In 2018 this large warehouse / logistics business experienced a problem with water in one of its fuel tanks that led to 25 customer vehicles breaking down. They called Adler and Allan to investigate. We visited the site to clean the tank and polish the fuel and gave the site a clean bill of health. Following this incident the client tasked us to suggest a solution to stop this situation happening again. We proposed a planned regime of cleaning and testing and are now contracted to manage their entire fuel infrastructure.
