Tours of the plant can be arranged by calling the plant at (717) 292-4911, ext. 21. Please call at least 2 weeks ahead to make sure that safe and proper arrangements can be made to facilitate your group. For safety sake, tours are only given during daylight hours and in dry weather. We welcome tours from school groups, scouts, and other organizations. The plant usually has an open house in September with tours and demonstrations. Check the WWTP part of the website for more information.
