Effluent from failing septic systems is a major water quality concern in the Lake Winnipesaukee watershed, as the majority of properties around Lake Winnipesaukee rely on onsite wastewater disposal systems (septic systems).

Compounding the issue is the fact that many properties are seasonal, second homes or rental properties. Many property owners may not know that they have a septic system, where it’s located or when it was installed. To help people better understand the functioning of septic systems and how to care and maintain this critical component of their home, LWA has sponsored several Septic Sense Seminars around the Winnipesaukee watershed.
