PERFORMANCE WORK STATEMENT

SCOPE

Puget Sound Naval Shipyard & Intermediate Maintenance Facility San Diego Detachment (DMF) located on Naval Air Station North Island (NASNI), has a need for leased portable demineralizer (DI) water systems. DMF requires one DI system at all times, fully operational and ready for use, with a second DI system available within 24-hours’ notice.

The number of DI water systems needed during a one-year period of performance fluctuates depending on the amount of work performed at the detachment.

Regeneration is the process or maintenance on the Demineralizer system that the company performs to exhaust its resin to restore it to proper ionic form to process water again. Previous contracts for DI systems have been allotted to 30 regenerations per contract calendar year.

SPECIFICATIONS FOR DEMINERALIZED WATER CONTRACT NASNI

1. This Specification describes the minimum requirements for the lease of demineralizer equipment to remove particulates, inorganic dissolved solids and chloroform from City of San Diego water at Naval Air Station North Island (NASNI). This includes vendor related services necessary to meet Puget Sound Naval Shipyard (PSNS) demineralized water needs during the five year schedule.

1.1. Where “demineralizer” or “demineralization” is specified, it shall be construed to allow the use of reverse osmosis, electro-demineralization or other appropriate continuous water treatment method as all or part of the water treatment process.

1.2. Estimated gallons processed is 40,000 gallons per week, but may vary + /- 30% depending on operational demands. Usage estimates may be revised yearly to account for changing customer workload conditions.

1.3. The contractor shall provide and maintain the required leased equipment listed in paragraphs 1 through 1.2 to include maintenance and regeneration necessary to maintain equipment in a fully operational condition. The demineralizers and filters shall be leak tested and certified for minimal leakage up to and including the inlet and outlet connections prior to delivery. The demineralizer and filter media shall be delivered in a fully regenerated wetted and flushed condition suitable for immediate use. Minimal leakage is defined in Quality Assurance Surveillance Plan.

2. Description of Demineralized Water Systems

2.1. Each leased demineralizer system shall be a self-contained commercial trailer, that is capable of producing at least 100,000 gallons of demineralized water, based off of the raw water quality specified in Table 1, at a flow rate up to 75 GPM, meeting the specification of Table II, without flushing by personnel at NASNI and additional servicing by the contractor when the following utilities are connected:

A. Electrical power (110-120 volt, 60 hertz, 1 phase, or 480 volt, 60 hertz, 3 phase) for operation of conductivity meter, alarms, automatic valves, pumps, etc.

B. Fresh water meeting the specification of Table I to be processed.

C. (If required) sewer drain hose directed to NASNI gravity/pressure sewer system. Maximum sewer backpressure is estimated to vary between 0 and 30 psig.

2.1.1. Influent fresh water is supplied via City of San Diego Water Department. Table I shows expected maximum mineral content of this water supply. The supply is a combination of well water and surface water, and may change from one to the other during the course of a year. Temperature of the supply may vary from approximately 56 oF in January to about 78 oF in August. Naval Air Station North Island or Puget Sound Naval Shipyard will provide samples to vendors for independent testing prior to submittal of offer if requested from Contract Specialist.
