Do you control cross connections to the last outlet of the customers tap?

Per IEPA Regulations, the water purveyor is responsible to the curb stop of each connection. Per Dave McMillan of the IEPA: 'To have an effective program, a community will need to recognize that their water supply is ultimately responsible for protecting their distribution system. A significant point that must be recognized is that the community water system is not responsible for what goes on within an individual service connection.' Your ordinances may be stricter and require 'isolation' and/or 'containment.'
