Mayor Zohran Mamdani broke ground Thursday on a $185 million upgrade to the Port Richmond Wastewater Treatment Plant on Staten Island, according to a City Hall announcement. The ceremony doubled as a time capsule opening — workers pulled a sealed box from 1976, the year the plant was last rebuilt, before turning over dirt on the new work.
The project is being carried out by the city's Department of Environmental Protection, which owns and operates Port Richmond as one of fourteen wastewater plants serving New York City. The scope covers upgrades to the plant's treatment systems; the city's announcement did not break out a construction schedule or list prime contractors, and no bid or award record for the job has yet surfaced on the DEP's public solicitation channels.
For contractors, a $185 million treatment-plant upgrade at a plant this size does not get built as one lump-sum job — DEP typically splits work like this into separate contracts for structural, mechanical, electrical, and process-equipment scopes, the way it has on other plant upgrades (the city's North River plant structural work and other DEP treatment jobs currently on the board show the same pattern). Any mechanical, electrical, or structural sub with wastewater experience should be watching DEP's contract portal for the breakout.
The 1976 time capsule detail is more than color: it marks fifty years since Port Richmond's last major rebuild, which tracks with DEP's broader pattern of treating its 1970s-era plants as assets now reaching the end of their design life across the five boroughs — the same logic driving DEP's other current treatment-plant solicitations.
What to do next
Contractors working DEP's wastewater sector should set a watch on the agency's active solicitations page now, before individual trade packages for Port Richmond post — treatment-plant upgrades of this size are typically bid in stages over 12 to 24 months, and the structural and mechanical packages tend to hit the street first. Check City Record daily for a Port Richmond-specific RFP once DEP opens procurement; the groundbreaking announcement is the signal that packages are coming, not that they're available yet.
