Rainwater was to be used to supply 70 toilets in the school building and 8,400 m2 of green space outside the school.
Due to the limited space available, the cistern was planned in stages in order to make the best possible use of the available installation space.
To ensure consistently good water quality, an ARIS CLEAN filter was installed upstream of the cistern.
In this way, the water is fed into the cistern as cleanly as possible and thus retains its good quality, even over long periods of time,
