Tetrasolv Filtration Inc buyer-window signal capture

Evidence

• Hazen and Sawyer recommended adding granular activated carbon, and TriRiver says it plans a GAC treatment facility at the Siler City water plant.
• TriRiver says GAC facility design could begin before 2027, with construction potentially beginning in 2028 under a preliminary schedule.
• TriRiver estimates the Siler City GAC project at approximately $20 million and says North Carolina approved $5 million in principal-forgiveness funding.

Practical opening

“TriRiver selected GAC for a planned treatment facility at the Siler City water plant. TriRiver says design could begin before 2027, with preliminary construction in 2028. That suggests the basis of design can still be shaped before ordinary bid monitoring begins. We could offer a GAC lifecycle and vessel-basis review before design starts.”

Claim boundaryDo not claim pressure vessels are selected, design procurement is open, or the $20 million project is fully funded.

The public announcement does not state pressure-vessel geometry, carbon grade, design flow, or a formal manufacturer-input route.

Evidence

• SGWASA reported on August 10 that design reached 60% in June, with the 90% package scheduled for September 2026 and final design anticipated in December.
• CDM Smith recommends a hybrid pressure-vessel facility able to hold granular activated carbon, anion exchange resin, or Fluorosorb 200.
• The conceptual design describes pressure-vessel pairs that are 12 feet in diameter and about 27 feet tall, with hybrid underdrains and 10-inch valve-tree piping.

Practical opening

“SGWASA reached 60% design in June, with 90% due in September and final design in December. CDM Smith recommends hybrid pressure vessels that can hold GAC, anion exchange resin, or Fluorosorb 200. That suggests the flexible vessel and media basis can still be tested before the September package closes. We could offer CDM Smith a GAC and AER lifecycle review before the next package closes.”

Claim boundaryDo not claim GAC is selected, the media award is open, or AquaPRS will replace the permanent treatment train.

CDM Smith controls the specification, and named media vendors plus AquaPRS are already inside the evaluation.

Evidence

• Hanover schedules 100% design for summer-fall 2026, contractor prequalification in fall 2026, bidding in winter 2026-2027, and contract award in spring 2027.
• Hanover's 90% design shows two 12-foot-diameter lead-lag PFAS vessels suitable for GAC or IX resin and connected to a manufacturer-furnished central manifold.
• Hanover presents a $32 million PFAS upgrade covering its Beal, Broadway, and Pond Street water treatment plants, including $28.5 million in construction.

Practical opening

“Hanover schedules 100% design for summer-fall 2026, contractor prequalification in fall, bidding in winter, and award in spring 2027. Hanover's design shows two 12-foot lead-lag vessels suitable for GAC or IX, with a manufacturer-furnished manifold. That suggests a bounded approved-equal and lifecycle review may still reach Apex before contractor pricing begins. We could test vessel qualification and media lifecycle assumptions with Apex before prequalification.”

Claim boundaryDo not claim Hanover is choosing its treatment technology or that the vessel package is open; this is a specification-qualification test.

Hanover was already at 90% design in January, so the honest route is specification qualification, not treatment selection.
