Where does Chelmsford's drinking water come from?

78 percent of residents in Chelmsford receive their water from the Chelmsford Water District.  The District’s system is made up of twenty (20) wells and are located in two River Basins; the Concord River Basin and the Merrimack River Basin.  After it is pumped from the ground the water is sent to one of the treatment plants and then on to homes, businesses and schools.
