Small Wastewater Systems
Design, Construction, and Operation
Course Outline
The Clean Water Act (CWA) of 1977
made it unlawful to discharge any pollutant from a point source into navigable waters, unless a permit was obtained.
EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls discharges.
Industrial, municipal, and other facilities must obtain NPDES permits if their discharges go directly to surface waters.
This online course provides guidance and criteria for the design and selection of small-scale wastewater
treatment facilities. Information necessary to select, size, and design such
wastewater treatment unit processes, and guidance to generally available and
accepted references including detailed design examples for such information
are presented.
This course includes a multiple-choice quiz at the end, which is designed to
enhance the understanding of course materials.
