- Wastewater produced by washing carts must not be discharged into a storm drain or seep into the ground.
- According to Aachen's road regulations, individual vehicle surface washing is only permitted on public roads using pure water without washing additives and without the use of a high-pressure cleaner or hose.
- On Sundays and public holidays, the washing of vehicles by hand is generally prohibited under the Sundays and Public Holidays Act for the state of North Rhine-Westphalia.
It is therefore only permissible to wash carts in public areas with a sponge or on your own property if the floor inlets are connected to a sewer.
