Catawba County Environmental Health has developed a guide providing an overview of the application, evaluation and permitting process.
You may now apply to install a well by downloading the application and bringing it to the Catawba County Permit Center in the Government Center at 100-A Southwest Blvd. in Newton, or mailing it to Catawba County Environmental Health at P.O. Box 389, Newton, NC 28658, together with the permit fee and all required additional information and documents. You must have zoning approval before your application will be processed.
When applying for well permits, read the Well Information Sheet carefully. Applications cannot be processed until all required information is received.
Well permits require that you include a plat or GIS printout of the property with locations of structures (or proposed structures), driveways, rights of way, existing wells or septic systems, streams, gullies, and other features drawn in.
For new construction or on vacant lots, applicants must prepare the property for evaluation by staking and stringing the property lines, the location of any proposed structure, the proposed location of the driveway, and any other structures such as pools, decks, gazebos, etc.
Once the application is returned and property is prepared for evaluation, applicants should call the Environmental Health Specialist for their area to arrange a visit. The proper Environmental Health Specialist can be identified by using this map.
Applicants must also post this sign at the property to be evaluated so the Environmental Health Specialist can locate it.
The Environmental Health Specialist will arrange to visit the property to perform the service for which the applicant has applied.
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 those water systems which have been subjected to repair must be thoroughly 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.
