This is a record document set containing engineering drawings for a reverse osmosis (RO) water treatment system replacement project at ICVA Health Care System. The document includes one-line flow diagrams prepared by Fourfront Design, Inc., dated January 3, 2023, with record document updates dated February 1, 2024. The project is identified as drawing number M-002 and is part of project 636A8-22-004 managed by the Office of Construction and Facilities Management.

The RO system design encompasses multiple treatment stages and components including particulate filters, UV disinfection units, carbon filters, endotoxin filters, deionizer equipment, water softener with bypass capabilities, storage tanks, and associated piping and valve systems. The system utilizes Schedule 80 PVC piping for the RO distribution lines, stainless steel shut-off valves (SOV) throughout, check valves, blending valves, pressure gauges, thermometers, and flow meters (Hydronix 0-100 GPM and Blue-White 0-80 GPM visual flow meters). The design includes provisions for UV disinfection, sanitary sample ports, and ozone injection capability. Installation requirements specify that contractors must add unions on both sides of each equipment unit for isolation and removal purposes. The construction documents indicate this is a fully sprinklered installation at 100 percent completion status, representing a complete replacement of the facility's existing RO systems.
