Is drinking water chlorination required?

Chlorination or other continuous disinfection (disinfection that protects from the treatment plant to the consumer’s tap) is required for public water systems that:

  • Use surface water, such as rivers, lakes, and streams, as their source; 
  • Have treatment processes that expose the water to outside or open air; or
  • Add treatment chemicals for corrosion control; these chemicals can feed microorganisms and cause them to grow 

Disinfection is recommended but not required for other community public water systems
