##### Asked by: Paul Pierceson

Roughly 1 inch thick, the typical well holds roughly six in inches in diameter. A 1-foot-wide casing gets **five gallons** of water per foot.

## How many gallons of water is in a 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 many gallons are in a foot of well casing?

1.5 gallons

How to Calculate the Gallons of Water per Foot of a Well Casing. We have about **1.5 gallons of water per foot of depth of a well** when we’re using a standard residential 6″ well casing. The height of water column inside the well and available to the pump is less than the total well depth.

## How many gallons does a deep well hold?

A standard 6-inch diameter drilled well can store **1.5 gallons of water per foot**.

## How many gallons per foot is 4 well?

## How many feet of water is in a well?

Drilling a Water Well for household use will usually range from about **100 feet to 500 feet** deep, but… When drilling a new well for your home or business, the depth of the well depends on the geology and underground water levels of the area.

## How many gallons does a 300 foot well hold?

For example, a 6-inch diameter well that is 300 feet deep contains **450 gallons** of water (300 ft. x 1.5 gallons/ft. = 450 gallons).

## How many gallons is a 50 foot well?

75 gallons

If the well currently holds 50 feet of water, the total water volume would be calculated as follows: 1.5 gal/ft x 50 ft = **75 gallons** total water volume.

## How long does it take well to refill?

Well water can replenish at a rate of **5 gallons per minute on average**, but it will vary. It depends on the age of your well, how long you’ve been using it, the well’s location or geology, and the aquifer the well taps into to replenish its water level.

## What is the average gpm for a well?

That said, a typical minimum acceptable well yield is **3 gallons per minute**; some lenders want to see 5 gpm; And some authorities will accept lower well yields, down to 2 gpm provided that 1,500 gallons or a similar quantity of on-site water storage is also provided.

## How do I calculate water volume in a well?

*Down volume is equal to pi multiplied by radius squared multiplied by hi. Or we could say the amount of water in your will.*

## How much water can a well produce per day?

1,440 gallons per day

A well’s water yield will change based on well screening equipment, alterations in subterranean rock formations, and water table variability. The required minimum yield in this area for a drilled well is 1 gallon per minute, or **1,440 gallons per day**.

## How much water can a 2 inch well produce?

50 gpm

**Some 2-inch wells are capable of pumping in excess of 50 gpm**, however, no 2-inch pumps are capable of 50 gpm. Therefore, wells often are drilled larger – not for more volume, but to accommodate the larger pump sizes.

## Can I fill my pool from my well?

As we said above, **you can fill your swimming pool or hot tub with well water**. In fact, it’s one of the least expensive options, especially compared to a pool water delivery service. Some people choose to fill their pools with city water or municipal water from their house, but not everyone has this option.
