Key Largo Wastewater Treatment District needs your cooperation to protect the wastewater system particularly now due to the current COVID-19 outbreak. People are cleaning and disinfecting more frequently with bleach wipes and potentially substituting other items for toilet paper, such as baby wipes and paper towels.

KLWTD is asking customers to throw these items in the trash, not flush them down the toilet. These items do not break down in the sewer system and can cause significant clogs that could lead to equipment failures and treatment plant issues.

It is important to only dispose of toilet paper and human waste in the toilet. Otherwise, it can cause costly clogs or back-ups in your sewer system.

Here is a list of items that should never be flushed down the toilet:

Disposable wipes (even if marked "flushable")
Wet Wipes
Paper Towels
Facial Tissues
Face-Cleaning Wipes
Grease / Oils
Feminine Hygiene Products
Cotton Swabs / Cotton Balls
Diapers
Dental Floss
Medicines / Vitamins
Cigarettes / Cigar Butts

MONROE COUNTY CONTINUES TO WATCH HURRICANE DORIAN, POTENTIAL FLORIDA KEYS IMPACTS STILL ‘HIGHLY UNCERTAIN’

Monroe County Emergency Management continues to prepare for the possibility of potentially damaging winds, heavy rainfall, coastal flooding, and fast-moving squalls with Hurricane Dorian’s projected path.

As of the current 2 p.m. Thursday weather briefing by the National Weather Service Key West, specific weather impacts remain uncertain for the Florida Keys, but damaging tropical storm force winds and squalls are possible and could be expected throughout the Florida Keys on Sunday and Monday, especially in the Upper Keys areas and Ocean Reef.

The Upper Keys, Tavernier, Rock Harbor, and Key Largo, could also experience coastal and street flooding on the bayside that can be comparable to the highest king tides that have been historically experienced in that area.

“Watches could be issued for portions of the Florida Keys sometime Friday,” said Jon Rizzo, National Weather Service Key West. “But remember that impacts can extend far outside the cone.”

Monroe County Emergency Management’s critical staff has checked in and is prepared to activate if needed. The County is waiting until after tomorrow morning’s briefing to decide if the Emergency Operations Center will need to be set up.

“We are still three days out from a major hurricane heading toward the east coast of Florida and the cone of error is still very large,” said Marty Senterfitt, Director of Monroe County Emergency Management. “The Upper Keys are still in that cone.”

County Administrator Roman Gastesi said now is not the time to let any guard down. “Timing of Dorian’s turn is critical to the impacts the Florida Keys will experience,” he said. “Dust of your hurricane plans and be ready to implement them on a moment’s notice”

The County is taking extra precautions like gassing up vehicles and wants residents to continue to monitor the storm. Now is the time to fuel up vehicles, stock up on supplies, and keep cash on hand. Hurricane preparation information can be found at www.monroecountyem.com.

The Florida Department of Environmental Protection (DEP) and the Key Largo Wastewater Treatment District (KLWTD) are working together to respond to water quality concerns from Key Largo residents. Recently, DEP and the KLWTD received an influx of calls regarding a strong “sewage odor” in some residential canals, mainly on the oceanside of Key Largo and Tavernier. Working in collaboration with DEP, the KLWTD staff collected and tested water samples in canals, which did not show any evidence of sewage contamination. Rather, DEP Investigators observed large amounts of dead sargassum seaweed, which when decays inside the canal, may cause a sulfur gas odor and low dissolved oxygen levels. DEP is partnering with the Key Largo Wastewater Treatment District to address these concerns.

If you encounter fish that are either dead or in poor physical condition, please contact FWC’s toll-free Fish Kill Hotline at 1-800-636-0511.

A wastewater transmission line at mile marker 92.5 broke Tuesday, March, 5th at approximately 10:30 AM then again at 10 PM. Repairs have been made to the force main line that transmits wastewater effluent from the Islamorada sewer system to the Key Largo Wastewater Treatment Plant. KLWTD system was unaffected by the problem. Long term solutions are being researched to prevent future breaks.

Northbound traffic on US 1 is reduced to one lane until the repairs are complete. Repairs should be completed, and the lane reopened by 5 PM. There are traffic delays northbound on US 1 that will continue throughout the day.

The lane closure begins near the Dairy Queen restaurant and ends at Burton Drive. Access to all businesses and residential streets are open.
