Infrastructure reference · Five-county utilities
Across Mecklenburg, Union, Cabarrus, Gaston, and Iredell counties, water and wastewater availability is often the single biggest divider between rural acreage value and high-density development value. Here is how utility systems govern land across all five counties — and why a pipe in the road is only the start of the conversation.
Five-county utility overview
Every county in our footprint organizes water and wastewater differently — from a consolidated countywide utility in Mecklenburg to multi-basin county and municipal authorities in Union, Cabarrus, Gaston, and Iredell.
| County | Primary utility providers | Verified infrastructure & basin dynamics | Screening boundary |
|---|---|---|---|
| Mecklenburg County → | Charlotte Water | Region-wide water and wastewater system serving Charlotte and the six Mecklenburg towns. Even inside Charlotte Water's service area, infill and transit-corridor redevelopments must verify local main sizing, fire-flow pressure, and downstream sanitary sewer capacity. | Main proximity checked in GIS; hydraulic capacity requires Charlotte Water engineering review. |
| Union County → | Union County Water · City of Monroe Water Resources | Union County Water operates across 5 wastewater reclamation basins (Twelve Mile Creek, Crooked Creek, Grassy Branch, Tallwood, Olde Sycamore) plus part of the Marshville-Monroe system. The Twelve Mile Creek plant has a reported $48.5M upgrade targeted for 9 MGD, new water/sewer review fees took effect Oct 1, 2026, and FY2026–27 rates help fund treatment and line expansion. | Basin boundaries checked; allocation availability requires Union County Water / Monroe review. |
| Cabarrus County → | WSACC (Rocky River WWTP) · Concord · Kannapolis · Harrisburg · Mount Pleasant | The Water and Sewer Authority of Cabarrus County (WSACC) manages regional wastewater interception and treatment, while individual municipalities manage retail water/sewer connections and often tie extensions to municipal annexation and rezoning. | Jurisdiction & WSACC interceptor corridors checked; municipal allocation requires town verification. |
| Gaston County → | Two Rivers Utilities (Gastonia / Cramerton) · Belmont · Mount Holly · Bessemer City · Cherryville · Dallas | Two Rivers Utilities is the primary regional provider around Gastonia and Cramerton, alongside individual municipal systems. Gaston County's Economic Development Commission explicitly targets water and sewer line extensions to unlock additional industrial sites. | Provider service area checked; main extension and annexation requirements require municipal confirmation. |
| Iredell County → | City of Statesville · Town of Mooresville · Town of Troutman · Iredell Water Corporation | Water and wastewater service splits between northern/rural agricultural areas (often on well/septic or water-only lines via Iredell Water Corp.) and southern/interstate growth corridors served by Statesville, Mooresville, and Troutman. | Service territory checked; municipal utility annexation and capacity require town engineering review. |
Beyond “is there a pipe at the street?”
When we prepare a preliminary land review, we explicitly label what public utility maps show (Source checked) versus what requires formal utility engineering verification (Confirmation needed).
A parcel can sit inside a utility provider's future service area while the nearest active gravity sewer line is still half a mile away across a ridge or rail line.
Wastewater flows downhill by gravity unless pumped. If a tract lies in a lower drainage basin than the nearest sewer trunk, a builder may have to construct a lift station and force main — or assemble an easement through a neighbor's parcel.
Even when a pipe runs directly along a parcel's frontage, the receiving wastewater treatment plant or sub-basin may have limited remaining gallons-per-day (GPD) allocation.
Connecting an unincorporated county parcel to town water and sewer often triggers a mandatory petition for voluntary annexation, shifting the property from county zoning to town zoning.

Landowner guide →Buyer & developer brief →No. A mapped water main or gravity sewer line near your frontage only confirms physical proximity. Whether a subdivision, townhome, or industrial project can connect depends on hydraulic main sizing, downstream pump station capacity, treatment plant allocation in that basin, and municipal annexation rules.
Rapid residential growth across Union and Cabarrus counties has made wastewater treatment allocation one of the primary pacing items for new subdivisions. In Union County, for example, service spans five wastewater reclamation basins — including the Twelve Mile Creek facility targeted for a $48.5 million upgrade to 9 MGD — and new water/sewer review fees took effect October 1, 2026.
Frequently, yes. In counties such as Cabarrus, Gaston, and Iredell, municipal utility providers (or regional authorities allocating capacity through member towns) commonly tie water and sewer extension outside city limits to voluntary annexation and rezoning under the town's development ordinance.
