The Metropolitan District Commission of Connecticut (MDC) is a public non-profit municipal corporation chartered by the Connecticut General Assembly in 1929 to provide drinking water and sewer service to the Hartford area. The original agreement tied together the water systems of Hartford, Bloomfield, Newington, Wethersfield, and Windsor. The MDC currently serves eight towns in the Hartford area. The MDC is run by a 29-member board of commissioners; 17 of which are appointed by the member towns, eight by the governor, and four by legislative leaders. The current Chairman of the MDC Board is William A. DiBella.
