Chlorine in drinking water: Enercity protects Hanover from bacteria!
Enercity has been chlorinating drinking water in Hanover since July 20, 2025 to ensure quality. Be careful with smell and taste.
Chlorine in drinking water: Enercity protects Hanover from bacteria!
The Hanover region must prepare for a temporary change in water quality. Chlorine has been added to drinking water since Thursday to ensure quality. The reason for this step are abnormalities in routine water tests in which increased bacterial levels were found. This information was transmitted to the Hanover Region Health Department, which coordinated appropriate measures with Enercity. However, according to ndr.de, drinking water can still be drunk and used safely.
The chlorination will be carried out in particular at the Elze-Berkhof waterworks and is expected to continue throughout the weekend. This involves a finely dosed addition of chlorine, which can be noticeable in terms of taste and smell, but Enercity ensures that high drinking water quality is ensured. The affected areas extend across northern parts of Hanover; exact details of the affected locations cannot currently be disclosed. Enercity has provided drinking water to over 650,000 people and, with modern filtering, can even treat water for up to 700,000 people.
Background on drinking water quality
One thing is clear: a clear and healthy water supply is of great importance for the population. Over the last few decades, no harmful concentrations of pollutants have been found in drinking water in Germany. This is mainly due to the better understanding of water transmission, which was acquired around 1900 after the cholera epidemic, and the continuous education about health risks, as t-online.de reports. The Federal Environment Agency emphasizes that well-filtered and disinfected drinking water rarely contains pathogens, although long-term effects of pollutants in small quantities can still be dangerous.
The impurities that lead to the use of chlorine are usually associated with microbiological contamination, which, as we know, can cause serious disease outbreaks. This makes regular checks all the more important to ensure that the quality of our water remains high. Enercity and the health department are currently working to provide information about the cause of the bacterial contamination.
There will be more information about this in the coming week. The health of citizens is paramount and we can be confident that the necessary steps are being taken to ensure this.
