Well-functioning V / E. Fresh water costs € 1 (each) just like dumping the toilet cassette ... is the type V / E with shutters. Unfortunately no floor inlet, although operated by professionals (located directly at the sewage treatment plant) - because the station is at the small driveway to the company premises. You can turn / turn 20 meters further in front of the sewage works gate. For the gray water one of the gullies has to be used ... for example the one five meters in front of the station :-)
