The residents, businesses, and tourists to the City and Borough of Juneau are serviced by 7,100 sewer connections via a network of roughly 140 miles of pipes and 45 lift stations known as the Collections System. The sewer collection lines convey the flow to one of the three treatment plants (Juneau-Douglas WWTP, Mendenhall WWTP, or Auke Bay WWTP) located throughout CBJ which processes nearly 3.3 million gallons per day (MGD) or roughly 1.2 billion gallons of water annually.
