So what was in the water in Lybia?Depending on the stainless steel type you use it can be open to chloride attack at the water line .
it is possible to overcome this by using Duplex or even super Duplex grade of stainless.
In Libya when Gadaffi wanted to Irrigate the desert using sour well water they sank a pipe in mild steel down and it had rotted within 2months they then tried 316L stainless and that didn't last that much longer, we did a lot of work with a British company and ended up doing test pieces in super Duplex for them to do a hydraulic test and a G48 test, the pipe was 8" dia, with a wall of 5/16" the bolting flanges were 2" thick cast in super Duplex all TIG welded.
The best laugh was that when we had to talk to the engineering company about the project their design engineer had specified 316 stainless bolts and we all knew what had happened to the 316L pipe.
