In the May 18, 2021 special election, Green District voters approved of the formation of a joint water and sanitary authority, and concurrent dissolution of Roberts Creek Water District and Green Sanitary District. 

Every spring, Douglas County Fire District 2 conducts its hydrant flushing maintenance.  In conjunction, GAWSA will be flushing main lines throughout the Authority.  GAWSA turns valves and flushes different areas of the main water lines to further eliminate sediment and deposits in the water, and reduce water stagnation. Flushing should take between two to four weeks.
