Electric sewer cleaning vehicle goes into production 

KAISER has started production of its first fully electric sewer cleaning vehicle, the AquaStar EV.  

Sewer cleaning operations are power- and energy-intensive. In an exclusive partnership with electric truck manufacturer Designwerk, KAISER has jointly addressed these technical challenges. 

Users of the AquaStar EV can rely on KAISER’s high jetting and vacuuming capacity in combination with water recycling.   

“With our exclusive Swiss partner Designwerk, we’ve found an e-mobility expert who offers the right solution for our energy-intensive application,” KAISER Group chief technology officer Daniel Laubscher said. 

The high-voltage AquaStar is equipped with a battery capacity of up to 508 kilowatt hour (kWh). This enables the vehicle to operate for up to eight hours without having to recharge.

Charging capacity is up to 350 kilowatts (KW). The battery takes roughly one hour and 20 minutes to reach full charge. 

 Two high-performance electric power take-off drives ensure a jetting capacity of up to 300 litres per minute and suction power of up to 3,100 cubic meters per hour (m3/h). 

The electric drive has a significant impact on consumption and emission values, particularly for sewer cleaning vehicles that are deployed daily.  

On average, the KAISER AquaStar EV saves 21,000 litres of diesel a year. Depending on the energy mix, it reduces carbon emissions by up to 80 per cent viewed over the entire lifecycle of the vehicle. 

 This makes the electric sewer cleaner an interesting option for private customers and local governments who are aiming to equip their operations for the future, or who work in conurbations with restrictions on CO2 emissions.  

Thanks to water recycling and electric drive, the KAISER AquaStar EV consumes almost no resources.  

“Sustainability plays a major role for our products. We are particularly proud of also being innovation driver and technology leader in the EV sector,” Laubscher said.
