have taken place in the region over the last 50 years. Pittsburgh, once known as the "smoky city", has established itself as a center for high technology. Another remarkable change is the transformation of area rivers and streams from open sewers to waterways safe for recreation and commerce. The Allegheny County Sanitary Authority continues to operate on the same premise it was founded on in 1946 - to provide environmentally sound wastewater collection and treatment. And while ALCOSAN was originally designed to address water pollution, its environmental scope has grown to include two other precious commodities - our land and our air.

ALCOSAN's forefathers lead by Founder, former Executive Director and Chairman of the Board, John F. Laboon, tackled the issue of stream abatement with years of engineering, laboratory and financial studies. But perhaps the largest part of ALCOSAN's success is the dedication of its employees to the plant's mission throughout the years.

ALCOSAN's employees take pride in the accomplishments that have taken place during the past 50 years and ALCOSAN's future holds great promise as well. Utilization of advanced wastewater technology will carry the Pittsburgh region into the 21st century.

As a result, Pittsburgh and its neighboring communities will continue to benefit from strong economic development, recreational activities and a thriving aquatic and plant life environment along the three rivers.
