Most Lewisville businesses and rental properties are on Winston-Salem/Forsyth County Utilities water and sewer through the Town's agreement with the City-County Utilities Commission, though rural-zoned edges may not be. Commercial plumbing here covers drains, restrooms, water heaters, backflow assemblies and service lines. Call the number on this page to be connected with a local plumber in Lewisville.

How Lewisville is set up
Lewisville incorporated in 1991 and centers on Shallowford Square and the old Lewisville Roller Mill, with US 421, NC 452 and Lewisville-Clemmons Road as its main routes. Building ages run mostly from the 1970s through the 1990s; the median home dates to 1987 and about 35% predate 1980.
The Town has an agreement with the City-County Utilities Commission, which provides water and sewer. Extensions are usually paid for by developers or the Commission through assessments, and requests from outside town limits are pointed toward voluntary annexation. The Town's Rural Overlay allows package treatment plants built to Commission standards, so a property in a rural-zoned area may drain to a small package plant or a private onsite wastewater system rather than a gravity sewer main.
Permits come from the joint Winston-Salem/Forsyth County Inspections Division, which lists Lewisville among the towns it serves. Backflow assemblies fall under WSFC's cross-connection program.
Comparing common commercial calls
| Situation | Usual fix | Lewisville detail |
|---|---|---|
| Backflow assembly due or failed | Test, rebuild or replace | WSFC-approved tester; report filed through BSI Online |
| Main drain backing up | Cable or jetting, camera if it repeats | Confirm whether the site is on a public main or a package plant |
| Water heater at end of life | Replacement sized to demand | Permit through the joint Inspections Division |
| New building or addition needing service | Tap and line extension | Commission and Town extension rules; annexation outside town |
Signs to act on
- Two or more drains slowing down together
- Gurgling from floor drains when a toilet is flushed
- A meter that moves with every fixture off
- A water heater relief valve dripping, or rust and moisture at the base of the tank
Seasonal and timing notes
WSFC's testing vendor mails a reminder about 30 days before a backflow test is due, which leaves time to fix a failure if the test is booked early rather than on the last day. Outdoor assemblies and irrigation piping should be drained or insulated before freezing weather. For planned work such as a water heater swap, booking a few days ahead makes off-hours scheduling easier to arrange than it is in the middle of a breakdown.
