Wastewater

Onsite wastewater treatment systems refer to any system used to treat and dispose of/recycle wastewater from homes, businesses, industrial facilities, and sometimes entire communities. Environmental health professionals working at local or state health departments evaluate potential sites for onsite systems, issue permits or licenses for technicians, conduct inspections, and enforce local regulations.

  • Septic systems usually serve up to 20 people, oftentimes individual households or small businesses, and include a septic tank and soil absorption field.
  • The frequency of septic systems varies by region, ranging from 10% to over 50% of homes in some states.
  • Larger, more complex systems, use advanced treatment units which treat and discharge to surface waters or the soil.
  • When used properly, onsite systems protect public health and the environment by reducing disease transmission and removing pollution from surface and groundwater.
  • Individual onsite systems are typically regulated by states, tribes and local governments, while large capacity septic systems are regulated by the EPA.

National Onsite Wastewater Recycling Association Webinar Series

Hosted in partnership with the (NOWRA).

Part 1 | Onsite Wastewater Treatment: What is it and where can I go for information?

This webinar provides an overview of sewage disposal systems, also known as onsite wastewater treatment systems, and where they can go for additional information. The webinar discussed the basic types of onsite wastewater treatment and dispersal methods, showcased a new free homeowner鈥檚 education tool, and presented additional resources and training opportunities for environmental health professionals who need to learn more about onsite wastewater. A discussion of who NOWRA is, along with a preview of part two of the webinar series, what to look for as a food inspector, were also discussed.

Part 2 | Sewage Disposal: A priority item you may be overlooking

Sewage disposal is a Priority Item discussed in Chapter 5 of the Food Code and found under the Physical Facilities section of the Food Establishment Inspection Report. The code itself calls for an approved sewage disposal system in 5-403.11 but is very vague on what to look for to verify the system is approved. This webinar takes a closer look at individual sewage disposal systems that serve many rural retail food and food service facilities. Additional resources and training opportunities for environmental health professionals are also discussed.
