WILTON MANORS · IRON STAINS

Orange & Rust Stains From Water in Wilton Manors

Orange or rust-colored stains on a Wilton Manors wall, driveway or pool deck usually come from a sprinkler system fed by a well, because groundwater can carry iron that oxidizes when it dries. City water, which Fort Lauderdale lime-softens and filters, is a less likely cause. Indoors, rust more often points to old galvanized pipe or a water heater. A test of each water source shows which one is responsible.

Irrigation wells and the river city

Wilton Manors is surrounded by the forks of the Middle River, and some properties water their landscaping from a well instead of city water. That well water is not treated. Iron in it turns orange as it dries on stucco, concrete and pavers. The city's two-day-a-week watering schedule applies to irrigation, and in Broward County all water wells, including irrigation wells, are permitted through the Department of Health.

Indoor rust

Many homes here were built decades ago. Galvanized steel pipe corrodes from the inside and can release rust, especially after water sits overnight. A water heater near the end of its life can do the same on the hot side. Wilton Manors' service line inventory sent letters to 2,945 properties whose private-side line material was unknown; if you got one, a plumber's inspection can answer both questions at once.

During the Prospect Lake transition

The city warned that Fort Lauderdale's move to its new plant, starting in September 2026, could temporarily change water color. Short-lived discoloration from the city is different from repeating orange stains outside. If indoor discoloration persists, call the Utilities Department at (954) 390-2190.

Cleaning existing stains

Once the source is fixed, existing stains still need cleaning. Products made for rust on concrete and stucco work better than bleach, which does not remove iron and can set some stains. Test any cleaner on a small area first, especially on pavers, colored stucco and pool finishes. On pool tile, stains from fill water can be handled by the pool professional as part of water chemistry. Without fixing the source, stains return within a few irrigation cycles, which is why the test comes first.

Treatment options

  • Irrigation well: an iron treatment system for the sprinkler line, chosen from the well's test, or rust-control approaches a sprinkler contractor recommends.
  • Drinking well: a well water system configured from the test.
  • Old pipes: plumbing repair, not filtration.

Common questions

Is city water staining my house orange?

Usually not. Sprinkler wells are the common cause of exterior orange stains.

Can stains be prevented?

Treating the irrigation water for iron, adjusting spray patterns, or switching irrigation to city water are common options.

Do I need a permit for an irrigation well?

In Broward County, the Department of Health permits water wells, including irrigation wells.

Why is my water brown after work on the street?

Main work or flushing can stir sediment. Run cold water and call (954) 390-2190 if it persists.

Is the test free?

Yes.
