A gravity sewer system conveys domestic wastewater to the District’s Wastewater Treatment Plant located on Balboa Avenue. The collection system is comprised of approximately 1.6 miles of gravity sewer pipe (mostly six inches in diameter). The District also receives wastewater from the Hearst San Simeon State Historical Monument (the State). Per our 2007 Waster Master Plan the Average Daily Flow (ADF) for the District is 77,500 gpd (gallons per day) based on flow records for 24 consecutive months from January 2004 through December 2005.
