Each year, BWSC and other water distribution utilities and environmental groups across the United States celebrate National Drinking Water Week during the first full week of May. A joint congressional resolution declared the event a national observance in 1988 and thousands participate every year. The aim of National Drinking Water Week is to reach out to young people to increase awareness of and involvement in water issues.
