Getting to Know Windham
Windham is the gateway to the Sebago Lakes Region, straddling the Route 302 corridor between Portland and the lake country. Sebago Lake itself supplies drinking water to most of Greater Portland, and Windham's shoreline neighborhoods on Sebago, Little Sebago, and Highland Lake are full of camps that have been converted into year-round homes.
Those conversions are the heart of septic work in Windham. A camp system sized for summer weekends in the 1970s can't handle a family living there twelve months a year, and shoreland zoning adds strict setback and design requirements for any system near the water. Because this watershed feeds the region's drinking water supply, a properly functioning septic system here isn't just a property issue — it's a public one.
We've replaced and upgraded lakeside systems across Windham for over three decades, and we know how to navigate shoreland permitting, tight camp-road access, and small lots without cutting corners. If you're converting a seasonal property or buying one, we can tell you exactly what the existing system can and can't support.
