STATEMENT OF WORK

DETROIT STERILE PROCESSING SERVICE (SPS)

CRITICAL WATER TREATMENT SYSTEM

1. GENERAL INFORMATION

The primary objective of this contract is to provide Sterile Processing Service (SPS) with an incoming water quality system that meets AAMI TIR 34 and SPS equipment manufacturer’s specifications for microbial and chemical quality. The SPS water purification system shall provide reliable high purity water that reduces pitting and corrosion on instruments, reduces microbial fouling and scaling, and improves cleaning quality and efficiency at the John D. Dingell VA Medical Center, Detroit, MI 48201.

2. SCOPE of WORK:

The water treatment equipment shall be effective, reliable, economical, and consist of three elements: pretreatment, a principal water treatment process, and distribution.

a) Pretreatment shall consist of sediment filter, carbon filtration, and water softening for protection of the principal water treatment components.

b) Principal treatment process shall consist of reverse osmosis (RO), deionization (DI), water quality sensors, bacteria filter, distillation, or a combination of these processes.

c) Distribution system shall continuously disinfect the critical water by means of distribution pump, ultraviolet (UV) light, and endotoxin filtration. The distribution system shall provide sample ports for testing critical water at the tank loop return, and the endotoxin filter loop out. Storage tank for purified critical water shall drain from the lowest point of the base. The storage tank shall have a tight-fitting lid, be easily disinfected, and be vented through a hydrophobic 0.2 μm air filter that is accessible for regular scheduled maintenance.

For minimization of biofilm formation, a minimum velocity of 3 feet per second (ft/sec) is required in the distal portion of the loop under conditions of peak demand. A multistage centrifugal pump made of inert materials is required to distribute the purified water and aid in effective disinfection.

The critical water treatment system shall be able to be installed in a way that provides easy access to all components of the system, including all meters, gauges, and sampling ports used for monitoring system performance, and is capable of supporting future expansion.

All connections shall be capable of being solvent welded. Threaded joints are not allowed, as they contain spaces in which water could collect and stagnate, thereby increasing the potential for bacterial growth.

Alarms, such as those associated with deionizer exhaustion or low water levels in a storage tank, should be configured to sound both in the water treatment area, in the occupied SPS space, and the VAMC central alarm monitoring location, such as the boiler plant.

3. CONFORMANCE STANDARDS:

All services provided under this contract must be performed in conformance with the Federal regulations, National Fire Protection Agency (NFPA), Occupational Safety and Health Administration (OSHA), Manufacture standards and specifications, and the John D. Dingell VA Medical Center policies and requirements.

4. HOURS OF WORK:

Regular working hours are Monday through Friday, 7:00 a.m. EST to 3:30 p.m. EST. Any additional services beyond this window may require additional approvals from the COR/CO.
