Provide for the maintenance of a continuing program of cross connection control which will systematically and effectively.
Cross-Connections A cross-connection is a link between the potable water supply and contaminated water (e.g. sewage, chemicals, recycled water). Cross-connections are caused by problems in the design or repair of the plumbing system or by workers who . connections. Most cross-connections occur beyond the customer service connection, within residential, commercial, institutional or industrial plumbing systems.
