Sewer equipment cleaning systems and methods of use are described. The sewer equipment cleaning systems may include an additive delivery system having multiple additive tanks and an additive tank pump configured to deliver additive into a wash system residing on a sewer inspection vehicle (SIV). The SIV is typically equipped with an inspection camera and one or more cables connecting the camera to the SIV. The wash system may be used for rinsing contaminants from the camera and cables upon their withdrawal from a sewer system. The additive delivery system can be plumbed into the SIV wash system in order to deliver additives, which may include surfactants or disinfectants, to water from the wash system, without adulterating water in the wash system water tank.
