Abstract:

The City of Los Angeles' 1.1 billion U.S. Hyperion Full Secondary Project has triumphed over 14 years of design and construction challenges in the world’s sixth largest metropolitan area, earning the designation by the American Public Works Association as "one of the great environmental achievements of the 20th Century". This comprehensive wastewater treatment upgrade provides an average design capacity of up to 1,700,000 m3/d (450 mgd).

As the Project moved from concept to reality, many technical and institutional challenges were successfully resolved:



Meeting schedule requirements of a negotiated Consent Decree to reach full secondary treatment standards for the first time in nearly half a century.


Keeping facilities operational 24 hours a day throughout an 11-year construction period.


Implementing state-of-the-art treatment technologies.


Significantly increasing primary, secondary, and biosolids handling capacity on the existing site.


Being a good neighbor to the surrounding community, including residents whose homes overlook the project site.
