Cold water storage tank cleaning

Water storage tank cleaning is a very large part of our company, we currently clean and chlorinate around 150 water storage tanks every year in and around the UK.
These tanks are used to supply drinking water so need to be tested and certified before human consumption.

You probably think its fine to leave your tank and not worry about cleaning it! well you would be wrong, all potable water tanks need to be cleaned and chlorinated each year. It is surprising how many people think it’s an unnecessary task – just because you don’t see the tanks every day, to notice what’s happening in them.
