Diffusion of Innovation Explaining Support for Septic to Sewer System Conversion Programs Among Florida Residents: Lessons for Educators and Related Stakeholders

Dharmendra Kalauni, Laura A. Warner, Lisa Krimsky, Shelli Rampold, andSravani Pasula

Water quality impaired by excess nutrients has been linked to negative effects on human health, the environment, and the economy. Residential septic systems (i.e., onsite sewage treatment) contribute to these excess nutrients. Conversion from a septic system to a sewer system (hereafter referred to as S2S) is one way to mitigate pollution from excess nutrients. There are voluntary and mandatory S2S conversion programs throughout and beyond Florida. While there are multiple benefits of making such a change, S2S conversion is a complex and costly process. This document was developed to aid environmental management professionals, policymakers, and communication and education professionals (e.g., Extension agents) in understanding residents’ perceptions pertaining to S2S conversion. More details on the study presented in this document are available at: https://doi.org/10.1016/j.jenvman.2022.115651.
