Rochester Water Reclamation Plant

AP is collaborating with the Rochester Water Reclamation Plant to execute critical improvements aimed at modernizing its operations and increasing efficiency. Serving approximately 120,000 residents with a rated annual capacity of 16 MGD, the facility currently operates two treatment streams: one using high-purity oxygen (HPO) and the other conventional aeration.

This project is addressing two key challenges. First, AP is replacing the outdated HPO equipment by converting both streams to conventional aeration, streamlining operations and unifying the treatment process. Second, combining the two streams is simplifying sludge processing, creating a single, more efficient solids handling system.

Unlike traditional wastewater facility expansions, this project involves minimal new concrete tank construction but requires extensive civil yard piping to integrate and connect the existing treatment tanks. These upgrades are optimizing the plant’s infrastructure and improving operational flexibility, highlighting AP’s capability to provide impactful solutions in active facilities.

This project is anticipated to be completed in December 2026.
