Water Treatment Industry In USA

Drinking water supplies in the United States are among the safest in the world. However, even in the U.S., drinking water sources can become contaminated, causing sickness and disease from waterborne germs, such asCryptosporidium, E.coli, Hepatitis A,Giardia intestinalis, and other pathogens.


Drinking water supplies in the United States are among the safest in the world. However, even in the U.S., drinking water sources can become contaminated, causing sickness and disease from waterborne germs, such asCryptosporidiumE.coli, Hepatitis A,Giardia intestinalis, and other pathogens.

Drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents. Public drinking water systems use various methods of water treatment to provide safe drinking water for their communities. Today, the most common steps in water treatment used by community water systems (mainly surface water treatment) include:

Coagulation and Flocculation

Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc.


During sedimentation, floc settles to the bottom of the water supply, due to its weight. This settling process is called sedimentation.


Once the floc has settled to the bottom of the water supply, the clear water on top will pass through filters of varying compositions (sand, gravel, and charcoal) and pore sizes, in order to remove dissolved particles, such as dust, parasites, bacteria, viruses, and chemicals.


After the water has been filtered, a disinfectant (for example, chlorine, chloramine) may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses.

Water may be treated differently in different communities depending on the quality of the water that enters the treatment plant. Typically, surface water requires more treatment and filtration than ground water because lakes, rivers, and streams contain more sediment and pollutants and are more likely to be contaminated than ground water.

Demand for water treatment equipment in the US is forecast to grow 5.9 percent per year to $13.0 billion in 2017.
Some water supplies may also contain disinfections by-products, inorganic chemicals, organic chemicals, and radionuclides. Specialized methods for controlling formation or removing them can also be part of water treatment.

Some common, market opportunities exist across geographic boundaries to one degree or another. The states and nations need solutions to problems of:

  • Insufficient water quantity and/or quality
  • Available water resources not being where demand for water is located
  • Wastewater treatment expansions and upgrades
  • Energy costs playing an increasingly important role in water decisions
  • Water policies not keeping up with the changing water needs
  • Resistance to change, be it in policies or practices
  • Insufficient monetary resources allocated to addressing water needs

Water Quality Regulations in the United States

TheEnvironmental Protection Agency (EPA), under the requirements of theSafe Drinking Water Act (SDWA), regulates drinking water in the United States. The EPA additionally regulates wastewater, but under the requirements of the Clean Water Act (CWA). Storm water and discharges into surface water are also regulated under the CWA.

The SDWA sets maximum contaminant levels (MCLs) and treatment techniques (TTs) that drinking water must meet to be considered safe for consumption. The list includes microorganisms, disinfectants and disinfection by-products, inorganic chemicals, organic chemicals, and radionuclides.
