Is Cologne Tap Water Clean and Drinkable?

Yes, the tap water in Cologne is generally clean and considered drinkable since it is regulated according to strict standards. The central body of regulations when it comes to drinking water is represented by the German Drinking Water Ordinance. The Drinking Water Regulation also requires continuous monitoring of contaminants that may end up in the tap water.

Here’s an example of a local water quality report: https://www.wassertest-online.de/wasserqualitaet/koeln.php

What you can immediately see is that the tap water contains nitrates. It’s below the “safe limit” but probably not advisable for babies and people with weak immune systems. This is a common problem across Germany due to the use of fertilisers in farming.

But clean tap water from the water supplier doesn’t necessarily mean that it’s clean in your kitchen. In many cases, harmful substances enter the drinking water due to faulty domestic installations, old fittings or bacteria infestation. Over 20,000 analyzed water samples provide a picture of the state of drinking water in German households. On average, every 5th water sample (21.54%) exceeded the limit value according to the TrinkwV 2001.

Furthermore not all water contaminants are tested for. Microplastics recently found in most bottled and tap water worldwide is currently not included in the local tests. PFAS found in the Venito region a couple of years ago is also not included in the standard tests.

What Do Locals Say about Cologne Tap Water?

How Can I Test If My Water Is Safe to Drink?

What about Bottled Water in Cologne?

There are numerous German manufacturers of bottled water, and most locals prefer mineral water over its counterparts. In fact, there are roughly more than 500 different brands of mineral water, whereas the price per liter ranges from 0.20 to 0.70 euros.

Nonetheless, it’s worth pointing out that the actual price of bottled water isn’t a legit indicator of its mineral component or anything of the kind. It is rather about the brand and its reputation.

So, one of the reasons why Germans prefer bottled water instead of tap water is the fact that mineral water is promoted as being healthy. Also, many choose sparkling water instead of still water because they assume that mineral water is more nutritious and beneficial.

In contrast with other European countries, Germany has an excellent recycling system, as you can recycle most plastic bottles at almost every supermarket. Despite this fact, the production of plastic still has a harmful impact on the environment – and in reality, less than 20% of that plastic is actually recycled into new bottles.

Furthermore, the process of manufacturing plastic, waste management, and its transportation will release a fair amount of CO2 into the air. This is obviously not good for the environment in the slightest.

When you’re thinking about environmental sustainability, it’s best to consider drinking tap water in Cologne.
