Typical Wastewater Treatment Process

Most people are served by publicly-owned (city or county) water and sewer utilities. Only eleven percent of Americans receive water from private utilities. Utility services water infrastructure consists of dams, reservoirs, well fields, pumping stations, aqueducts for transporting large quantities of water over long distances and water treatment plants. Sanitation infrastructure includes sanitary sewers and combined sewers, sewage pumping stations and wastewater treatment plants.

Wastewater and sewage are transferred from pump stations to water treatment facilities for the purification of the water. These water treatment plants remove unwanted chemicals, suspended solids, biological contaminants, and gases from contaminated water. Water purification techniques include the following:

  • Filtration
  • Sedimentation
  • Distillation
  • Slow sand filters
  • Biologically active carbon
  • Flocculation and chlorination
  • Ultraviolet lighting

Water is purified primarily for human consumption. It can also be used for medical, pharmacology, chemical, and industrial applications.
