How many gallons a day can a well produce?

A well's daily production varies dramatically, from less than 1 gallon per minute (GPM) for low-yield wells to hundreds of GPM for high-yield wells, meaning a small well might produce ~1,440 gallons daily (1 GPM x 1440 mins) while a larger one could supply thousands, but it must meet peak demand, typically requiring at least 1 GPM for domestic use and 500 gallons in a 2-hour peak period, often needing storage tanks to buffer usage.


How much water can a well produce in 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 should a well produce?

The Water Well Board and the New Hampshire Water Well Association, a group of private professionals associated with the well water industry, both recommend a flow rate of 4 gallons per minute for a 4 hour period. That's equivalent to 960 gallons of water flowing steadily for 4 hours.


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.

What is the maximum yield of a well?

Maximum safe yield is measured by pumping the well for an extended time and also measuring the groundwater level in the well. The amount pumped out of the well and the amount going into the well from the surrounding groundwater need to balance, or the well will “run dry.”


How to Find Well Water Depth



What is considered a high producing well?

Many wells produce less than about 15 BOE per day and are considered low-producing or marginal. A significant number of wells fall between roughly 15 and 100 BOE per day. A small top tier of wells produces more than 100 BOE per day and can account for a disproportionately large share of total output.

How much does it cost to dig a 20 ft well?

Drilling a residential water well costs $25 to $65 per foot or $3,750 to $15,300 on average for a complete system and installation. Prices include the drilling, a pump, casing, wiring, and more.

How quickly does a well refill?

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.
 


How many years does well water last?

A well's lifespan is considered to be roughly 20 to 30 years. Over time, yield may decline because of sediment or mineral scale build-up. For some homeowners, however, a well can last many years beyond this lifespan.

Can you run water when power is out with a well?

Most well pumps are powered by electricity, meaning water won't flow when there's an outage. (But some wells still include one or more holding tanks that can supply water in the meantime. These tanks usually hold between 10-50 gallons of water.)

How much rain does it take to replenish a well?

Even for an aquifer in close contact with the surface, a well will not recover after just one rainfall event. It takes several slow, soaking rains for the water to filter through the ground. Shallower wells may see their water levels rise more quickly with a return of rain.


Can I fill a 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.

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.

How often should a well be flushed?

It is generally recommended to flush your well at least once a year. Regular well flushing helps maintain the quality and performance of your well system. Over time, sediment, minerals, bacteria, and other contaminants can accumulate in the well, affecting water quality and reducing the well's efficiency.

What's the average cost to replace a well pump?

Most well pump replacement projects fall between $975 and $2,575, but many factors can add additional costs. A small hand pump can cost as little as $200, while a high-end constant-pressure well pump could set you back as much as $5,000.


Can a new well increase property value?

Increased Property Value

Adding a private well to a property can increase its value and appeal, especially in regions where water availability is a concern. Prospective buyers often see a private well as a valuable addition, knowing they have a stable water source without reliance on municipal systems.

What happens if a well runs dry overnight?

In most wells, the pump is located within the well underwater, known as a submersible pump. When water is drawn down below the pump level, the pump will bring air into the system instead of water. Calling in a professional to measure the water depth and lower the pump can quickly fix this problem.

How much hot water does a 20 minute shower use?

How much water you use during a 20-minute shower will depend on what type of shower system – and in particular, showerhead – you have installed. Low-flow showerheads will emit around two gallons of water per minute, equating to 20 gallons per 10-minute shower, and 40 gallons over the course of a 20-minute shower.


Is it okay to buy a house with well water?

Overall, it's important to get all of the facts before purchasing a home that uses well water. While well water is completely safe to use and drink, you should know any potential problems, regulations with well drilling and testing, and how to properly treat the water before making a purchase.

Is there a monthly bill for well water?

One benefit of installing your own well is that you'll no longer need to pay municipal water bills. You'll only need to pay for the electricity to operate the pump (about $3–$4 per month), plus maintenance costs of $100–$250 per year. Compared to a monthly utility bill of $20–$40, you can save up to $500 a year.

How deep is too deep for a water well?

Deep wells can be anywhere from 100 to 1,000 feet deep to access water reserves. If you need a deep well, factors like water table levels, water quality, and the intended use of the water source are all considered to determine the proper depth.


How do wells impact property value?

The existence of a well on a property can influence its resale value and insurance considerations. Properties with well-maintained, high-quality, and reliable wells are likely to be more desirable and can attract a premium. However, poorly maintained wells might reduce property value or increase insurance costs.
