The Catawba County Private Water Supply Wells Program supervises the siting, installation and protection of private water supplies, and monitors the performance of well contractors in Catawba County. Maintaining clean drinking water for families and businesses is important to the overall health of individuals and the community as a whole.

Drilled wells are typically created with an air rotary drill, a good method for drilling into medium-packed to hard-packed bedrock to access ground water. Drilled wells are cased in 6 inch polyvinyl chloride (PVC) piping or steel casing from the surface through the first five feet of hard-packed rock to guard against mud and other contaminants from entering the water. The casing is also grouted to a point 20 feet below the surface. The amount of water obtained from drilled wells will depend on the number and size of the fractures made by the bore hole in the bedrock, and may range from 1/2 a gallon per minute to 100 gallons per minute. This type of well is usually not affected by short-term drought conditions because of the natural geology and the ways in which water reacts with land in Piedmont North Carolina. Drilled wells may sometimes have excessive mineral content, particularly with iron, iron sulfide, manganese, magnesium and calcium, which can only be removed by filtration.

Bored wells are constructed with an auger that digs until it reaches the water table or encounters a material such as rock, which restricts or stops the auger. Bored wells are shallow and draw water from sections of the earth above the bedrock. The amount of water obtained will depend directly on the level of water in the water table and how quickly the well is able to refill. Bored wells are cased by 24-inch diameter concrete pipe, which is set when it reaches the water table. Pea gravel is placed in the bottom of well and poured on the outside of the casing to act as a filter to keep out sediment and support the side walls of the bored hole. Bored wells are also grouted on the outside of the casing 20 feet below the surface. Bored wells are the modern version of the older style of dug wells. They are usually more susceptible to changes in the water table from periods of drought or excessive rain. They typically have fewer problems in the Piedmont with excessive minerals in the water such as iron, manganese and calcium, but are more affected by surface water and possible contaminants.

New water systems and water systems that have been under repair must be disinfected before use. Handling and storage of materials, supplies, and equipment during construction make contamination almost certain. Chlorine and chlorine compounds are effective disinfecting agents when properly used. See our guide for Well Disinfection Procedures for more information.

Water samples can be obtained from Catawba County Environmental Health by visiting the Government Center at 25 Government Drive in Newton to submit an application and pay applicable fees.

The Environmental Health Specialist for your area can be found here.

Bacteriological sample results take 4-5 days, chemical sample results take 3-4 weeks and all other sample results take 1-2 months. If a bacteriological sample is for a loan closing, allow 3-4 weeks for collection, transport, and analysis of sample, disinfection of well if sample is positive, and resample.

Applicants should keep a copy of the completed application until the process is complete.

  • Well pumps run off of electricity. Do not use a well that has been submerged in water or exposed to flooding conditions. Have all electrical components inspected by a licensed electrician before connecting to a power source.
  • Chlorinate/ disinfect the well.
  • Test water quality before using the water for any purpose.
