Huntington Beach Wastewater Treatment Facility Projects

P2-90 Trickling Filters

Project Description
The project will construct new federally mandated facilities at the Treatment Plant located on Brookhurst in Huntington Beach. The new facilities include: three trickling filters, a solids contact basin and six clarifiers to provide an additional 60 million gallons per day (MGD) of secondary treatment capacity. This project is required by the United States Environmental Protection Agency under a Federal Consent Decree requiring OCSD to meet secondary treatment standards by 2012.

Construction began in early 2007 and will last approximately 4.5 years.

Project work hours: Monday - Saturday, 8 a.m. - 5:30 p.m.

Project Facts:

Three trickling filters,150 feet in diameter and 35 feet high

Each trickling filter contains 5.3 million square feet of surface area, (enough to cover the Staples Center building almost six times)

Solids contact re-aeration basins 20 feet deep and 12,400 square feet in area (about one quarter of a football field)

Six circular clarifiers,135 feet in diameter and 23 feet deep

Each clarifier holds over 2 million gallons of water

The excavated dirt will fill a football field 42 feet high

Estimated construction cost is $200 million

The trickling filters will be covered and the foul air will be treated for odor control
