Fort Dodge Correctional Facility seeks qualified vendors to furnish and install a turnkey water treatment control system designed to continuously monitor the pH level of facility supply water and automatically inject sodium hydroxide as needed to maintain desired pH balance. Project Specifications: The proposed system shall include a wall-mounted analyzer panel capable of real-time pH and temperature monitoring with a programmable controller and data logging capability. It must feature an in-line modular sensor housing, a resistance thermometer, and associated plumbing, wiring, and pressure regulation components including backflow preventer. The chemical feed system must consist of a pre-assembled, skid-mounted dual-pump sodium hydroxide injection package. This package shall include solenoid-driven diaphragm pumps (primary and backup) with pressure relief valves, backpressure valve, pulsation dampeners, calibration cylinder, and required SCH 80 PVC/EPDM piping and fittings. The skid must include a local switchover panel and require 120VAC power. All components must be factory tested, rated for continuous industrial use, and compliant with applicable safety and performance standards. The selected contractor will be responsible for delivery, installation, integration with existing water systems, and startup testing. Pricing submitted must include delivery, installation, integration with existing water systems, and startup testing.
