The MDC’s online interactive map includes an inventory of over 100,000 drinking water service lines within the MDC’s distribution system. A water service line is the pipe that conveys water from the water main in the street into a property. The map is provided as a service to customers and in compliance with the EPA’s Lead and Copper Rule Revision.
