Supplying Your Home with the Right Amount of Well Water

At EDS Pumps & Water Treatment Ltd., we understand how important well services are for ensuring that your well is supplying your home with the right amount of well water. That is why we offer a wide range of water services for wells, including well cleaning, well disinfection, well closure, and well chemicals.

Where Does Well Water Come From?

Groundwater comes from an aquifer. An aquifer can cover many square miles and is composed of spaces filled with water in various layers of material beneath the ground. In one area, there may be sand or gravel deposits. In others, the shale may contain many fractures. Still others have dense rock that may have relatively few fractures. These cracks and voids fill with the water that soaks down through the ground and form a water-bearing stratum called an aquifer.

Once a well fills to its static level, the level at which water in the well is the same as that in the ground around it, no more water will come in. If no water is removed from the well, it will cease producing. If water is withdrawn from the well, more will come in. Most wells spend a majority of their lives in a non-productive state.

How Do Wells Run Out of Water?

Two things limit the amount of water that a well can produce—time and well yield.

The water level in a well will vary depending on the rate and duration of pumping cycles. The well yield increases toward its maximum as the water level inside the well declines. The lower the level inside compared to that outside, the larger the pressure difference and the faster water will move in. The closer the level inside compared to that outside, the slower the well fill rate will be.

Low-yield wells pumped for long periods experience significant variations in water level. Pump performance in low-yield well installations vary with water level changes. Every pump has a finite amount of energy that it can spend to lift water and provide pressure. The more energy it must spend lifting water, the less is available with which to provide pressure. When supplying a building directly from a low-yield well, system performance often becomes poorer the longer the pump runs.

Well Services from EDS Pumps & Water Treatment Ltd.

It’s not difficult to supply a home requiring 20 gpm (gallons per minute) peak demand using a well with a 1-gpm yield or less, if you separate collection and delivery.  Collection must be based on well yield and arranged to keep the well producing while the delivery pump must be sized to supply the peak demand flow rate from atmospheric storage. If a well yields enough water in 24 hours to meet a family’s daily needs and the correct equipment is installed, there’s no reason that the plumbing performance for that house shouldn’t be as good as, or better than, any home on a public water supply.
