Areas of application
Drinking water suitable flat hoses for temporary supply of potable water & flexible hose risers for pumping well water.
Product overviewAccess to clean drinking water is a significant component of infrastructure worldwide, and large-scale water distribution is a challenge.
Flat pressure hoses for potable water supply can be used for static and portable water sources, often replacing unsafe, traditional water transport methods.
For the population, access to clean, potable water minimizes the risk of waterborne disease transmission.
For events, large-scale events, festivals, city festivals, in contrast to drinking water supply emergencies, the aim is to provide drinking quality water to many people for a short period of time in places that are not connected to a supply network.
For this purpose, highly flexible pressure hoses are planned for the provision of drinking water by water suppliers, municipalities and event organizers.
They are quickly laid, robust, flexible, easy to clean and space-saving to store.
Water, the number one basic foodstuff, does not always come from the drinking water pipeline. Hose systems are used as temporary emergency lines or bypasses for general drinking water supply in civil protection, disaster management and the military.
Cut off by a burst water main or destroyed water pipes, those affected are soon literally left high and dry. An emergency water supply secures access to drinking water and diverts wastewater when a normal supply of water is endangered, restricted or impossible.
In the field of well construction, when wells are developed as a source of drinking water, the potable groundwater must be pumped from the water table to the surface. By using flat, highly flexible pressure hoses as hose risers, the water quality is protected from contamination. Loops on the hose riser suitable for potable water guide secure the pump cable.

Compared to temporary rigid drinking water pipes, GH drinking water hoses are flexible and pliable despite their resistance to mechanical and weather influences. Unlike pipelines made of individual sections, the use of drinking water hoses does not lead to corrosion and, as a result, to contamination and leaks. What makes a safe drinking water hose? Where can flat hoses be used effectively for drinking water supply?
Not every water hose is suitable and approved as a drinking water hose. The raw materials from which the hose is made must be on a positive list and the finished hose must pass various tests to be approved.
GH Drinking water hoses >
A drinking water hose is - as the name suggests - a hose designed to transport drinking water. It can be used as an emergency water supply in crisis areas on a long-term basis as well as on a short-term basis in the event of a water pipe burst or for general water supply at events. With additional loops for pump cable routing, it transports drinking water in well construction as a flexible hose riser. It meets all food hygiene requirements.
GH drinking water hoses can be used in the temperature range down to - 20 degrees Celsius and maximum 75 degrees Celsius:
GH potable water hoses are constructed of special TPU (potable water PU) and a circular woven pressure body made of high-strength polyester yarn. In the single-stage extrusion process, the TPU penetrates through the fabric liner and the latter is completely enclosed in a centered manner. The drinking water hose is highly abrasion-resistant and virtually resistant to external mechanical damage. It scores with service lives of a factor of 10 compared to coated hoses.
The Storz coupling with stainless steel wire is also the standard in the field of drinking water hoses. However, there are clear recommendations from the DVGW (German Technical and Scientific Association for Gas and Water) for drinking water installations with regard to hygiene, but also with regard to their properties - depending on the place of use and service life.
