Hattersheim waterworks shines: modern technology for pure enjoyment!
The Hattersheim waterworks will be modernized in 2025 with new filter systems to improve water quality in the region.

Hattersheim waterworks shines: modern technology for pure enjoyment!
The old Hattersheim waterworks, a remarkable industrial monument, has reopened its doors after years of inactivity. Built in 1905, it originally served to supply both Frankfurt and Hattersheim with first-class drinking water. With the introduction of modern technology, a new era is ushered in that relies on modern water treatment. As the FAZ reports, the waterworks will in future be supported by a new type of reverse osmosis system, which was put into operation in April of this year.
In recent decades, the waterworks had played little role as water quality raised concerns. But the abundant groundwater of the Hattersheim wells, coupled with modern technical upgrades, once again offers a real solution. The construction of a new filter system next to the old waterworks secures the supply and meets the demands of the Darmstadt regional council regarding the need for a replacement supply, especially in view of the planned western regional bypass.
Modern technology for clean water
A central component of the new technology are the advanced vacuum pumps, which enable more efficient water pumping. The reverse osmosis system can achieve an impressive 77 percent drinking water yield, which significantly improves the quality of the water. In this process, water is forced under pressure through a semi-permeable membrane, where harmful particles and many ionized substances, such as the ACWA Service explained.
The process begins with sand filters that separate coarse contaminants. This is immediately followed by reverse osmosis, in which microparticles such as drug residues and microplastics are filtered out. Some systems also use post-filters and remineralization to improve the taste of the water. This goes hand in hand with the use of activated carbon, which adsorbs dissolved organic substances and ensures pleasantly fresh water.
The way into the future
The commissioning of the waterworks is not only part of the regional drinking water supply, but also as a response to the growing challenges arising from climate change and urban growth. Frankfurt is growing, and with increasing dry spells the need for reliable local water sources is becoming increasingly clear. Thanks to the regulations of the regional council and the commitment of the city, the operation of the waterworks will not be stopped even after the regional bypass has been completed.
In addition to technical advances, modern reverse osmosis systems are also a sensible investment for consumers. They offer a sustainable solution to improve water quality and long-term cost savings, as bottled water purchases are far more expensive. Loud AquaKnowledge There are many models on the market with excellent performance characteristics that are user-friendly both to purchase and to install.
In summary, the Hattersheim waterworks will be repositioned with state-of-the-art technology that is in line with the increasing requirements of the region. The combination of historical heritage and futuristic water treatment could become a model for future projects in the entire Rhine-Main area. There is something for everyone who wants good and safe drinking water.
