Classes & Sessions
We’ve prepared a program with over 20 speakers in which industry professionals, manufacturers, various government regulatory agencies and business leaders - will challenge your knowledge of troubleshooting on-site septic systems, help to define government rules and regulations and suggest new approaches to both old and emerging problems. This year’s educational offerings include installer, manufacturer, regulatory, business, operations / monitoring and maintenance and a full OSS troubleshooting track.
These tracks, combined with familiar and new presentation formats, will allow everyone to learn something new that they can take back to their workplace.
