought a submersible 1/2 hp 2 wire 12gpm pump I live in South Texas thanks
When do you recommend options in the video? It ended. Still waiting.
Ok I just had a well drilled. He hit ground water at 9 feet. It's ground water low level. I don't need drinking water. He hit some kind of gray something at 50 feet. Told me below that is gray something makes the water taste bad. Should I go deeper? Can they know the area and know what the odds are of hitting good water source at 100 or more feet? Supposed to be good driller. 3 gpm at 50ft they are testing quality now. Just drilled
I just drilled my well. Went to 197’ and I’m getting 1/2 gpm. Is there any chance the water production increases? I drilled it with a cable tool, and I had to cement through a couple of layers (I assume they are water bearing, as they were unconsolidated and kept sluffing in on me). I’m hoping the well continues to develop. Any thoughts? I’m in Oregon, and I was in rock from 18’ all the way down.
Is ot low yeild or does the pump guy just put in the pump that will never draw the well down, so is it a weak pump. Or the production zone? Of someone draws a well down fast, wont it clog w fines? Good video video.
Very useful. Great information. I'd like the camera to be closer though.
Please describe your ideal fix for the exact words you used here (1 gallon per minute 705') - 5:14-5:30......specifically best complete set-up to compensate? Thanks
Drew D What is this for a house well only? What is the static water level in that well?
Fracking might help? What is average fracking cost?
Just had one dug 350’ for 14k
My well 2gallons/ minute aorund first hour go down 1/4 gallon after 3 hour
