Brown Acres

Brown Acres - An Intimate History of the Los Angeles Sewers by Anna Sklar

The complex and often alarming history of the Los Angeles city sewer system, complete with the relationship between headstrong politicians and the reformers who sought to “heal the bay” after a century of pollution and contamination. Brown Acres provides a unique look at the underground history of Los Angeles.

The following photos from Brown Acres are used with the author's permission.

Hundreds of workers moving sand behind the old Hyperion screening plant, circa 1937, in preparation for a new sewage treatment plant planned by then City Engineer Lloyd Aldrich. Despite a $7 million grant from the federal government, only an experimental plant to handle a small amount of sewage was started and apparently was never actually placed in operation.
