The role of personal experience in frequency of rainwater tank maintenance and policy implications

Abstract

Domestic rainwater tanks have a long history in Australia, although more recently they have been common only in remote and rural areas. However, in some urban areas, recent drought conditions have led to the promotion of rainwater tanks to supplement domestic water supplies. Evidence suggests that water tank maintenance may be insufficient in many cases, leading to problems with water quality and the potential spread of vector-borne disease. Drawing on research into the impact of personal experience (i.e. procedural knowledge) relating to pro-environmental behaviour, a survey of urban residents with mandated rainwater tanks (N = 746) was conducted. The study assessed whether past personal history of living with a tank influenced the frequency of tank maintenance behaviours. Analyses indicated that both childhood and prior adult experience with rainwater tanks were important in predicting adequate tank maintenance behaviour, particularly among males. The results also showed that attitudinal perceptions of water culture did not influence maintenance behaviour, whereas direct past experiences did, suggesting an important role for procedural knowledge. These results are discussed with reference to the promotion of tank maintenance and other pro-environmental behaviours through the development of future environmental policies designed to foster the development of pro-environmental skills to empower citizens.
