How many gallons of water does a well hold?

A well's water capacity varies greatly but a standard 6-inch diameter well holds about 1.5 gallons of water per foot of depth, so a 100-foot deep well with water to the top would hold roughly 150 gallons, while a larger 10-inch well holds more, around 4 gallons per foot. The actual volume depends on the well's diameter, total depth, and the level of the water inside (the static water level), not just its total depth.

How much water is in a 100 ft well?

For example, a typical 6-inch diameter well with 100 feet of water in the borehole would store 147 gallons of water. If the 6-inch well were replaced with a 10-inch diameter well, the storage would increase dramatically to 408 gallons of water.

How much water can a well produce a day?

A well's daily production varies greatly, but common yields range from 1-20+ gallons per minute (GPM), meaning a well could produce anywhere from 1,440 gallons (at 1 GPM over 24 hrs) to over 28,800 gallons (at 20 GPM) per day, depending on local geology, depth, and diameter; a typical household needs around 300-600 gallons daily, often managed with a storage tank for low-yield wells. 

How many gallons of water are in a normal well?

A well's water storage capacity varies greatly by its diameter and the height of the water column, but a common 6-inch diameter well holds about 1.5 gallons per foot of water depth, meaning a well with 100 feet of water stores around 150 gallons. However, the yield (how much water it produces per minute) and aquifer recharge rate, not just storage, are crucial for a reliable supply, often requiring a storage tank for higher demand.
 

Can I fill my pool with well water?

Yes, you can fill a pool with well water, but it requires careful planning and treatment due to high mineral/metal content (iron, manganese) that can stain surfaces and cloud water, so testing the water first, using a hose-end filter or metal sequestrant, and monitoring your well's flow rate to avoid running it dry are essential steps for success.
 

How to calculate the amount of water you have in your well

How long can I run a well to fill up a pool?

Understanding Your Well's Capacity

Your well needs muscle to fill a pool. Most residential wells pump 5-20 gallons per minute. Sounds decent, right? But filling a 15,000-gallon pool at 10 GPM takes about 25 hours straight.

Will well water turn my pool green?

Metals in your pool water

When your pool water has high levels of copper or iron (common in well water) once you apply chlorine or other pool chemicals to it, you will see that it will turn green in absolutely no time.

Is it common to run out of water on a well?

But like other water resources, your well water can dry up if you fail to manage it properly or due to natural causes. Often, wells run out of water temporarily, and there are reasons this issue occurs.

Do deeper wells mean better water?

If you install a shallow well, your water quality will be most influ- enced by your activities and those of your neighbors. If you install a deeper well, your water quality will be influenced by land uses farther uphill from you in the groundwater flow system.

How fast does well water replenish?

Well water replenishment varies greatly, depending on the aquifer's size, geology, rainfall, and pumping rate, but it's a slow process involving water soaking through soil over weeks or months, not just a single rain event, with deep wells taking longer to recover than shallow ones. A healthy recovery rate is often 5-10 gallons per minute (GPM), but low-yield wells might only replenish at 0.5 GPM or less, requiring careful water management, or even a new well or tank system to meet demand.
 

Can you run out of well water in a drought?

Yes, certain wells—especially shallow or older ones—can run low or temporarily dry during drought. With demand management and professional upgrades, most homes maintain reliable service.

How much water does a 2 minute shower use?

Shower. Power or mixer showers: around 15 litres is used per minute. Electric shower: 6 litres is used per minute.

Is there a way to tell how full my well is?

Visually. One of the simplest ways to check the water level in your well is just to look down in the well casing to determine if you can see any water. In general, you can see the reflection of water up to around 50ft or so.

Can a deep well run out of water?

While well water can run out temporarily due to factors like aquifer depletion, seasonal variations, or inadequate well depth, proper management and maintenance can mitigate these risks.

How much does it cost to dig a 150 ft well?

An artesian well costs $35 to $85 per foot or $5,000 to $15,000 for drilling and casing to an average depth of 150 to 450 feet to hit an aquifer. Groundwater in aquifers between layers of rock is a pressurized body of water, causing water to flow naturally without pumping or electricity when tapped by a well.

Is 10 gallons a minute good for a well?

Yes, 10 GPM (gallons per minute) is generally considered very good for a residential well, as it comfortably supports an average family's needs, including multiple fixtures running simultaneously, with many wells in the 5-15 GPM range being sufficient for typical homes. While 5-10 GPM is often cited as good, 10 GPM provides a robust supply for larger households or moderate irrigation, exceeding minimum requirements and offering ample capacity for modern water use. 

Do you pay a water bill if you have a well?

No water bill: You can use as much water as you'd like and never have to worry about a bill when using a private well. The only reason you'd pay is if you're using city water for wastewater (such as showering, flushing the toilet, etc…), although you can install a septic tank to avoid these costs.

What is the downside of having well water?

Potential contamination: Well water can be contaminated by chemicals, fertilizer, animal manure, detergent, sewage, and runoff from farms. These pollutants can impact the quality of well water and increase the risk of long-term diseases if high levels of contaminated water are consumed for many years.

How cold is deep well water?

So just how cold is well water? Typically, well water maintains a steady temperature year-round due to its underground source. This can range anywhere from 45°F to 55°F (about 7°C to 13°C), depending largely on geographical location and depth of the aquifer.

Does homeowners insurance cover well going dry?

No, standard homeowners insurance generally does not cover a well going dry from natural causes (drought, low water table) or lack of maintenance, as it's considered a gradual issue, not a sudden covered event like a burst pipe or lightning strike. However, it might cover well pump damage if a covered peril (like a storm, fire, or lightning) caused the failure, but not for age, wear-and-tear, or general breakdown. You can often buy separate endorsements or home warranties for mechanical failures.
 

How long will a well last without rain?

Deeper wells tend to withstand a drought with no problems. But if your well is affected, it can take several months of adequate rain or snow to restore the supply.

What happens to well water when power goes out?

Does Well Water Still Work When the Power Is Out? If you have well water, you will likely be unable to use your well water during a power outage. Well pumps are almost always powered by electricity, which means that when the power's out, no water will flow.

Why is my pool clear but slimy?

A slippery or slimy feel to some or all of the surface of your pool is a sure sign that your pool water is out of balance. Specifically, it means that your pool water is low on chlorine. When the chlorine levels in your pool water are low, algae will start to grow.

How to get a well water pool clear?

If your water test shows low — or no — chlorine levels, and your pool is cloudy, treat your pool water with a chlorine-based pool shock. This family of shock includes cal-hypo (calcium hypochlorite) or dichlor (sodium dichloro-s-triazinetrione).

Why is my pool still green after I tried everything?

If your pool is green and cloudy, it's likely an algae problem. Algae can persist in a pool even after shocking. A green pool – especially one that turned green overnight or after rain, can also be from a pool pump that isn't properly circulating water or an issue with your filtering system.
