Frequently Asked Questions - Our FAQs


What exactly is a drilled well?

A drilled well consists of a hole bored into the ground, with the upper part being lined with casing. The casing prevents the collapse of the borehole walls and with a drive shore or grout seal to prevent surface or subsurface contaminates for entering the water supply.

How much water will I need?

It depends on what the water demands are for your household. For example, do you have irrigation, hot tubs, multiple bathrooms, and other utilities that demand water? All these items make a difference from home to home. When you meet with our water well professionals they'll be able to discuss your water usage and needs.

What determines how deep will my well need to be?

Well drilling is very unpredictable; there is no exact science of locating the water before you start drilling. However if you consult with your immediate neighbors that have wells it will give you a general idea of the average depth in your area. Also a state or local regulating agency may have record on file of wells in your neighborhood.

We're planning on building a new home. When is the best time to drill a well during construction?

After gravel has been laid on the driveway and before the foundation is poured is the ideal time to drill the well at your new home. A drill rig set up takes up a lot of room on a site and is very noisy, so its typically ideal to drill the well early on in the construction process, although it isn't absolutely necessary.

What is the best location for my well?

The location of your well will be decided by a) state and local codes, including septic, property lines, wetland and other various setbacks; b) Proximity of utilities; c) accessibility for drilling equipment.

How much of a mess will the drilling rig make of my yard?

If it is a new construction and the landscaping has not been completed then cleanup is simple. When drilling in established areas some minor landscaping may be needed after the well is completed. However, we have years of experience and always try to leave you with as little repairs as necessary to your landscaping.

Is there a way to know how much water my well will produce?

Unfortunately, there is no way to predict in advance how much water your well will produce. On average for every foot of drilling you will have 1.5 gallons of water delivered. This, combined with the recovery of the well (gpm) will dictate when you have enough water for your specific water needs.

Will my well need service?

The well itself will probably not need servicing. The expected/average life of a well's pumping equipment is 10-20 years.


How does a geothermal system work?

Throughout the year, outdoor temperatures fluctuate with the changing seasons. However, underground temperatures do not. In fact, about four to six feet below the earth's surface, temperatures remain relatively constant year-round. A geothermal system, which consists of an indoor unit and a buried earth loop, capitalizes on these constant temperatures.

In the winter, fluid circulating through the system's earth loop absorbs stored heat and carries it indoors. The indoor unit compresses the heat to a higher temperature and distributes it throughout the building. In the summer, the system reverses, pulling heat from the building, carrying through the earth loop and depositing it in the cooler earth.

What makes geothermal system different from conventional systems?

A geothermal system uses the energy from the sun, which is stored in the earth, to heat and cool homes and buildings. Typically, electric power is used only to operate the unit's fan, compressor and pump. So, unlike conventional systems, geothermal systems do not burn fossil fuel to generate heat--they simply transfer heat to and from the earth.

What does geothermal mean for the environment?

Because geothermal systems work with nature, not against it, they minimize the threats of acid rain, air pollution and the greenhouse effects.

Do geothermal systems require much maintenance?

No. In fact, geothermal systems are practically maintenance free. When installed properly, the buried loop will last for generations. And the other half of the operation — the unit's fan, compressor and pump — is housed indoors, protected from the harsh weather conditions. Usually, periodic checks and filter changes are the only required maintenance.

    Jonathan, I wanted to drop a couple of lines to tell you how satisfied and happy that I chose Capital Well Co. for my water needs. From your lead man Steve to your drill people, your plumbing guy and your guy on the back hoe. Everyone that cast a shadow on my door threshold were polite, professional and willing to take the time to explain and answer my questions; which were many . Jon, it was my pleasure to meet you today and pleased that you came by for a follow up visit and explain how the heater works. SO...if I get a chance to tell everyone that needs a new well, I definitely will. It is apparent there is no "I" in your team . Thank you everyone.
  • Richard Meaney

    Mr. Swain, Thank you so much for the service Capital Well provided at my home today. I left a message with you at the behest of Ed Monty. I received a prompt phone call from Greg to arrange for a service call and to discuss what might need to be done. Promptly at (actually a few minutes before) the scheduled time, Bobby showed up to perform the service. Bobby was excellent at explaining the service, why some things were needed and how the well and pump worked, and answered all of my questions to my satisfaction. All in all, this was a very positive experience for us. Thanks to you and the people at Capital Well for prompt, courteous, and efficient service.
