balling

A hydraulic cleaning method using the pressure of a water head to create a high cleansing velocity of water around a cleaning ball in a wastewater collection pipe or storm drain. In normal operation, the ball is restrained by a cable while water washes past the ball at high velocity. Special cleaning balls have an outside tread that causes them to spin or rotate, resulting in a scrubbing action of the flowing water along the pipe wall.
