The Allegheny County Sanitary Authority (ALCOSAN) has been recognized with a National Environmental Achievement Award (NEAA) for Operations and Environmental Performance, presented by the National Association of Clean Water Agencies (NACWA).
The award honors ALCOSAN’s North End Plant Expansion: ALCOSAN’s New Outfall, a major milestone within the authority’s long-term Clean Water Plan.
As highlighted in the original coverage, the new outfall project modernizes critical infrastructure and supports regional water quality improvements. The project also marked the transition from ALCOSAN’s original Ohio River outfall (in continuous service since 1959) to the new North End outfall, which was commissioned on January 16, 2025.
Project highlights (as reported)
Clean Water Plan: $2 billion long-term program
Service area: 83 municipalities served
Capacity milestone: Outfall discharge increased from 250 MGD to 295 MGD on September 4, 2025 as part of the plant capacity expansion
