          A Tour of the Water Purification Facility
          During the summer and fall, monthly Monday evening tours of the Walter 
          J. Sullivan Water Purification Facility are offered by Cambridge Water 
          Department staff and Friends of Fresh Pond Reservation. Here, participants 
          standing on the balcony are looking at the floor map in the lobby. The 
          map illustrates Fresh Pond and the underground pipelines that carry 
          water to all of the buildings in Cambridge. This tour was led by Ed 
          Dowling, Cambridge Water Department Staff.
