System separation for drinking-water protection according 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.

SEPAMAT Applications

Medical Professionals
Agriculture / Slaughterhouses
Irrigation Systems
Laboratories
Laundromats
Car-wash Facilities

and many other applications such as crematories, sprinkler systems, fire-water and domestic water systems (rainwater and greywater).

SEPAMAT, certified security

Liquids of category 5 may constitute a health hazard for humans due to the presence of microbial pathogens or virulent communicable diseases. The european standard DIN EN 1717 requires the so-called "air gap" for separation between drinking-water and the consumer.

In the DVGW-certified SEPAMAT system separators, this "air gap" is already integrated. According to the standard, only the "air gap AA and AB" is permitted for the replenishment of drinking-water during water shortages.

1: Drinking-water 3: Maximum water level
2: Overflow opening 4: Air gap

The integrated pump delivers water to consumers, as required, from a separation and feed tank. The water level in the separation and feed tank is regulated by a float valve. The drinking-water network and emergency overflow are connected to the separation tank.

Contact between the consumer water and drinking-water supply is prevented. The SEPAMAT system separator thus meets the world's highest safety standards.

The possibility to save drinking water has enhanced strongly the last years.
