  1. 99% of raw sewage is water. After a greater or lesser degree of cleaning, that gets discharged to a body of water. Often the discharge point is upstream of the intake for a drinking water plant. Solids are removed by screening, skimming, and settling. The sludge from some of the processes may be sanitized, bagged, and sold as a soil amendment. The rest goes to a special landfill.

    There are some treatment plants that get rid of their liquid effluent by spray-irrigating forests. Tree growth is really boosted that way.


  2. rivers,bays,sounds and one of 3 run 15 miles out into ocean.

  3. After it is properly treated, the clear water going into rivers and streams. The sludge( black soil) is left on land or given to farms or local landowners for use in gardens.

    The water is supposed to be drinkable from the plant. The sludge pits generally will have tomatoes sprouting in them because tomato seeds are one product that doesn't digest and will grow after going through this process.

  4. Solids are separated in settling tanks, all water is filtered then discharged into the sea. Solids are usually dumped on land.

  5. Congress...  then back to us...

  6. lakes/rivers/beaches

  7. The water is normally discharged to a watercourse or the sea, smaller plants may discharge to soil and some may treat the water further for re-use were water is precious.

    Bio solids sludge and screenings are collected, compacted and dried and either incinerated, composted or taken to landfill. These are essentially the part that is removed from the water by the treatment process.

  8. Once sewage is treated it is no longer sewage. Most modern sewage treatment plants go so far as to sterilize the byproduct water before it becomes the effluent to the nearby body of water (sea, river, lake ect). The soilds from sewage treatment facilities sometimes will be serilized as well and used in fertilizers, added to composting, or landfilled if it is bad enough.

    Most of sewage is recycled though.
