Brown or Cloudy Water After Heavy Rain? What Polk County Homeowners Need to Know
Brown Water After a Storm Is a Warning Sign
A big Central Florida storm rolls through, and the next morning your tap runs brown, yellow, or cloudy. It's one of the most common calls we get across Polk County. The good news: the cause is usually easy to pin down. The important part is knowing which cause you're dealing with, because the fix for well water is different from the fix for city water.
If You're on a Private Well
Most homes around Mulberry, Bartow, Fort Meade, and rural Lakeland draw from private wells. Heavy rain changes what's coming out of the ground:
Sediment and sand. A sudden rise in the water table stirs up fine sediment that settles back into your pressure tank and lines.
Iron. Florida groundwater carries dissolved iron. When rainwater adds oxygen to the system, that iron oxidizes and turns your water orange or rusty brown.
Tannins. Water that filters through decaying leaves and organic soil picks up a tea-colored tint, especially in shallow wells.
Surface water intrusion. A cracked well cap, damaged casing, or flooding around the wellhead lets surface water in directly.
If your wellhead was underwater at any point, stop drinking the water. Use bottled water, disinfect the well, and have it tested for bacteria before you drink from it again. The Florida Department of Health publishes well disinfection guidance for exactly this situation.
If You're on City Water
City customers in Lakeland, Winter Haven, and the rest of the county see discoloration too. The usual causes:
Main breaks and pressure changes. Storms and power outages cause pressure swings that knock loose sediment and mineral scale inside the city's mains.
Hydrant flushing. Utilities flush lines after storms, which temporarily sends rusty water to nearby homes.
Your own plumbing. Older galvanized pipes release rust when water flow changes suddenly.
City-side discoloration normally clears within a few hours. If it keeps coming back, the problem is in your home, not the street.
What to Do Right Now
Check hot versus cold. If only the hot water is brown, the problem is sediment in your water heater. Flush the tank.
Run the cold tap nearest your meter or well for 5 to 10 minutes until it clears.
Hold off on laundry. Iron sets permanent stains in white clothes. Wait until the water runs clear.
Check for boil water notices from your utility if you're on city water.
Get it tested if the discoloration lasts more than a day or returns after every rain.
How to Stop It for Good
Brown water that shows up every rainy season is telling you your water needs treatment. For well owners, the right setup depends on what's actually in the water:
Sediment filtration catches sand and grit before it reaches your fixtures and appliances.
Iron and sulfur filtration removes the iron that turns water orange and the hydrogen sulfide behind that rotten-egg smell.
A salt-based water softener removes hardness minerals and handles low levels of dissolved iron, protecting your water heater and plumbing.
Reverse osmosis at the kitchen sink gives your family clean, great-tasting drinking water every day.
For city customers, a whole-home filtration system traps sediment and removes the chlorine taste and smell, so a main break down the street doesn't show up in your shower.
