Portland Water District and the Town of Windham marked the opening of the new North Windham Wastewater Treatment Facility on 8 October 2026 with a ribbon-cutting ceremony attended by state and federal officials. The plant pairs biological treatment with fine membrane filtration and disperses the treated water underground beneath new athletic fields at a local school. Officials expect the system to eventually replace more than 100 septic systems and keep roughly 22,000 pounds of nitrogen and 3,000 pounds of phosphorus out of the local aquifer each year.
