Washing facility for buses

Project info

One of the first rainwater systems built by WISY for a major industrial customer was installed in Hanau. Since 1992, the city buses of Hanauer Straßenbahn GmbH have been washed with soft rainwater. Rainwater is collected from a 1,080 m² section of the roof surface of the workshop hall. The annual rainfall of 650 mm provides enough rainwater to wash 70 buses per week and transport passengers in sparkling clean vehicles.

Project information


The operator of the bus wash uses the lime-free rainwater for the last wash cycle. All the water of around 2,000 litres per vehicle wash is collected again, cleaned and stored for further washing cycles. Three plastic containers of 2,000 litres each are available for this purpose in the plant's operating room. The amount of water lost from the cycle during each wash cycle is replenished from a 2 m³ rainwater buffer tank.

The rainwater system has six downpipe filters, two of which are connected to three downpipes, one above the other. The filtered water is stored in an underground 40 m³ cistern and pumped into the intermediate storage tank in the plant room as needed.
