Well Education

The purpose of this page is to educate our customers about groundwater and the process we take to provide water flowing out of your sink.

When we drill a well, our goal is to find an adequate source of groundwater. Many people think of groundwater as underground lakes or streams. Although that is the case in rare circumstances, most groundwater is simply water below the ground that fills in space between rocks or the cracks and crevices in rocks. The amount of water that a rock can hold depends on its porosity or the ratio of open space to the total volume of the rock. In sand and gravel, this ratio generally is 30 to 40 percent.
Groundwater can be found anywhere! It’s all a matter of how far we have to drill to find it. Groundwater comes from rain and snow percolating down through the soil. It drains down toward the zone of saturation, the area in which all openings are filled with water. The top of the saturation zone is called the water table, where the pressure is the same as that of the atmosphere. Although we start seeing the water below the water table, we drill until we hit a gravel aquifer or sufficiently cracked limestone. Aquifers consist of permeable rocks or granular materials that transmit water freely. These aquifers or cracked rocks (limestone) are able to replenish any water pumped out very easily. Depending on the formation of your well, it will only be able to replenish that water at a certain rate (Gallons Per Minute). The submersible pump must be matched accordingly not to pump more water than the well “makes”.

If your well is a gravel aquifer well, a well screen is placed at the bottom of the well to filter out the sand and gravel, while still allowing the water to pass by. If your well is a limestone well, a well screen is not needed and the bottom of the steel casing is left open inside the limestone.

Choosing a Contractor

When building or purchasing a home that needs a well, there are so many decisions to be made. Everything from roofing-flooring, cabinetry-well drilling must be considered. So how do you decide when there are so many details? At T.Huemann Well and Pump Inc., we believe the best consumer is an educated consumer. Here are some important items to consider when choosing a contractor:

Look for a contractor who takes the time to answer your questions.
A contractor should be servicing the customer from the first phone call. Questions often need to be asked AND answered! Remember you’re purchasing a product and have the right to know and understand what you’re getting for your money.

Look for a contractor who will talk to a woman about details.
Hard to believe, but yes it happens in this day and age too! At Huemann’s, we have found that most often it is the women who call to clarify details on a contract or question a component they don’t understand. Any contractor should be more than happy to service all of their customers.

Look for a contract that you are able to understand.
If the contract seems confusing, then it probably is–and it’s probably meant to be. Many confusing contracts have hidden costs. Have the contract clarified–what are you getting and what does it cost!! If it’s still confusing—BEWARE!

Look for a company that guarantees their work.
Any company who doesn’t stand behind their work must not be selling a good product. If you don’t see a guarantee on the contract, ask the contractor about it. Whatever verbal arrangements or promises are made, do be sure to get in writing also.

Do not base your decision solely on cost.
You’ve heard the old adage, “you get what you pay for…” A really cheap well/water system may be just that a really cheap well with hidden costs, no guarantee, and little to no servicing after the product has been purchased. It pays to shop around and compare pricing as well as service. A few extra dollars are worth the peace of mind in knowing good water will be flowing through your new home for years to come.

Constant Pressure / Variable Frequency Drive Systems

Are you frustrated by your low water system pressure?  A Constant Pressure system may be the answer.  Are you frustrated by your low water system pressure?  A Constant Pressure system may be the answer.

Constant pressure / variable speed systems are the latest and greatest in well water system technology.   Standard well pump systems operate on a mechanical pressure switch.  The standard switch turns the pump on 40psi and off at 60psi.  This means that the system pressure varies by 20psi throughout each cycle.  Constant pressure can be achieved electrically or mechanically.   Electric Constant pressure systems use a pressure transducer to monitor your water usage and transmit signals to your constant pressure controller to speed up or slow down your pump to maintain constant system pressure.    Mechanical constant pressure valve systems utilize a self-regulating valve that opens and closes to vary the flow and maintain constant system pressure. T.Huemann Well & Pump has been installing and servicing constant pressure systems since they were introduced to the well water industry.  We have experience with Pentek, Sta-Rite, Franklin, Berkely, ABB, Emerson, Yaskawa, Goulds, Cycle Stop, & Grundfos constant pressure systems


Constant Pressure System Benefits

  • Smooth, quiet operation
  • Eliminates water hammer
  • Smaller pressure tanks can be used and save precious space
  • Includes additional electronic protection features (Electric Constant Pressure)
  • Any existing system can be retrofitted for constant pressure control
