How often do you need to drill a new well?

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.

How do you know if you need a new well drilled?

How long do new wells last?

The average lifespan for a well is 30–50 years. 2. How deep is the well? Drilled wells typically go down 100 feet or more.

How often should a well be maintained?

Wells should be checked and tested ANNUALLY for mechanical problems, cleanliness, and the presence of certain contaminants, such as coliform bacteria, nitrates/nitrites, and any other contaminants of local concern, (for example, arsenic and radon).

Can an existing water well be drilled deeper?

Can I deepen my existing water well? Before you can deepen your well, It is essential for your well driller to have complete information on existing well. Including, depth, pump location, feet of pipe. Because regulation was not a strict in the past, there may be no information recorded on your old well.

WELL DRILLING 101 | Every Step Explained

Do deeper wells mean better water?

Water quality in a deep well usually changes more slowly than in a shallow well. That's because groundwater does some mixing as it moves through the aquifer. A spill a mile away from your deep well in the Basin and Range aquifer might be substantially diluted with clean aquifer water before it gets to your well.

How deep should a well be for drinking water?

For drinking water wells it's best to be at least 100 feet deep so that surface contaminants cannot enter the well. The average well depth for private homes is between 100 to 800 feet [2]. You may need a deeper or shallower well if your area has different geology than another region of the country.

Do wells need to be cleaned?

Following are some signs that may indicate a need to clean your well system. The well water is turbid, which means it is cloudy or has suspended matter in it. There has been a decrease in the well's capacity—that is, the gallons of water per minute that the pump can supply to the system.

How do wells replenish?

A well replenishes itself by drawing water from the underground aquifer. Other sources with which a well may replenish itself include rain, lake or river water seeps into the ground to refill the aquifer from which the well is drawing water, and snowmelt.

Is well water hard to maintain?

Well Water is Usually Hard

Because water is an incredible solvent, groundwater will dissolve organic matter, including minerals found in the soil and rocks beneath the Earth's surface. The minerals calcium and magnesium are what make well water hard.

How do you maintain a well?

Keep hazardous chemicals, such as paint, fertilizer, pesticides and motor oil away from your well. Periodically check the well cover or well cap on top of the casing (well) to ensure it is in good repair. Always maintain proper separation between your well and buildings, waste systems, or chemical storage facilities.

Do wells run out of water?

Well water will run out if the groundwater level drops below the water intake depth. This can be caused by natural or man-made variations in groundwater height including reduced precipitation, slow groundwater recharge, well infill, high water usage, well drawdown or hydrofracking.

When should I replace my well water?

How much does it cost to drill an existing well deeper?

The average cost to redrill a well deeper is $3,000 to $6,000, or between $35 and $84 per foot, which is the same as drilling a new well. Hydrofracturing is another method used to increase water flow and costs $1,500 to $3,000. Explore both options before drilling.

How do I know if my well water is running out?

If you get your water from a private well, there are some warning signs that your well may be going dry. The first sign is the water is sputtering out of the tap, indicating air pockets in the well. The second sign is the water is not clear, but muddy or filled with sediment.

How can I tell how much water is in my well?

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 indicate the exact water level.

Is it safe to drink water from a well?

Yes, as a private well owner, you are responsible for testing your well to ensure the water is safe to drink. EPA is responsible for making sure that the public water supply within the United States is safe. However, EPA does not monitor or treat private well drinking water.

How many gallons is an average well?

The typical 6-inch diameter well will hold approximately 1.5 gallons of water per foot of casing. The height of the water above the pump when it is not operating, multiplied by the gallons of water per foot of casing approximates the amount of available storage within the well casing.

How do you know if your well is bad?

Why do wells fail?

If a well is drilled at too shallow a depth to save on expenses, communities whose well produced enough water during the rainy season will struggle to pump enough water when the water table drops during the dry season. Low quality or improper construction materials can also cause the well to fail early on.

How long can you run your hose on a well?

How Long Is It Safe To Run A Well? This depends on which submersible pump you use. The majority of people are fine with continuous running, but there are limitations which prohibit usurers, but some have limits of “run for less than 2 hours” or “leave to cool down after 30 minutes”.

How far away from your house can your well be?

Some activities legally require more than a 50-foot zone of protection. As a general guidance, personal drinking water wells should have a minimum horizontal distance of at least 10 feet and preferably 25 feet from such boundaries.

How do well drillers know when they hit water?

Announcing when you hit water is a bit confusing. With a drill stem big enough for three air blowers, there is a huge air compressor on the rig.As each cuttings is moved out of the hole through the repulsion of air, it pushes up into the hole in strong enough force.

How deep is a household well?

Most household water wells range from 100 to 800 feet deep, but a few are over 1,000 feet deep. Well yields can be increased by fracturing the bedrock immediately around the drill hole and intercepted rock faults.

Is 6 gallons per minute a good well?

CALCULATING A WATER WELL'S FLOW RATE

The average American household needs 100 to 120 gallons per person per day, and a flow rate of about 6 to 12 gallons per minute. This requirement may be higher if it serves a home housing a large family or there are large water demands.
