The Altamonte Springs–FDOT Integrated Reuse and Stormwater Treatment (A-FIRST) program is a breakthrough initiative that captures and treats stormwater runoff from I-4, processing an average of 1 million gallons daily for reuse. By transforming roadway runoff into a community asset, A-FIRST reduces nutrient pollution in the Little Wekiva River, supports aquifer recharge and removes the need for additional retention ponds, saving the state $15 million in construction costs.
For the first time in Florida’s history, the Florida Department of Transportation (FDOT) opted not to build a traditional retention pond. Instead, the City of Altamonte Springs now captures stormwater runoff from I-4, treats it and repurposes it for landscape irrigation. In a state where water supply is an urgent concern, this approach provides a sustainable alternative to withdrawing from the aquifer.
Under conventional designs, stormwater from I-4 would enter roadside ponds, allowing pollutants to settle and potentially seep into groundwater. A-FIRST replaces that model with a cleaner, more efficient process. Runoff is intercepted, treated and directed into the City’s reclaimed water system, where it supports irrigation. Any excess supply is shared with the City of Apopka, helping ease regional water demands.
This initiative not only establishes a reliable alternative water supply but also improves water quality in natural springs and reduces nutrient loads entering the Little Wekiva River. The project is primarily funded by the State of Florida, leveraging cost savings from eliminating the need for expensive retention pond construction.
A-FIRST is a collaborative achievement supported by FDOT, the Florida Department of Environmental Protection, St. Johns River Water Management District and the City of Apopka. Together, these partners show how coordinated action can tackle complex environmental challenges.
A-FIRST is a clear example of Altamonte Springs’ leadership in delivering sustainable, cost-effective infrastructure. It reflects a forward-thinking, business-minded approach to water management and sets a model for cities seeking practical innovation with long-term impact.
