The Town of Three Rivers is seeking engineering consulting for a predesign study of upgrades to the Montague Wastewater Treatment Plant.
- **Government buyer:** Town of Three Rivers, for the Montague Sewer and Water Utility.
- **Requested service:** One Phase 1 predesign study assessing plant condition, performance, treatment capacity, and existing and projected hydraulic and organic loads. The plant is approaching biological capacity.
- **Alternatives to evaluate:** A secondary clarifier, an aerated reactor, screening upgrades, and other relevant improvements. The study must recommend a preferred upgrade strategy and include Class D planning-level cost estimates, technical memoranda, calculations, and draft and final reports.
- **Key requirements:** Use at least a 25-year planning horizon and consider technical feasibility, operations, constructability, regulatory compliance, lifecycle and capital costs, budget constraints, climate resilience, energy efficiency, greenhouse gas impacts, and applicable federal funding requirements. Engineering work must be supervised by a Professional Engineer licensed in Prince Edward Island, and the consultant must be authorized to practice engineering there.
- **OEMs and vendors:** No OEMs or consulting vendors are named in the materials; no manufactured products, part numbers, or product quantities are specified.
- **Potential later work:** Detailed design and tendering, followed by construction-phase services, may be negotiated as separate future phases and are not part of the current Phase 1 scope.

### Description

The Town of Three Rivers is seeking proposals from qualified engineering consultants to complete a predesign study for upgrades to the Montague Wastewater Treatment Plant. The work includes reviewing existing facility conditions and performance, assessing current and projected hydraulic and organic loads, evaluating upgrade alternatives, preparing planning-level cost estimates, and recommending a preferred upgrade strategy. The study will support future detailed design, regulatory approvals, funding applications, tendering, and construction; these subsequent phases may be negotiated separately. Proposals are due by November 12, 2026, at 2:00 PM.
