From Well Drilling and Well Pumps to Water Filtration, Water Testing, and More!

New Hampshire’s Clean Water Center Professionals Keep Your Systems Safe, Healthy, and Maintained

Whether drilling a new well, testing water for arsenic, radon, bacteria, and other chemicals, or treating water for other strange tastes and smells, Capital Well Clean Water Center has been a trusted, expert source of well and water services for over 30 years. Building a new home and in need of a new well? Experiencing well pump failures or a no water emergency? Looking to schedule an annual well water test or installation of a water filtration system to ensure your water remains safe and clean for you and your family?

At Capital Well Clean Water Center, We Care About The Water Coming Into Your Home Or Business!

Water is one of the building blocks of life. We drink it, we shower and bathe with it, we cook with it. The existence of harmful chemicals can often go unnoticed, as many types of bacteria have no taste or smell, so the purity of your water is crucial to maintaining good health. In some cases, this may require repair or maintenance of a cracked well cap—or even cracked well casing—that allows surface contaminants to seep into the system. It may require the installation of a water treatment system such as an Ultra Violet Light, water softener, or filtration system.

We have a solution for all your home, business, farm, or commercial water problems. Do you have a water symptom? For all water systems - including city, town, and municipal water systems, call 603.774.6155 today to speak to our clean water professionals and learn how we can help deliver the safest and cleanest water to your family and employees.

Capital Well Clean Water Center 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 shoe or grout seal) prevents surface or subsurface contaminants from entering the water supply. The casing also provides a housing for a pumping mechanism and for the pipe that moves water from the pump to the surface. The quality of materials used in well construction is an important factor. Casing must meet certain specifications, since substandard pipe does not have sufficient strength to withstand driving without potential damage to the joints. Such damage may allow shallow or surface water to enter the well.

How much water will I need?

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

How often should I test my well water?

The National Ground Water Association (NGWA) recommends well owners test their water at least annually for bacteria, nitrates, and any contaminants of local concern. More frequent testing should be considered if:

  • Change in taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap, inundation by floodwaters, or a new contamination source
  • Well has a history of bacterial contamination
  • Septic system has recently malfunctioned
  • Family members or house guests have recurrent incidents of gastrointestinal illness
  • Infants or children are living in the home
  • Monitor the efficiency and performance of home water treatment equipment.

More FAQS...


Hydrofracking, sometimes called hydro-fracturing, is a well development process that increases the flow of water from a bed rock well.

Well Drilling

Artesian (bedrock) wells take their water from fractures in bedrock. These fractures are fed from the water table in the overlying soils.

Water Filtration

You'd think it would be obvious if there were things in your water that you'd rather not have in there. Things like radon, aresenic and other minerals are invisible.

Pump Systems

When you're on a well system and the water stops, it isn't always the well. It can also be the pump. Call us out to the house and we'll troubleshoot.

  • George Craggy

    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.
