In hilly Wuppertal, AGR-KAKO has been a recognised partner for decades for local authorities and companies in the region when it comes to the disposal of acids, alkalis, emulsions, solvents, separator contents and other liquid hazardous materials or faeces. The "Super-Sauger 2800" from Schrader T+A Fahrzeugbau is used for this work, which can get into every corner thanks to its electro-hydraulic Active Reverse Control auxiliary steering system from BPW.
