Project Description
The South Bay Water Reclamation Plant is a component of MWWD's Clean Water Program capital improvement plan, developed to bring the agency into compliance with the Clean Water Act. The 15-mgd plant processes wastewater from the South San Diego Bay region to two levels of treatment: secondary treatment for ocean discharge and tertiary treatment for unrestricted Title 22 reuse meeting all wastewater effluent regulatory requirements. The plant is partially federally funded.
Secondary effluent not pumped to the tertiary filters for reclamation is discharged to the Pacific Ocean via the South Bay Ocean Outfall designed by Parsons.
Parsons prepared feasibility studies and drawings and specifications for the entire new wastewater treatment plant facilities including influent screening, aerated grit removal, primary sedimentation, primary effluent flow equalization, air activated sludge design for full nitrification with mixed liquor recycle anoxic zones for partial denitrification, secondary clarification, tertiary mono-media filtration, ultraviolet disinfection, potable water demineralization system, and reclaimed water pumping. Parsons designed the operations and maintenance buildings to accommodate a future 45-mgd secondary plant and a future sludge processing plant on site.
Other relevant features of this project include:
- Preparation of plans and specifications
- Wastewater treatment process design
- Building design
- Pumps and appurtenant equipment design
- Buried and exposed piping design
- Geotechnical studies
- Civil and structural design
- Odor control computer modeling and design
- Corrosion study and design
- Surge analysis
- Acoustical studies
- Scheduling and cost estimates
- Environmental permitting support
The facility includes several process-related buildings: the headworks, blower, filter, UV control, and chemical buildings, and the effluent pump station.
