Cutting-edge technology greywater recycling


05'19 / The cutting-edge technology that pays off: Commercial greywater recycling for high demand

New: The powerful SEPAMAT Profi and the WIKI knowledge portal


02'19 / The INTEWA SEPAMAT system separators protect your drinking water from contamination. The backflow of substances from the consumer side into the urban drinking water network is safely and reliably prevented by system separators. Thus the use of these systems serves the protection of your health! If you need a higher efficiency or the given space conditions do not allow a Duplex or Triplex system, our Profi is called to action! The SEPAMAT Profi reliably and comfortably secures the drinking water network according to DIN EN 1717 / DIN 1988-100.

Innovation in international service


01'19 /In the middle of this year, more than 350 people lost their lives in devastating floods caused by an extremely heavy monsoon in the state of Kerala in southern India. More than 1.2 million people were evacuated from their homes and had to be accommodated in emergency shelters. Here the INTEWA water treatment system, AQUALOOP Tap, could be brought to the Kerala disaster area for emergency relief.

We're going deep!


12'18 / INTEWA has installed various water treatment systems and associated cisterns for optimized treatment and in depth research and testing purposes within the scope of civil engineering at the new company building "Auf der Hüls". In this way, INTEWA generates a large part of the drinking and non-potable water required by the company from its own treatment technologies.

How do rainwater harvesting and green roofs fit together?


11'18 / Due to the implementation of the new DWA A102 (technical guidelines for mixed and precipitation water introduction), green roofs are becoming more important. But how do green roofs and rainwater harvesting fit together? INTEWA wants to answer this question and develop solutions with the installation of our own green roof on the new company building.

Rainwater infiltration pays off!


03'19 / By using a rainwater infiltration system, you actively free yourself from the stormwater fee. This is worth it! INTEWA offers you rainwater infiltration systems and rainwater retention systems for a wide range of area sizes both as packages for single-family houses and systems for commercial projects. The INTEWA systems are suitable for new buildings or for retrofitting in existing houses. We have the right solution for every need and offer you the best price-performance ratio!

New name and huge operating range: the INTEWA PROFI pump and control centres expand the current RAINMASTER series. There, where the capabilities of the INTEWA RAINMASTER Favorit are inadequate or the area requirements do not allow for a Favorit Duplex or Triplex system, the PROFI booster stations supplement a higher capability range with perfect and efficient performance.

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.

AQUALOOP-Tap 1600 is a filter for disinfection of water. The cleaning principle is based on the INTEWA AQUALOOP ultrafiltration membrane technology, upon which substances in the water, like microorganisms such as bacteria and viruses, are withheld. The filtration result is clear, hygenic water.

Hops, malt, yeast and last but not least, water - after 500 years of the German Beer Purity Law, beer is very popular. A growing movement called "Craft Beer" brews beers with a wide range of tastes and unique aromas and they do it with enthusiasm. Hops, malt and yeast are brought together in a creative way to develop something new. The fourth factor for a good beer is water. Breweries usually have their own, strictly guarded water sources to brew their unique beer.
