How do I choose a well company?
As with any contractor, homeowners should ask well drillers for references, professional
certifications, licenses and proof of insurance and should confirm that the company
provides maintenance and service. In addition, a reputable company will be
knowledgeable about local and state laws, the area’s geology and will provide the
homeowner a detailed contract.
When a well is drilled, who applies for permits, sets appointments for inspections?
The homeowner or their building contractor applies for the necessary permits. A well
driller can guide you on which agencies to contact, what fees must be paid and sets
required on-site appointments with inspectors. Click here for general well drilling
information issued by the Catawba County Environmental Health Department.
Can a driller tell me how deep my well will be and how much water it will yield?
No competent driller can tell a homeowner that. However, after determining your
water usage, a driller can give estimates based on their experience with other wells in
What is a drilled well?
Drilled wells are usually made with an air rotary drill which allows drilling into
medium-packed to hard-packed bedrock in order to access natural aquifer or water
table. The amount of water yielded from drilled wells is directly affected by the number
and size of the fractures made by the bore hole in the bedrock. This type of well usually
is not affected by short-term drought conditions due to the natural geology and the
ways in which water reacts with land in this area of North Carolina. They can yield
water with excessive amounts of minerals such as iron, iron sulfide, manganese,
magnesium, calcium, etc. which only can be removed by filtration.
What is a bored well?
Bored wells are constructed with an auger that digs until it reaches the natural aquifer
or encounters a material such as rock, which restricts or stops the auger. Compared to
drilled wells, bored wells are shallower and draw water from sections of the earth above
the bedrock. The amount of water yielded by bored wells is directly affected by the
water table’s level and how quickly the well is able to refill. These wells usually are
more susceptible to changes in water table level during periods of drought or excessive
rain. Bored wells located in this part of North Carolina typically have fewer problems
with excessive minerals in the water such as iron, manganese, calcium, etc. than drilled
wells but are more susceptible to surface water and possible contaminates.
What is a well history and why is it important?
If you are buying property with an existing well, the previous property owner should
have kept a history of the well that includes information such as the name of the drilling
company, the year of installation, construction specifics, well depth, water pressure,
testing history, information on filtering systems and their maintenance. This is highly
valuable information for a well company when performing repairs, maintenance and
Do I have to disinfect my well?
Yes. This can be done by the homeowner, especially after repairs where contamination
is inevitable. Click here for disinfecting guidelines issued by the Catawba County
