SOUTH DISTRICT WASTEWATER
TREATMENT PLANT EXPANSION AND
NORTH AND CENTRAL DISTRICT
INJECTION WELLS PROJECT
BORROWER: Miami-Dade County
LOCATION: Miami, FL
WIFIA LOAN AMOUNT: $235.2 million
TOTAL WIFIA PROJECT COSTS: $480 million
POPULATION SERVED BY SYSTEM: 2.3 million people
NUMBER OF JOBS CREATED: 173 jobs
PROJECT DESCRIPTION
Miami-Dade Water and Sewer District's South District Wastewater Treatment Plant Expansion
will increase the permitted treatment capacity from 112.5 million gallons per day to 131 million
gallons per day annual average daily flow and increase the peak hourly flow capacity of the
facility. The department will also construct new municipal injection wells at the North and
Central District Wastewater Treatment Plants, which will help fulfill requirements of the state
of Florida's Ocean Outfall Legislation. The wastewater conveyance system to the three
wastewater plants is interconnected, so flow can be directed between wastewater treatment
plants to allow for operational flexibility. By increasing capacity at the South District
Wastewater Treatment Plant, service for the whole regional system improves.
PROJECT BENEFITS
	Enables Miami-Dade County to complete its Ocean Outfall Legislation Projects,
eliminating the regular use of ocean outfalls and protecting the near-shore aquatic
ecosystem off the coast of Florida.
	Diverts ocean outfall discharges which will reduce nutrient pollution and improve water
quality on the Florida coast and the surrounding coastal ecosystem.
	Saves Miami-Dade County an estimated $80.2 million from financing with a WIFIA loan
compared to a bond issuance.
