Designwerk and KAISER build e-truck for sewer cleaning


Winterthur/Schaanwald – Winterthur-based e-truck manufacturer Designwerk and KAISER, Liechtenstein-based specialist for sewer cleaning and industrial waste disposal, are putting the first electric vehicle for sewer cleaning with water recycling into series production. It reduces CO2 emissions by up to 80 percent.

Designwerk and KAISER present the first electric sewer cleaning vehicle with water recycling until June 9 at the trade fair for the public sector, Suisse Public, in Bern. According to a media release, the KAISER AquaStar EV based on the Designwerk e-truck MID CAB Sewer Cleaner 6x2R is going into series production.

“With our Swiss exclusive partner Designwerk, we have found an e-mobility expert who offers a suitable solution for our energy-intensive application,” the technical manager of the KAISER Group, Daniel Laubscher, is quoted as saying. Among other things, this consists of a battery capacity of up to 508 kilowatt hours. With this, the vehicle reportedly operates for up to eight hours without recharging. The charging power is up to 350 kilowatts. The battery reaches its full charge level in around 80 minutes.

The KAISER AquaStar EV is expected to save an average of 21,000 liters of diesel per year and, depending on the power mix, reduce CO2 emissions by up to 80 percent over its entire life cycle. According to Designwerk, this makes the electric sewer cleaner interesting for private customers and municipalities that want to work in a particularly future-oriented manner or are operating in conurbations with CO2 limits. Thanks to water recycling and e-drive, the all-electric vehicle is virtually resource-free. ce/mm
