This facility treats drinking water for a fifth of Maine’s population. The tour covers ozone treatment, UV disinfection, and water quality tests conducted in the laboratory.
Tours of this facility take two hours and are offered year-round, Monday through Friday.
Our second largest wastewater treatment facility offers the opportunity to learn about the positive impacts wastewater treatment has on the environment. The facility size allows students to view wastewater processes in a direct way.
Tours of this facility are provided Tuesday, Wednesday, and Thursday. Tours take 1.5 hours and are offered April through November (closed in the winter).
Tours at Maine’s largest wastewater treatment facility include both the facility and the laboratory, and are considered for students in higher learning institutions on a case-by-case basis. Due to staffing limitations and a simpler plant configuration, tours at our Westbrook/Gorham facility are recommended for most groups.
