NODP Phase I

The National Onsite Demonstration Program's (NODP) Phase I provided small communities in six U.S. states seed money for the design, installation, and monitoring of alternative wastewater systems.  Each community, representing diverse geographic regions, has both unique, yet some common wastewater-related problems.

The six Phase I demonstration sites and some of the environmental concerns that were addressed include:

  • Paradise, California, where stringent state standards for groundwater protection require removing nitrates and pathogens through soil absorption.
  • Gloucester, Massachusetts, which has coastal pollution and whose site restrictions include a high groundwater table and shallow, glacial soils.
  • Waquoit Bay, Massachusetts, an area with coastal pollution and highly permeable soils.
  • Anne Arundel County, Maryland, which needs to control and prevent pollution of the Chesapeake Bay.
  • Benzie County, Michigan, which has restrictions caused by numerous lakes, small lots, sandy soils, and seasonal fluctuations in population.
  • And Monongalia County, West Virginia, with difficult terrain and shallow, impermeable soils.


A total of 26 proven and innovative systems were installed, including constructed wetlands, drip irrigation systems, biofilters, and recirculating sand filters.

On completion of the project, a detailed summary report of NODP I was published, giving details about each project and a summary of the monitoring results obtained. A technical file was also compiled containing details of the construction and monitoring of the various projects.
