Poster for Onsite Wastewater Technologies

Presented by the National Small Flows Clearinghouse (NSFC)

This poster depicts typical uses of alternative wastewater systems in a rural community setting and shows how some onsite technologies can be clustered. Filter media systems, constructed wetlands, drip irrigation, and mound systems are just some of the technologies discussed. Known to be particularly helpful to local officials, engineers, regulators, and individual homeowners in selecting the most suitable treatment option for their situation, this poster will tell you what types of onsite wastewater treatment technologies are available in the U.S.

The technologies described are applicable to individual homes, schools, churches, restaurants, parks, and other "small-flow" situations. There is a section about common onsite systems, as well as a section about systems that can be installed in difficult site conditions, such as steep slopes, areas with nearby lakes, or other environmentally sensitive locations.
