 International Wastewater Treatment Plant
This facility has operated in violation of its discharge permit since 1998, and is now the subject of litigation (State of California vs. federal government)

Impacts of the Ocean Outfall
Results of independent ocean monitoring tests conducted over the outfall connected to the IWTP.

San Diego Clean Water Alliance:
The Alliance was created in 1994 to protect San Diego's ocean water quality, and is now called "the San Diego Bay Council." Members include the Sierra Club (San Diego Chapter), Audubon Society, Surfrider Foundation, San Diego Baykeeper, and Environmental Health Organization. 
Over the years these organizations have informed the public about water quality threats, monitored the environmental impact studies for the construction and operation of sewage treatment plants, pipelines and other infrastructure, and worked with volunteers, elected officials and public agencies to keep our beaches and bays clean.

International Wastewater Treatment Plant

Background on the construction and operation of the IWTP that is located in San Diego and treats sewage from Tijuana, Mexico. Unfortunately, it accounts for nearly 50% of sewage permit violations in this region because it lacks secondary-level treatment facilities.

Impacts of the IWTP's Ocean Outfall
The outfall is connected to the IWTP, and discharges partially treated sewage into 95 feet of water only a few miles from shore near the city of Imperial Beach.

The effluent causes high bacteria levels, odors and discoloration on the ocean surface when the sea water temperature cools during the winter months. A new program, using Coastal Ocean Dynamics Radar (CODAR) will begin Spring 2002, to track the migration of this sewage plume over the ocean surface. This program is being jointly funded by the City of Imperial Beach and the State of California's Clean Beaches Initiative. Research is being coordinated by Scripps Institution of Oceanography in La Jolla, California. First results are anticipated Summer 2002.
