First Flush Systems

A first flush system – also called a diversion system or diversion valve – diverts water from a contaminated surface, like an unroofed wash-down bay to another source of discharge. The first pass of rainwater over a roof clears away sediment, oils, and other contaminants, before storing the water in a tank or liquid holding structure.
