Fire water supply according to DIN 14230

To ensure that you can guarantee a fast initial supply of fire water in the event of an emergency, we offer you different variants for implementation. We offer you underground tanks, which come into play when you want to keep the necessary volume available in the most space-saving way possible. Our GRP tanks with a storage volume of 15 to 250 m³ represent one solution option.

System separation to DIN EN 1717

The INTEWA system separator "SEPAMAT" isolates the drinking water system from the consumer. It protects drinking water against contamination caused by backflow of pollutants from the consumer point of use. System separation is installed between the municipal drinking water supply and one or more fixtures. These must be separated in accordance with Category 5 of the current drinking water regulations contained in DIN EN1717.
