Request for Proposals (RFP) 2021 City of Kenai WasteWater Treatment Plant (WWTP) Sludge Press Replacement Equipment Selection

The City of Kenai is seeking a qualified vendor to supply, deliver, and commission a new screw‑press dewatering system (including polymer dosing and flocculation equipment) to replace its 40‑year‑old belt press at the municipal wastewater treatment plant. The contract covers equipment fabrication, performance testing (pilot runs), warranty, and control‑panel integration, while installation will be handled under a separate construction bid. Vendors must meet specific performance criteria (e.g., 240 lb/h dry‑solids capacity, ≥ 92 % solids capture, ≤ 89 dBA noise) and provide detailed technical data, cost breakdown, and a 12‑month full‑parts‑and‑labor warranty. The procurement process includes a pre‑proposal Zoom meeting, a sludge‑sample request, and a firm submission deadline of May 25 2021. • Supply and deliver a complete screw‑press unit with control panel (NEMA 4X, Allen‑Bradley PLC/PanelView, VFDs) meeting defined capacity and noise limits. • Provide polymer dosing recommendations (cost excluded) and specify wash‑water booster pump requirements (cost excluded). • Conduct on‑site pilot testing (minimum three 7‑hour runs) and furnish warranty, warranty documentation, and performance bond. • Submit three hard‑copy technical proposals and one sealed cost proposal (or equivalent electronic PDFs) by the stated deadline.
