The Onsite Wastewater Short Course is a “one-stop” training/conference event for Massachusetts onsite wastewater professionals and wastewater operators (pending).

The conference serves as a forum for sharing information about onsite/decentralized wastewater issues and projects in the region and features research and case studies from across the country. Conference attendees include many of those in New England and New York State involved in onsite wastewater treatment, including state, federal, and municipal governments; private sector (i.e., installers, designers, service providers); technology manufacturers; academia; and watershed organizations. The event is offered approximately every three years, and has been coordinated and hosted by NEIWPCC since 2002 in partnership with our member states and the US EPA.

The next Northeast Onsite Wastewater Short Course will be held in 2025.
