In general, you should expect your well to replenish at a rate of 5 gallons per minute, but there are a number of factors that will play a role in how quickly it refills. For reference, if your well is 1200 gallons, it should take approximately 4 hours to refill.
A well is more than a hole in the ground. It's a complex network of parts, including well components and the geological features of the rock from which we draw water. The recharge rate for residential wells averages five gallons per minute. If yours can't keep up, it could be a bad sign.
It shouldn't take longer than 3-5 minutes for a well pump to fill the pressure tank. If it takes longer, you may experience a noticeable drop in water pressure, which would explain why your showers now take forever.
If you have a smaller-sized pool, using well water may be a good choice. But if you have a large pool and your well does not produce water quickly, it can take days or weeks to generate enough water.
A well is said to have gone dry when water levels drop below a pump intake. This does not mean that a dry well will never have water in it again, as the water level may come back through time as recharge increases.
It's a common misconception that rain has a direct impact on the amount of water in residential wells. Over 95% of rainfall doesn't go directly into your well or even stay on your property; it runs off into creeks, streams, and rivers, some of which become part of the area's surface water supplies, or “reservoirs”.
When a well “runs dry” it doesn't mean that the well will never produce water again. Aquifers can recharge through a combination of more precipitation and less pumps pulling water out of that aquifer. Sometimes wells can run dry permanently, but that is quite uncommon.
You can measure the depth of water by lowering a wetted steel tape to into the well until the lower part of the tape is under water. A chalk coating on the last few feet of tape indicates the exact water level.
Pumps should not run longer for 1 or 2 minutes. The reason is this could cause motor damage.
The average garden hose pumps out 8 to 9 gallons of water per minute (though it can vary from 4 to 12 gallons). If you're wondering how long it takes to fill up a pool with a garden hose, it takes anywhere from 24 to 48 hours to fill an average-sized pool. Of course, this is just an estimate.
The tanks should be flushed semi-annually to remove accumulated sediments by opening the tank drain valve. These sediments could harbor and shield harmful microbes from chlorination should the well and home plumbing system require disinfection.
If the well casing can be pulled, the hole should fill naturally with native material, and no further work is required. However, if the casing cannot be pulled, a certified professional water well contractor's services will be required to grout the well properly.
This can be caused by an aging well pump wearing out, clogged well screens, a partially stuck check valve, a broken well pipe, or a corroded well pipe. For well water problems, it's best to consult a well-professional. We recommend the national groundwater association, www.wellowner.org, to locate one in your area.
If you are mildly dehydrated, you may start to feel better within 30 minutes to an hour after drinking fluids. However, it takes several hours for your body to fully rehydrate and for symptoms like thirst and fatigue to completely resolve. Moderate dehydration typically takes several hours to a day.
First, up to 20% of wells around the world extend no more than 16 feet (5 meters) below the water table. That means these wells will run dry if groundwater levels decline by just a few feet.
The average cost to replace a well pump is $1,889, but most spend between $974 to $2,813 depending on the pump size you need.
A typical garden hose flow rate is usually between 9 and 17 gallons per minute. The average garden hose GPM would be around 12 to 13, but this can vary depending on the type of hose.
Narrowing in on the well dry problem
You can conduct this test yourself by measuring how much water flows from the faucet in one minute. If there is a significant drop between the original flow rate and the rate today, the low water level could be a culprit.
The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.
The quality of your water depends on several factors including geology and water levels. In order to allow for maximum ground filtration to remove impurities, your well depth should be at least 100 feet. As a general rule, the deeper you drill, it's more likely that there will be minerals present.

Natural Salts and Minerals. It should go without saying that, because well water comes from underground supplies, it is rich in many different minerals, including natural salts, calcium, iron and other minerals that will build up on the system. As minerals and salts build up, they obstruct the entire system gradually.
Adding water to your well is not recommended. It could contaminate your supply, and will not alleviate your water shortage problems during drought conditions.
