The following is a list of the variables that
can affect the production or the quantity of water that a well may be able
to provide.
- The type of soil that the well goes
through. The less porous the soils are, the slower the ground water will
travel to get to the well, even if there is adequate supply.
- The availability of an aquifer in the area
of the well. Higher elevations will typically have less available ground
water. You may find water at 40', but have to drill 400 or more to be
able to accumulate and store an adequate amount of water.
- The weather impacts the amount of ground
water that may be available for the well. Rainy seasons impact the
ground water positively; dry seasons impact it negatively.
- The head pressure in the well may resist
or reduce the flow of the aquifer into the well casing, if the well is
deep. The head pressure also affects the rate of water that the pump can
produce. The higher the head pressure, the easier it is for the pump to
lift the water.
- The depth of the well is a significant
factor, based solely on its storage capacity. A 50' deep well with a 5
GPM flow rate is not as good as a 200' well with a 5 GPM flow rate.
-
Occupancy impacts the well because the
higher the demand, the more difficult it is for the well to keep up.
When there are only two people and they both work, it is unlikely that
there may be a problem. When the house is not occupied, it may be even
more difficult to identify a problem.
