Dnk,
The biosolids, or sludge, from the sewage treatment plant just down the way from the water replenishment facility is trucked out and composted...230,000 tons of it a year.
Currently, the wastewater is all sent out a pipe 4.5 miles offshore and discharged in about 200' of water. Many believe that it's the source of bacteria that often forces beach closures. The new plant will take a load off of this discharge....until population growth catches up with the whole thing again.
