Your illustration shows a variety of vessels, the most common being used cooking oil containers. Any closed vessel like this is better than an open one but 'designed for purpose' blue water containers are much better though obviously more expensive. When I tried to introduce them in Guyana I was told (by an 'expert') that they would not work as some people would use them for diesel! Chlorination is a secondary issue after efficient collection and storage. The Hippo Roller is a great leap forward.
