Understanding public sentiment towards wastewater recycling may be more crucial than the technicalities of the process itself. A comprehensive study by the Institute for Public Policy Research and Analysis at the University of Oklahoma sheds light on Oklahomans’ views on reusing wastewater, revealing unexpected support for this sustainable practice.
PhD candidate Kaitlin Diodosio and her team sought to address common assumptions about the so-called “yuck factor”—the aversion to drinking reclaimed water. Contrary to traditional beliefs, their research indicates that financial and safety concerns, rather than the disgust factor, dominate public opinion.
“But what we find in this study is that not a lot of people are citing that as their main concern,” Diodosio explained. “Instead, people are more focused on, you know, how much does it cost? Is the program necessary and how are we validating this safety?”
The study, published in the Science of the Total Environment journal in July, underscores the importance of trust in leadership for the successful adoption of reuse programs. The findings suggest that acceptance of treated wastewater is closely tied to confidence in the entities managing these initiatives.
Highlighting the need for effective communication, Diodosio stated, “Sometimes these problems are handled at an expert level, right? They’re handled top down. But at the end of the day, in order for these policy solutions to be socially sustainable, you need public support.”
Oklahoma is already preparing for a future where water reuse becomes vital. Insufficient rainfall and prolonged droughts have troubled the state’s agricultural sectors, leading to the formation of a working group and the development of a 2023 action plan, following a 2012 law.
With climate projections indicating a hotter and drier future for the Southern Great Plains, water sources are increasingly under pressure. In Norman, a significant pilot project is testing the feasibility of indirect water reuse. This $3.4 million initiative aims to redirect treated wastewater back to Lake Thunderbird, potentially safeguarding the city’s water supply against future shortages.
The positive outcomes of the pilot, detailed in a 2022 study, have prompted discussions about long-term solutions. “Over-utilization of Lake Thunderbird, coupled with warnings of future droughts from climatologists, have sparked the need for creative solutions to ensure ample water supply for Norman’s future,” according to a 2022 city news release.
The research, supported by a National Science Foundation grant, engaged approximately 2,600 participants from diverse political backgrounds. It delved into their perspectives on climate change and water reuse as an adaptation strategy. Diodosio observed, “My perception of it is that as these environmental challenges become more salient in the public’s mind—meaning they’re closer in proximity, they’re feeling them more, maybe they’re more threatening to their everyday lives—people can put this political identity aside and consider how they react to the environmental problems a little bit differently.”
Unexpectedly, many respondents expressed a willingness to financially support wastewater reuse, with some willing to pay up to $30 a month over a decade. Diodosio concluded, “I think with the right communication and leadership with these problems, we have a real opportunity to implement these programs and secure water for our future.”
