Wastewater Storage Tanks

Wastewater storage tanks are sealed containers designed for the temporary storage of domestic or commercial sewage and effluent. Unlike septic tanks or treatment plants, these tanks do not treat wastewater but provide safe holding until it can be emptied by a licensed waste contractor. Our range includes Graf Carat and Platin tanks, suitable for underground installation and fully compliant with local regulations.
