Hygiene in the drinking water tank: For pressure equalisation when the water level in the water chamber changes
Our ventilation and air extraction systems
Tank ventilation and air filtration in drinking water tanks
Filtering of supply air reduces hygiene risks
Typically, the water level of a tank is constantly in motion. While air flows to the outside during filling, the water storage tank draws in ambient air when it is emptied. During this breathing process, particles contained in the air also enter the drinking water. As this also contains organisms such as germs, viruses, spores or pollen, this results in a considerable hygienic burden. An average annual load of 21,000 mg of dust or 1,680 billion germs is calculated for a 500 m³ tank. Even the elevated tank on a greenfield site is not spared from this.
HEPA filters - which have also proved their worth in operating theatres in hospitals - ensure really clean air. If farmers also spray liquid manure, only an additional activated carbon filter can help. And the costs? The surcharge from a coarse filter to a HEPA filter is minimal. And the service life of several years in some cases should not deter any operator from investing in the hygiene safety of their water storage tank.

What shape and size should my manhole cover be?
Manholes vary greatly depending on the intended use and area of application. Find out about the options and requirements here.
What material should a manhole cover be made of?
Durability, corrosion resistance and many other aspects speak in favour of using stainless steel. Find out all about its advantages for your project here.
How do I seal my manhole properly?
Does my manhole need insulation and what does watertightness mean? Here you can read all about the correct sealing of manholes.
How do I protect my shaft against access by unauthorised persons?
Every operator is responsible for the safety of their shaft. It is therefore extremely important to find out about access and to equip the shaft accordingly.
What do I need to consider when entering the shaft?
There are strict laws and standards for accessing manholes. Find out about possible manhole accessories to avoid accidents.

Producing high-quality drinking water and distributing it safely to consumers
Drinking water is fresh water that is suitable for human consumption if defined requirements are met.
The quality requirements for drinking water differ from country to country, and for Germany the Drinking Water Ordinance (TrinkwV) applies here, among other regulations.
Drinking water abstraction, treatment and distribution
Extraction from wells: Wells can be several hundred metres deep and are used to extract groundwater. Depending on the depth of the well and local conditions, water quality varies and the water may need to be treated further.
Extraction from springs: Spring water is groundwater that comes to light. The water quality depends, among other things, on whether the spring is fed by deep groundwater or by less deep surface water. The risk of possible adverse health effects is greater in the case of near-surface water.
Extraction from surface water: Drinking water can be obtained from rivers and lakes. Because of the substances that are often present, it is usually necessary to treat the water before it can be used. Seawater is also a common source of drinking water in many countries, with technically complex and energy-intensive seawater desalination plants being used.
Storage and distribution: The drinking water is made available to the consumers in the required quantity and pressure as well as the necessary quality via a water distribution system consisting of storage tanks, pressure boosters and pipelines, among other components.
