With modern systems they will be USEPA or DVGW verified and this will incorporate the control system to calculate the reduction efficiency dose(RED) from the flow, UV intensity and transmissivity so that the effectiveness is as much known as it is with chlorine, particularly as there is no risk of bypassing or contamination of the contact tank.
