Wastewater treatment authority serving 83 Allegheny County communities
ALCOSAN operates a 59-acre wastewater treatment facility serving Pittsburgh and 82 surrounding municipalities across Allegheny County. The organization is actively scaling operations infrastructure—capital improvements, sewage system renovations, and pilot plant work dominate the project list—while grappling with data management and compliance reporting at scale (100+ industrial customers, multiple regulatory schedules). Hiring velocity is accelerating with junior operational and engineering roles leading intake, a staffing pattern consistent with facility expansion and equipment replacement cycles.

The organization operates one of the largest wastewater treatment plants in the Ohio River Valley and employs over 400 people, roughly 30 percent in salaried professional roles (engineers, managers, directors) and the remainder in union hourly positions across operations and security. Work is concentrated Monday–Friday for office and engineering staff, with rotating shifts for operations and security. Historically the agency has experienced low turnover and receives hundreds of applications annually for the 10–15 entry-level positions it typically fills each year.
