Service Area
The District’s boundaries include the territory consisting of Key Largo, including all lands east of Tavernier Creek, including Tavernier, Key Largo, and Cross Key, with the exception of Ocean Reef, all located in Monroe County.
System
In most of the island of Key Largo a vacuum collection system is the most cost effective method for wastewater collection. In some remote areas a gravity collection system that pumps directly into the US1 force main is the most economical alternative. A vacuum sewer system uses the differential pressure between atmospheric pressure and a partial vacuum maintained in the piping network and vacuum station collection vessel. This differential pressure allows a central vacuum station to collect the wastewater of several thousand individual homes. Vacuum sewers take advantage of available natural slope in the terrain and are most economical in flat sandy soils with high ground water. Vacuum systems are completely contained and will continue to function normally during a power outage with power from a standby generator located at the vacuum stations.
