*What is Blue Water? 

In early 2019, water companies issued new guidance on the subject of a cistern backflow problem, which has become known as ‘blue water’. 

The problem was identified after customer complaints of blue water coming out of their taps. Careful investigation revealed that in certain conditions ‘blue water’ created by cistern cleaning tablets was able to flow back into the main supply pipe and contaminate the customers’ water supplies.
