New water well

[Steppenwolfe]

Just had my first experience with drilling a new water well. Pretty amazing piece of equipment to watch. Took about 12 hours to hit 620 ft. According to my driller we have right at 4 gal/minute replenish rate, a 570ft head of water with the pump sitting at 585; this gives us an 800 gal reservoir in the well. 4 gal/min doesn't sound like a lot, but with reserve we should have more than enough for two people. We have a spring house as well on the property, but I don't have power to it yet.

Hope your pump lasts as long as ours did at 34 years. Hope you can get a brushless pump now. Never thought to ask the guy when he installed our new one recently (in less than 2 hours' time).

About to start drilling my new well in a couple weeks. Expensive endeavor no doubt.

I always thought 4 to 5 gal/min was a good average. It's the reserve that is important. Am I wrong?

I don't see a slush pit, so must have drilled with air. Air drilling can go quickly if they don't hit anything very hard. 4 GPM is 5,760 gallons per day. As long as you have adequate storage 4 GPM can supply 10 or more houses. A good water well is one of the best investments a person can make.

Regular submersible motors do not have brushes. The brushless thing is for variable speed pumps, which you want to stay away from if you want something dependable and long lasting.

drilling that deep, you might need a water softener, ever since my water company drilled to 1000 feet,(to avoid chemicals used in aircraft manufacturing) my water got hard, and it takes 3X longer to cook something in water!!.. that REALLY sucks!!..

According to my driller you are correct; he said he has wells in the NC piedmont that only produce 1/2 to 2 gpm and work fine because of the high reserve in the well.

My well supplies, I was told, about 14 gal a minute and is almost not enough due to being very little reserve. It supplies the water for the house and an open loop geo heat pump. I really think it may be only about 12 gpm.

Four or five gpm is adequate for a single family house. Unless you plan to water the north 40. I've seen MANY wells - 600 to 800 - and produce 1 gpm. Storage is the key.

If you have enough water for an open loop geo system, you have a lot of water. What you may not have is enough water to feed both the geo system and house at the same time. If geo uses 10 GPM and house is needing 5 GPM, your 14 GPM well pump is lacking. However, there are ways to supply both in series instead of parallel, and use only 10 GPM total. The house supply would come off the back side of the Geo instead of the front side. The temp of your house water will change about 10 degrees up or down as the Geo system is working. You won't notice the temperature change nearly as much as the higher pressure in the shower from having adequate water supply for both.
