Perception and acceptability of the public towards the use of harvested rainwater in water scarce regions

Abstract

This study discusses the critical importance of sustainable access to clean water, particularly in regions facing severe water shortages. The study investigates the public perception of harvested rainwater as a solution to water scarcity in South Africa's semi arid regions. Conducted with 110 respondents, it explores demographics, rainwater harvesting practices, storage methods, and factors affecting satisfaction. Most households (39.6%) had four to six members, with a balanced gender distribution. Despite widespread unemployment (53.2%), 33.6% were graduates. Rainwater was harvested primarily during rainfall (64.9%), with 94.5% of the respondents collected from their own roofs. Storage methods included JoJo tanks (41.8%) and small buckets (54.5%). Concerningly, 95.5% did not test water quality, yet 64.5% found it acceptable. Regression analysis showed water quality significantly influenced satisfaction (b = 0.623, p < 0.005). The high prevalence of rainwater harvesting underscores its potential to address water shortages sustainably.
