Wastewater management in the Florida Keys has long been shaped by the region’s geography: a narrow island chain with a high water table, porous limestone and globally significant marine ecosystems. When studies in the 1990s linked coral reef decline to failing septic systems, the need for centralised wastewater treatment became unavoidable. A 1999 state mandate accelerated this shift, and vacuum sewer systems were adopted in many areas because they could be installed close to the surface and above groundwater, reducing excavation costs and long term risk. In Key Largo, residents chose to take control of their wastewater future by forming the Key Largo Wastewater Treatment District (KLWTD) in 2002. Construction of a centralised system began in 2005, and by 2010 the new treatment plant served around 10,500 people. Later upgrades increased capacity and strengthened the system against storm impacts. Today, the network includes roughly 89 miles of vacuum main, seven pump stations and nearly 2,900 valve pits. Operational pressures and...
