We handle liquid waste across from wide range of high risk industrial environments, bringing specialist plant and equipment and trained crews to ensure safe, compliant and efficient removal.
InterGroup delivers expert liquid waste services nationwide – supporting councils, businesses, industrial sites and utility owners with collection, transport, treatment and disposal.
Whether it’s routine servicing or emergency response, our fleet of vacuum trucks and tankers are equipped to handle a wide range of liquid waste streams. We also offer environmental reporting, traceability and proactive scheduling to help you meet compliance requirements and minimise risk.
