OCSD releases treated water into the ocean through a 120-inch diameter offshore pipeline that extends five miles from shore to the discharge point approximately 200 feet below the ocean surface. An emergency standby 78-inch diameter pipeline stretches one mile from shore. The one-mile-long diffuser section of our five-mile ocean pipeline contains 503 portholes through which treated wastewater is slowly released. An abundance of marine life has taken up residence along both pipelines.

Ocean Monitoring

OCSD generates an average of 699 tons per day or 255,000 tons per year of biosolids. Biosolids are beneficially reused through land application, composting and fuel production.

OCSD generates an average of 11,000 kilowatts of energy from burning natural gas and methane gas (biogas), which is a byproduct of the wastewater treatment process. On an annual average basis, the treatment plants use 14,500 kilowatts.

Our award-winning ocean monitoring program monitors and evaluates water quality, sediment quality and sea life from Seal Beach to Corona Del Mar.
