Yonkers Sewage Treatment Plant — 1973 sludge-thickening / process work

EPA records specifically cite centrifugal thickening at Yonkers in 1973.

Likely concrete-block/brick process-building walls, equipment-room partitions, shafts and localized masonry around sludge/process structures; not the primary reinforced-concrete tanks themselves.

This scope is recorded as strong, not documented. It is a disciplined reading of the building and the trade practice of the period, not a contract-level record of Kelly’s work.

The construction team for this job has not yet been established.
