Full Answer

Water from pipes in a home or business flows from a building into the sewer. From the sewer, it moves to a sewage treatment plant where large items are removed. Next, sand and mud settles in the bottom of a treatment tank and then carted to a landfill. Oxygen goes into the remaining wastewater for help in speeding along settling and chemicals are added to remove organic matter and toxins. It then releases into a river, creek or stream.
