Please note that chemicals can only be added to drinking water in a building by an approved permittee or by a trained and qualified employee of a permittee. The system for adding chemicals to drinking water shall be designed, installed and maintained in accordance with the manufacturer's specifications and applicable industry standards to ensure proper chemical dosage and operation. The system must be tamper proof with maximum feed pump capacities adjusted to prevent any overfeed of chemicals and must be installed to prevent back-siphoning.
Prior to operation and monthly thereafter, the permittee must confirm that the drinking water after being chemically treated, complies with Subpart 5-1 of the State Sanitary Code. Records of water sampling and analysis and maintenance records including all personnel who work or maintain the chemical addition device, dates and times of service and the amount of each chemical applied to the drinking water supply being treated must be maintained on file for 5 years.
