“…Stainless steel vessel retained 23.5 per cent of initial coliforms on tenth day of storage. Mehta et al, (2004) demonstrated that the MPN of coliform organism present in sewage contaminated water stored in copper vessel, was negligible within 36 hours of storage, indicating that copper has disinfecting property. Faundez et al, (2004) showed that copper sheets have an inhibitory effect on enteropathogens such as Salmonella enterica and Campylobacter jejuni.…”

A study was conducted to compare the effect of storage of water in copper, earthenware and stainless steel vessels on coliform count and aerobic plate count. Water samples contaminated with animal excreta was collected from farms and aerobic plate count and coliform count was estimated. The samples were then stored in copper, earthenware and stainless steel vessels for ten days at room temperature and the counts were taken on third, sixth and tenth days. Initial mean aerobic plate count of sample was 9.18±0.38 log 10 cfu/ml, which came down to 4.99±0.12 log 10 cfu/ml, 5.87±0.47 log 10 cfu/ml and 5.21±0.42 log 10 cfu/ml respectively, in copper, earthenware and stainless steel vessels on third day of storage. By tenth day of storage of water, copper vessel could eliminate 83 per cent of aerobic bacteria, earthenware vessel could eliminate 77 per cent of aerobic bacteria and stainless steel vessel could eliminate only 70 per cent of aerobic bacteria. Coliforms were completely eliminated from copper vessel by third day of storage. Whereas, earthenware vessel retained 66 percent of initial coliforms on third day of storage, and it took seven to ten days for complete removal of coliforms from earthenware vessel. Stainless steel vessel retained 23.5 per cent of initial coliforms on tenth day of storage. It could be concluded that use of copper vessels for storing drinking water in households is an effective water purification method. Highlights• Among copper, earthenware and stainless steel vessels, copper vessel is the best for storing water followed by earthenware and stainless steel vessels

“…Idika N et.al 1 showed effects of long storage of water in sterile clay pots and plastic containers by estimation of viable count after 2, 5, 10, 15, and 21 days of storage, here method of estimation was Miles & Mishra method. Mehta et al 9 demonstrated that the MPN of coliform organism present in sewage contaminated water stored in copper vessel was negligible within 36 hours of storage. Radha R. and Susheela P. demonstrated that most probable number of coliform organisms present in lake water stored in four different vessels showing decreasing succession of bacterial isolated it was copper vessels > clay vessels > stainless steel vessels > plastic bottles.…”

Water used for human consumption must be safe and free from microbes. Storing water in copper has been used since long time in India, also evident in ancient texts of Ayurveda. Present study aims to evaluate the efficacy of various water storing vessels in purifying drinking water especially in terms of antibacterial (anti-Escherichia coli) activity. The water was collected from Waghur River, Jalgaon and stored in different vessels for 5 days like copper, stainless steel and plastic.Bacterial growth was observed before and after storage. We found the significant reduction in the number of coliform bacteria in water stored in copper vessels than stainless steel and plastic vessels. We observed the benefit of using a copper-based device, which is effective and cheap for storage of water and can be used to made bacteria free water.
