Understanding urban-suburban adoption and maintenance of rain barrels

Stormwater best management practices (BMPs) can help local communities alleviate water runoff and reduce pollution in a cost-effective way. However, few researchers have examined the adoption of stormwater BMPs in urban-suburban communities. The purpose of this study was to explore the factors influencing adoption and maintenance of rain barrels, a commonly promoted urban-suburban BMP, in two watersheds in Indiana. The resulting analysis of quantitative survey data, qualitative interview data, and practice assessment field data indicated that: (1) People with more positive attitudes towards the environment and higher level of knowledge about practices are more likely to adopt practices; (2) Gardeners with the intention of reducing water use in their yard were the most prevalent adopters and should be targeted for future stormwater conservation practices; (3) Between 25% and 35% of practices were discontinued within five years of their adoption; and (4) Informational signage stating adopters' commitment to practices and support for the environment is a potential strategy for fostering practice maintenance over time.
