Great free sani station, +nothing+ wrong with it, but slightly different from usual: - Waste water + toilet discharge into the same spacious pit (with grate) -Lift the approx 1mtr-wide cover plate at the bottom of the column: then the flushing of the well switches on until you slide the plate back -Under the opened plate is a water hose with an open/close spray head (without standard Gardena connector) to clean the toilet tank + pit -On the side is a door + cabinet, containing drinking water (with Gardena) Great!
