Hyperion Treatment Plant
The Virtual Tour Here
Sewage contains mostly water and solids. You know what those are. As you go through the tour, notice that many of the treatment processes at the plant are designed to separate solids from water.
This must take place so that when the wastewater is completely treated it is clean enough to be pumped into Santa Monica Bay. The solids have value – they are reused as an energy resource and soil amendment-fertilizer.
