Well Drilling & Pump Repair in Wake County, NC

Local Help in Wake County, NC

About 18 percent of Wake County residents depend on groundwater, according to a 2022 USGS study done with the county, and for most rural residents a private well is the main source of drinking water. The study drew on more than 7,500 Wake County wells: the median well is 265 feet deep with 68 feet of casing and yields 10 gallons per minute, but yields ran anywhere from 0.1 to 150 gpm.

Rock type explains much of that spread. USGS found the lowest yields in the Triassic sedimentary rock that fills the basin on the county's western side, east to the Jonesboro fault, and the highest in metavolcanic rock; yield tended to climb with depth to about 200 feet and then fall off. Water quality has its own map: the county expects about 1 in 5 wells in eastern Wake to have unsafe levels of uranium, radium, radon, or gross alpha or beta. Wake County owners and builders can request help with new wells, pump and pressure tank repair, and testing and treatment from independent local providers.

Service Area Notes

Requests are taken across Wake County, including unincorporated areas and the well country around Wake Forest, Rolesville, Knightdale, Wendell, Zebulon, Garner, Fuquay-Varina, Holly Springs, and Apex.
Mark a no-water or failed-pump problem as an emergency on the request form. Provider availability varies by area and day.
Wake County requires well contractors and pump installers to register with the county every year, and well contractors to post a $10,000 bond. North Carolina certifies well contractors by level. Ask any provider about both before work starts.

Common Jobs in Wake County

Submersible pump diagnosis and replacement when the house has no water
Pressure tank and pressure switch replacement on older rural systems
New wells for homesites beyond water lines, from county permit through the pump and wellhead inspection
Uranium, radon, and gross alpha testing and treatment on eastern Wake wells
Hydrofracturing low-yield wells, which North Carolina reserves for Level B certified contractors or higher
Raising buried-seal well casings above grade during repairs, as county rules require
Geothermal wells, drilled under county rules by IGSHPA-certified or equivalent contractors

What Drives Pricing Here

Depth. The median well in the USGS study is 265 feet deep with 68 feet of casing. On a pump job, a deeper setting means more pipe and wire to pull.
Rock and yield. USGS mapped the lowest yields in the western Triassic rocks and lower maximum yields in the southwest and northwest of the county. A new-well quote there should say what happens if the first hole comes in low.
Treatment after testing. Gross alpha results on a new well take three to four weeks, and the county puts the chance of needing treatment and a retest at about 1 in 7.
County fees. A new well permit is $800 and covers contamination-source review, inspections, sampling, and lab analysis. Repair and abandonment permits carry no fee.
Casing rules. Wake County's well regulations disallow black steel casing, and a repair on a buried-seal well has to bring the casing at least 12 inches above grade.

Permits & Local Rules

Wake County's Groundwater Protection and Wells Section, part of Onsite Water Protection, enforces county rules on well construction, repair, and abandonment (well inspections 919-856-7481; well water information 919-856-7482). A new well permit is $800 and good for five years. Repair and abandonment permits are free, and a construction authorization usually issues within one to two days.
New wells go through a site evaluation, a grout inspection requested by the certified well contractor, and a pump and wellhead inspection the pump installer must request within 72 hours of finishing. Bacteriological, inorganic, and nitrate/nitrite tests must pass before the certificate of occupancy; pesticide, VOC, and gross alpha tests are added in some cases.
The county's well regulations, amended in December 2024, go beyond state rules: wells at least 10 feet from property lines and 50 feet from other wells, and gross alpha testing for wells on Rolesville granite, Raleigh gneiss, Falls leucogneiss, and other listed rock units. State law (G.S. 87-97) doesn't require a repair permit to replace only a pump or tank.

Geology & Water Table Notes

In the USGS study of more than 7,500 Wake County wells, yields ranged from 0.1 to 150 gpm with a median of 10 gpm. Yield tended to increase with depth to about 200 feet and decrease below that.
Triassic sedimentary rocks in the western part of the county, bounded on the east by the Jonesboro fault, gave the lowest yields; metavolcanic rocks gave the highest. About 35 square miles in the southeast are Coastal Plain rather than Piedmont.
A UNC Superfund Research Program summary of Wake County well data found manganese above the standard in about 23% of 2,420 wells, iron in about 23% of 665, and uranium in about 10% of 411. Arsenic exceedances were rare, at 6 of 2,461 wells.
Northern Wake has a record of wells competing for water. The county's 2009 well-interference rules cite private wells affected in the Norwood Oaks and Bayleaf Trails subdivisions, and a USGS study of a northern Wake subdivision found 2008–09 water levels 100 to 200 feet down, against 15 to 50 feet from the 1980s to the late 1990s, with temporary failures in shallower wells.

Emergency Response Expectations

Mark a no-water problem in Wake County as an emergency on the request form, and mention livestock or medical water needs. Response time depends on provider availability. Check the breaker and the pressure gauge at the tank before the visit, and tell them what you see.

Wake County FAQs

How deep are wells in Wake County?

USGS's 2022 study of more than 7,500 Wake County wells found a median depth of 265 feet with 68 feet of casing. Yield generally rose with depth to about 200 feet and then dropped, so drilling much deeper isn't a sure fix for a weak well. Rock type matters: the western Triassic rocks gave the lowest yields.

Should I test my Wake County well for uranium?

If you're in eastern Wake, it's a good idea. The county expects about 1 in 5 wells there to have unsafe levels of uranium, radium, radon, or gross alpha or beta, and it has an address lookup map. Wake County's lab sells a Rads package for $140, which covers uranium, radon in water, gross alpha, and a radon-in-air kit, plus a $50 trip fee if staff collect the sample.

Do I need a permit to replace my well pump?

No. North Carolina law doesn't require a repair permit to replace only a pump or tank. Wake County does require pump installers to register with the county each year, so ask about that. A new well is different: the pump installer has to request a pump and wellhead inspection within 72 hours of finishing.

Our neighbors' wells are running low too. Is that a known problem here?

In parts of northern Wake, yes. County rules adopted in 2009 describe groundwater competition in the Falls Lake watershed affecting private wells in two subdivisions, and USGS documented falling water levels and temporary failures of shallower wells in a northern Wake subdivision in 2008–09. A provider can measure the water level in your well to show whether the pump is set deep enough.
