This study assessed the effectiveness of improved storage containers on household drinking water quality in four low-income urban communities in Ibadan, Nigeria. 300 randomly selected respondents were interviewed, while 44 households were selected and randomly assigned to four improved containers treatment groups: Covered Buckets with Taps (CBT), Covered Buckets without Tap (CB), Covered Kegs with Taps (CKT) and Covered Kegs without Tap (CK). Water samples from springs, Regular Storage containers (RSC), and improved containers were analysed for Total Coliform (TC), Total viable bacterial (TVB) and E. coli for two weeks. About 96% reported using the same containers for cooking and drinking water, while only 23.3% used a form of water treatment. TC count for RSC and CB exceeded the recommended limit. Only 3 (6.8%) of the samples from RSC contained E. coli. Statistically significant difference was observed between the mean TC counts of samples from the improved containers. Percentage reduction in TC count from RSC, and improved containers (CB, CBT, CK and CKT) were 25.4%, 37.3%, 45.0%, 56.8% and 53.8% respectively. Bacillus, Staphylococcus, Klebsiella, Proteus and Pseudomonas were isolated from the water samples. CK produced the best result. Hygiene education on use of appropriate storage containers for drinking water is recommended at the household levels.
