Are Shallow Wells Bad?

How much does it cost to dig a shallow well?

Most well drillers also have a minimum charge, usually around 100ft minimum which at $45 per foot would be $4500.

Drilling a water well is a long term investment and most people are reluctant to drill without knowing if they will find water, and if so at what depth..

Is well water better than city water?

Well water typically tastes better due to the lack of added chemicals (ask anyone). Public water is treated with chlorine, fluoride, and other harsh and dangerous chemicals. Well water travels straight up from the ground; you get all the health benefits of clean water with none of the harsh chemical additives.

Can you drill an existing well deeper?

Well Deepening: Reentering an existing well and drilling to a deeper reservoir. Well deepening is re-drilling into an already existing well in order to find a deeper more productive reservoir. Sometimes a previously unproductive well can be deepened in order to reach a location with higher flow and temperature.

Why do wells fail?

Similar to well siting, there are a number of factors in the drilling process that can cause water wells to fail in the near-term. These include the depth of the well, the depth of the hand-pump, the placement and quality of the materials, and more. Groundwater fluctuates with the seasons.

How do shallow wells work?

Very shallow wells (less than 20 feet) can use a suction pump at the ground surface. Deeper wells must use a submersible pump to push the water to the surface. Ground water is allowed to enter the casing by either an open end pipe, perforated pipe or a well screen, depending on the size of the aquifer soil particles.

How deep should a shallow well be?

Dug wells have a large diameter, are shallow (approximately 10 to 30 feet deep) and are not cased continuously. Driven wells are constructed by driving pipe into the ground. Driven wells are cased continuously and shallow (approximately 30 to 50 feet deep).

How long do wells last?

30-50 yearsThe average lifespan of a well is 30-50 years, although they can last longer or shorter depending on different circumstances. If the well you are buying is over 20 years old, you should at least factor in replacing the parts that commonly fail into your home buying budget.

Does rain fill your well?

YES! Rainfall has a direct impact on the local water table, which may immediately impact your residential well if it is supplied by shallow aquifers. … Your well may not ‘fill up’ when it rains, but it does reap the indirect benefits.

How do I find the water table in my area?

How to Find My Water TableCall your local County Extension Office. It may have statistics for the average annual water table level in your area. … Look online. Check out the website for your local Water Resources Office. … Dig. This is the most reliable way to find the water table level on your land.

Do shallow wells go dry?

Wells typically do not go dry all at once. Rather, they slowly get worse due to lack of recharge. Often older wells that were drilled only into the top of an aquifer and did not penetrate the full thickness of the aquifer are the wells most likely to fail first.

What is considered a shallow well?

What Is a Shallow Well? If you have a shallow well, it means that your water source is relatively close to the ground’s surface. Your local water well drillers will measure the water table and calculate to what depth the well should be dug. … You’ll need a shallow well pump for wells of 25 feet or less.

How Far Should a well be from a house?

10 feetWells in most jurisdictions are at least 10 feet from the property line. That would mean that your well and your neighbour’s well would be at least 20 feet apart. That distance might not prevent your neighbor’s well from tapping right into your well’s aquifer and water supply and thus reducing your well’s flow rate.

How do I know if my well is deep or shallow?

If it is small diameter, such as 1-1/4” PVC, that would indicate it is a shallow “well point” as they are called. If it is 2″ or above, it very well could be a deep well. Larger casings may also be shallow wells. Some of the largest diameter wells are very shallow (bored wells).

How far will a shallow well pump push water?

The shallow well jet pumps draw water from one line situated in wells no deeper than a maximum of 25 feet deep. Deep well jet pumps use two lines, one for pulling the water, and one for pushing the water into the delivery system. Deep well jet pumps can pump water from wells that range from 25 to 110 feet deep.

Is a deep well better than a shallow well?

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.
