Lewisville's water and sewer come from the City-County Utilities Commission under an agreement with the Town, but the Town's Rural Overlay means not every area is on a public line. Where a home still has its own well, the pump, switch and pressure tank are the owner's to maintain. Call the number on this page to be connected with a local plumber in Lewisville.

Public lines and the Rural Overlay
Under its agreement with the Commission, water extensions in Lewisville are normally paid for by developers or the utility, with assessments on the properties served. Requests to extend lines outside town limits are steered toward voluntary annexation. Town policy also talks about existing private systems in rural-zoned areas, but nothing we found counts how many Lewisville homes use wells.
Housing here is mostly from the 1970s through the 1990s (median year built 1987), so a well home on the town's edge may have a pump, tank or switch that has been in service a long time.
The Rural Overlay also allows package treatment plants built to Commission standards, which is a reminder that utility service in Lewisville is decided parcel by parcel. Before you plan a repair, confirm whether your home has a meter or a wellhead. If both exist on the same lot, tell the plumber, because an old well left connected to house plumbing on public water is a cross-connection concern the utility will care about.
Comparing your options
| What failed | Repair option | Replacement makes sense when |
|---|---|---|
| Pressure switch | New switch, adjusted to the tank | Almost always; switches aren't rebuilt |
| Pressure tank | Restore the air charge | The bladder has failed or the tank leaks |
| Control box or capacitor | Replace the component | Failures keep coming back |
| Submersible pump | Rarely repaired in place | The motor is burned out or the pump is worn |
| Private line to the house | Patch the leak | The pipe is brittle and leaking in several places |
Signs to watch for
- No water anywhere in the house
- A pump that runs with every fixture closed
- Pressure that swings during a shower
- Rapid clicking from the switch
- Air or grit coming through the taps
Seasonal notes
Summer is when a tired pump gives out, since lawns, gardens and guests push it hardest. Thunderstorms bring surges that can kill a control box or capacitor. Winter brings freezing risk to a wellhead line or pump house that isn't insulated or heated. If you're on public water instead, sudden pressure changes are more often a leak on your own line or utility work nearby. Permits in Lewisville go through the joint Winston-Salem/Forsyth County Inspections Division.
