Hi everyone
I am working on a project to stabilize an ocean outfall pipe ( 72 inch Dia.)constructed in 1980 and has cathodic protection system. A study has been completed by Pure Technologies to monitor the condition of the pre-stressed outfall pipe (section of the pipe about 2.5 miles under water) The recent results indicated that the section of the pipe in the water has a high number of wire breaks.
The outfall can not be shut dawn because there is no storage capacity in the waste-water treatment plant and temporary pipe(bypass)is not going to be allowed be environmental department besides the heavy boats traffic at the bay, therefore the slip-lining solution to stabilize the pipe is not considered. The pipe is buried about two feet below the bed level of the bay. The recommendation based on the high rate of wire breaking (717 wire breaks in 130 days) is to replace the outfall. We are trying to stabilize the pipe for the time being and until a new outfall is constructed. Any ideas about other restoration options!
Thank You
