# USACE Rehabilitates Tracy Wastewater Plant

The U.S. Army Corps of Engineers Sacramento District is managing a **$9.7 million** rehabilitation of the World War II-era wastewater treatment plant at Defense Logistics Agency Distribution San Joaquin in Tracy, California. G.S.E. Construction Company Inc. received the construction contract in July 2025, and work is ongoing. Rehabilitation has uncovered additional deficiencies that may require attention; the project is not a new solicitation.

- The work includes mechanical equipment replacement, structural repairs, electrical upgrades, and pump and piping replacement to keep the facility operational.
- Procurement teams should distinguish this active construction contract from a new competition; newly identified deficiencies may affect project scope or prompt additional requirements.
- Contractors with wastewater-treatment, mechanical, electrical, and structural rehabilitation capabilities can use the project as an indicator of infrastructure needs at aging logistics facilities, without assuming follow-on work has been announced.
