Abstract
A large bore mobile vacuum system is used with special large bore vacuum adapters to enable a method and system for cleaning ground tanks used to store wastewater. The ground tank cleaning method and system may be safer and more efficient that conventional methods by enabling a human operator to physically remain outside of the ground tank, while preventing the contents of the ground tank from being exposed to the environment during the ground tank cleaning.
