The South Seminole and North Orange County Wastewater Transmission Authority (SSNOCWA) was created by an Act of Florida Legislature in 1978 as a separate local agency of the government with powers designed to meet the particular needs of the area in relationship to transmission of wastewater to a regional sewage treatment plant (Iron Bridge Treatment Facility).
Design work for the Authority began in the spring of 1979. Construction grants were obtained from the Environmental Protection Agency (EPA), and Bond Anticipation Notes were issued during 1981 in the amount of $7,000,000. Construction on the system began in February 1982. Initial flows into the system were begun in February 1983 and the total system completed in the fall of 1983. The Bond Anticipation Notes issued in December 1981 were replaced by Sewer Revenue Bonds in December 1983 and replaced at lower interest rates with bond issues in 1986 and 1993. EPA grants in the amount of $8,876,992 had been received by September 30, 1984. Upon the pay-off of the 1993 Sewer Revenue Bonds, new bonds were issued in the amount of $8,515,000 to fund Phase I of the Master Plan-Capital Improvement Projects (CIP).
