Submarine Outfall 

The existing submarine outfall is a 24-inch diameter, concrete encased pipe with 10 diffuser ports extending approximately 4.5 feet above the top of the pipe. The risers are 8-inch diameter with a reducing 90-degree elbow at the top. The discharge is through a 3-inch diameter flanged pipe end. Each port has a rubber “duckbill” type valve to prevent debris from entering the outfall pipe during periods of low flow.

The existing point of discharge is just southerly of the mouth of the Carmel River at North 36 degrees, 32 minutes, 02 seconds of latitude, West 121 degrees, 55 minutes, 40 seconds of longitude at a depth of approximately 36 feet, 600 feet off-shore.
