New Hamburg WWTP - Aeration Diffuser & Header Replacement
The Region of Waterloo is seeking bids under Request for Tender T2026-211 for rehabilitation and upgrade of the aerobic digester basin aeration systems at the New Hamburg WWTP. The work includes cleaning the existing basins, demolishing existing aeration equipment, modifying concrete supports, and installing a new coarse-bubble diffuser system with twin air headers. It also includes process-air piping and valving changes, a valve chamber, and overflow piping between basins; the official record classifies it as construction procurement, not a grant program.
