WSSC Becomes Official

Maryland Gov. Emerson Harrington signed the Act of 1918 that formed the Washington Suburban Sanitary District. The measure took effect May 1, 1918.

Maryland created Washington Suburban Sanitary Commission (WSSC) to oversee the Sanitary District and play a vital role in the public health of the region. At the time, only 30,000 people lived in the service area. By 1933, a mere 15 years later, the population more than doubled to 65,000. Initially, Prince George’s and Montgomery counties’ service area covered only the more populated 95 square miles close to D.C. One hundred years later, WSSC services almost the entire acreage of the counties, with exception of Bowie and Rockville for water service.
