If you filter the water from your own well mechanically, you can even achieve the quality of drinking water. Depending on the requirements, however, this also entails costs of several hundred euros.
In a nutshell
- Well water is relatively easy to filter on a mechanical basis
- A special filter system is required for this
- The system must be integrated into the pipe from the well to the house
- The cost of this depends on the type of filter and whether you need a professional to install it

Having your own well can be worth its weight in gold. It definitely makes you independent and helps to save on water charges. The water from your own garden is always suitable for service water. However, the situation is different when the quality of drinking water is to be achieved. Well water is very often not enough. A filter can help here. There are basically three options:
- Filter to retain fine sand
- Filter against iron and manganese
- Universal filter for drinking water quality
Before you start installing a filter, a professional water analysis is essential. It shows how the water quality actually is and where it may need to be reworked. Based on the analysis results, you can then decide on a specific filter or filter system. If you only want to hold back fine sand, you can use a very simple filter. It basically consists of a very fine sieve that filters the sand out of the water in a completely natural way. On the other hand, anyone who actually aims for drinking water quality needs a relatively complex system that works to a certain extent mechanically.
Notice: Filters for drinking water quality always result in follow-up costs. The filters work with special inserts (cartridges) that have to be changed regularly.
Filters for drinking water
Drinking water has to meet certain requirements in this country. This is regulated in the Drinking Water Ordinance, which sets very narrow limit values for many ingredients. These substances and potential pathogens include:
- ammonium
- iron
- manganese
- nitrate
- nitrite
- E coli bacteria
- enterococci
In addition, drinking water must have a pH value between 6.5 and 9.5. Depending on how polluted the well water is, the respective filter must be selected. However, there are also relatively complex filter systems that, to a certain extent, cover possibilities. It almost goes without saying that such systems are to be preferred if drinking water is to be treated permanently. Since the water quality can also change over time, you are prepared for all eventualities.
Tip: Before you decide on a filter or a filter system, you should definitely seek detailed advice from an expert. And of course the water has to be tested in advance.
investments
How much a filter or a filter system costs depends on the respective version and the manufacturer. General information on this is not possible. A simple iron filter, for example, is commercially available from around 50 euros. For complex systems, on the other hand, several hundred euros can be incurred. An important point in this regard is also the installation of the filter. The question is: Can and should it be done by yourself or do you need an installer for it. A professional is always recommended if the well water is to be used in the house. However, this also entails considerable additional costs, which are largely dependent on the amount of work involved.
