A clean performance in Düsseldorf's hockey hall
At a cost of around ten million euros, the German Düsseldorf Hockey Club (DHC) has built a new clubhouse and hockey hall following the construction of outdoor tennis pitches and a tennis hall with three indoor pitches.
Measuring 40 and 70 m respectively, the drinking water installations in the hall are very extensive. Each with two dozen showers as well as some 20 washbasins and two dozen toilets and urinals, the facilities are well equipped.
The Hygiene+ concept from Viega
Since the hockey hall is not used to the same extent all year round, the quality of the drinking water can be impaired due to stagnation. Moreover, the hall with its own gastronomy area is a "public building" which means that a complete water exchange is prescribed at least every 72 hours. Ensuring compliance with the flushing plan manually is not expedient in such a facility. And, as such, an automatic solution was sought.
With the decentralised Hygiene+ concept from Viega the completely looped-in extraction points are protected from stagnation. In addition, the Raxofix piping system guarantees a reduced volume and optimal flow. The urinals are fitted with electronic siphon sensor technology and flush automatically if not used for 24 hours. The WCs come with electronic flush actuation with the Hygiene+ function which triggers the "small" flush volume after predefined time intervals.
A different solution has been found for the washbasins which are used far less frequently. The extraction points are connected to the main distributor via ring systems and press-in nozzles are positioned between the branched off T-pieces based on the Venturi principle: Every time water is extracted, as per the Venturi principle a small pressure difference in the ring system is automatically created which causes the entire volume up to the individual extraction point to be completely exchanged within 24 hours.
