From Roman aqueducts to modern water supply: The history of drinking water in Mainz

Drinking water in Mainz has a long historical significance and played an important role in the city’s development. Since ancient times, Mainz has depended on a reliable source of water to meet the needs of its population.

As early as Roman times, there were the first aqueducts that brought drinking water from surrounding springs into the city. These aqueducts were a masterpiece of engineering and ensured that Mainz was supplied with sufficient fresh water. Some of these Roman aqueducts are still preserved today and can be visited.

In the Middle Ages, numerous wells were built in Mainz to ensure the water supply. These wells were of great importance for the daily life of the people. They were operated by the city government and ensured that the population had access to clean drinking water.

Over time, water supply techniques evolved. In the 19th century, the first waterworks were built to filter and purify the drinking water in Mainz. The introduction of piped water supply made it possible to bring water directly to households. This was a great advance and greatly improved the living conditions of the population.

In the 20th century, waterworks were modernized and the quality of drinking water was further improved. Today, drinking water in Mainz is subject to strict controls to ensure that it meets the highest hygienic standards. It is extracted from several deep wells and distributed to households through a sophisticated network of pipes.

The city of Mainz attaches great importance to a sustainable water supply and implements measures to conserve water resources. This includes, among other things, the protection of the source areas and the promotion of a conscious use of drinking water.

Overall, it can be said that drinking water in Mainz has a long history and has always played an important role in the development and well-being of the city and its residents. The constant improvement of water supply technologies has contributed to thistragen, dass heute hochwertiges Trinkwasser in Mainz zur Verfügung steht.

Efficient water treatment in Mainz: processes and technologies for high-quality drinking water”

The main drinking water supplier in Mainz is Mainzer Stadtwerke AG. As a municipal company, it is responsible for the city’s water supply. Mainzer Stadtwerke obtains its raw water mainly from groundwater, which is extracted through deep wells. These wells are located in carefully selected areas where the groundwater is of good quality and sufficient quantity.

Drinking water demand in Mainz varies according to population and industrial activities. The city of Mainz has a population of approximately 220,000. The average daily drinking water demand per person is about 120-140 liters. This demand includes consumption for households, businesses, and public facilities.

To meet the drinking water demand in Mainz, Mainzer Stadtwerke operates several water treatment plants. In addition to the treatment steps already mentioned, various chemical processes are also used to remove impurities and ensure water quality. These include, for example, flocculants that bind suspended solids and pH adjustments to bring the water into an optimal range.

Mainzer Stadtwerke also relies on continuous monitoring of drinking water. Regular sampling and analysis is performed to identify potential contaminants or deviations from drinking water standards. This enables early detection of problems and, if necessary, the initiation of measures to improve water quality.

Water treatment in Mainz is based on a multi-stage process aimed at converting the raw water from the deep wells into high-quality drinking water. Various processes and technologies are used to ensure efficient purification and disinfection.

• Raw water extraction: The raw water is extracted from the deep wells. These are wells placed in carefully selected areas to extract clean groundwater. The raw water flows into the water treatment plant.
• Coarse filtration: The raw water first goes through coarse filtration to remove larger particles such as sand, silt or other solids. Screen filters or sand filters are used for this purpose.
• Flocculation: To remove finer particles and impurities, a flocculant is added to the water. This flocculant forms small particles, called flocs, which combine with the fine suspended particles in the water. This makes these particles larger and easier to separate.
• Sedimentation: After flocculation, the water enters large basins where the flocs settle to the bottom by sedimentation. The water remains still during this process, allowing the flocs to settle to the bottom of the basin. The clear supernatant is passed on for further purification.
• Filtration: The water now passes through fine-pored filters that remove any remaining solids and particles. Different types of filters can be used, such as activated carbon filters or sand filters. These filters absorb or sieve the remaining impurities from the water.
• Disinfection: To kill harmful microorganisms, a disinfectant is added to the treated water. In Mainz, disinfection is usually done by chlorination or ozonation. This step ensures a hygienic quality of drinking water and protects against pathogens.
• Fine filtration: After disinfection, the water is subjected to further fine filtration to remove any residues or impurities. Filters with even smaller pores are used to achieve a high purity of the water.
• pH value correction: The pH value of the water is adjusted to bring it into the optimal range. This serves the stability of drinking water and ensures good compatibility
• Storage and distribution: The treated drinking water is stored in special storage tanks or elevated tanks to ensure a constant supply. From there, it is distributed via a sophisticated network of pipes to households, businesses and public institutions in Mainz.

Water treatment in Mainz is subject to strict controls and monitoring to ensure compliance with drinking water standards. Regular sampling and analysis are carried out to check the quality of the treated water and detect potential contamination at an early stage. The water treatment plants in Mainz are continuously maintained and optimized to ensure an efficient and reliable water supply.

In summary, Mainzer Stadtwerke is responsible for being the main supplier of drinking water in Mainz. They obtain raw water from deep wells and use various treatment methods and chemical processes to ensure high water quality. Continuous monitoring of the drinking water ensures compliance with legal requirements and the health of the population.
