After two and a half years of construction, German carwash ‘aha’ has now completed a project for the use of rainwater to clean its own sweepers.

With measures to save energy, self-sufficiency and the use of electric mobility, this project makes a significant contribution to Hanover’s climate protection program, according to a statement from aha. One element of the economical use of drinking water is the use of rainwater to clean the sweepers.

To clean the inside drums of the sweepers, 220 cubic meters of rainwater is collected and used for cleaning via a hose system. This significantly reduces the consumption of drinking water.

“The construction of this operational facility in passive house standard is a lighthouse project for climate protection in Hanover,” said Hanover’s Lord Mayor Belit Onay, summarizing the contribution of this project to climate protection in the city.
