That is a really hard question to answer because there are different kinds of pumps. It might be a poor producing well needs a new pump, so does that make it a bad well? I had a client go from 3 gals/min to 12 when they replaced their pump.

Most people like to see at least 12-15 gallons per minute in a four hour flow test in my area, but honestly in some of the more difficult water areas, 5 gallons per minute might be a great well, for that particular water vein. Anything over 30 in my area is considered a gusher of a well. You can have two acreage properties right across the street from each other and one will gush at 30 gals/min and the other will trickle in at 3. It just depends on what water vein you are in.

You need to focus on what is normal for your area.

There is a lot that would affect your well production. The big thing that you want to think about is your pump. If your pump is more efficient than you will be able to produce more faster. http://www.brewerwelldrillingswva.com/services.html

I definitely think that this depends on the well that you have. Generally, I think that most wells produce plenty of water. What are you asking this for, because that might help in getting the right answer. If you are really needing to know soon, it might be a good idea to get someone to come look at your well. Then they should be able to tell you the most accurately so that you will know how much water your well produces! http://www.valleypumpco.com/services

The amount you are planning to draw from the well will be a factor in that answer. Making sure you know that will help you be able to decide what kind of system and pump you will need. Some people need to draw water for a longer period of time then others. I think that will be one of the biggest things you need to consider.

There are so many different answers for what youj ust asked. The well flow is tested over a 4 hr period - the state recommends an open flow to see what a well will really do. Different needs for different people require less or more gallons per minute but an ok amount may start at 3 gpm and go to 30 gpm....you would never be able to use a huge producing well like that for house use though.

I think it depends on what kind of well pump you get. I would call the company that sells well pumps to see what their ratio is. They will probably be able to help you the most. Good luck and I hope you figure everything out! http://www.twstanleywellpump.com/chatham-county.html

For FHA and USDA financing: a pump test indicating a flow of at least 3-5 gallons per minute supply for an existing well, and 5 gallons per minute for a new well. (this is a 4 hour test I believe) Properties with low flows typically have large storage tanks as well.
