Join us at the Allegheny County Sanitary Authority (ALCOSAN) Annual Open House on Saturday, September 17, 2024 from 9:00 a.m. to 4:00 p.m.

Rain or shine, enjoy a fun-filled day of hands-on environmental exhibits, wastewater treatment plant and laboratory tours, microbiology and watershed life demonstrations, and educational activities for all ages.

Visit the Pittsburgh Water and Sewer Authority (PWSA) booth to take part in a hands-on stormwater experiment that includes making miniature rainstorms and redesigning a model of Pittsburgh to soak up more rain! Our exhibit will also have displays and materials about our stormwater program and customer assistance programs.

The event is free and open to the public. Registration for tours is required and available on ALCOSAN's website.
