The FIA has put tyre-particle filters in Zandvoort's drains, and the plan is to leave them there
Two prototype units sit in the circuit's stormwater network, covering about 3,300 square metres around the pit lane and the Tarzanbocht. The FIA's head of R&D frames the target as the road traffic on the network around the track rather than the 22 cars on it, and says the filters should stay behind after the race leaves. Formula 1 leaves Zandvoort for good on Sunday.
