Attachment 1 - Statement of Work REV2

1 PURPOSE. This Statement of Work (SOW) outlines the cross-connection survey to conduct a comprehensive evaluation of Fairchild AFB’s (FAFB) water system to protect potable water from potential contamination. The survey aims to ensure compliance with federal, state, and local regulations and industry best practices. The primary objectives of this SOW are to:

1.1 Identify actual or potential cross-connections.

1.2 Evaluate adequacy of protection of existing backflow prevention devices (BFDs).

1.3 Identify deficiencies related to cross-connections and associated BFDs.

1.4 Provide corrective action recommendations to protect the potable water system.

2 APPLICABLE CODES AND STANDARDS. The survey shall, at a minimum, comply with the following requirements, standards, and codes:

2.1 Department of the Air Force Manual (DAFMAN) 32-1067, Water and Fuel Systems:

Governs operation, maintenance, and protection of Air Force potable water systems.

2.2 Air Force Instruction (AFI) 48-144, Drinking Water Surveillance Program: Ensures potable water safety and quality.

2.3 Unified Facilities Criteria (UFC) 3-230-01, Water Storage, Distribution, and

Transmission

2.4 UFC 3-420-01, Plumbing Systems

2.5 Washington Administrative Code (WAC) Title 246-290-490, Cross-Connection

Control Requirements: Provides state-specific cross-connection control guidance.

2.6 Uniform Plumbing Code (UPC): Industry standards for plumbing systems, including cross-connection control.

2.7 American Water Works Association (AWWA) M14 Manual, Recommended Practice for Backflow Prevention and Cross-Connection Control: Sets industry standards for surveying and protecting water systems.

2.8 University of Southern California (USC) Manual of Cross-Connection Control:

Recognized reference for backflow prevention device standards.

2.9 Washington State Department of Health (DoH) Guidance: Ensures compliance with state regulations for water system safety.

3 SCOPE OF WORK. The contractor shall, via physical observation and industry standard practices, conduct a comprehensive survey of the entirety of the premise (transmission and distribution lines) and in-premise protection, for each of Fairchild AFB’s water systems, including the water systems at geographically separated units (GSUs). Include all vaults, Air Relief Valves (ARVs), insertion-extraction points, hose bibs (including RV sites, parks, etc), irrigation connections, etc. along the lines/system. Contractor will not be expected to dig to locate devices; FAFB will provide maps with known GIS coordinates of BFDs if available (reference Appendices B1, B2, and D).

3.1 System Details: The following are not to be assumed as 100% accurate but rather only for approximation purposes for this SOW. The water system includes roughly:

The following details are provided for bidding purposes. The contractor is responsible for a 100% physical inspection of the water systems as described. The provided

FA462026QA210

appendices (B1, B2, C1, C2, D) list known components but are not considered all-inclusive. The system includes approximately:

3.1.1 500 known backflow preventers (reference Appendix C1), 3.1.1 490,000 linear feet of piping (encompassing distribution, transmission, and service lines).

3.1.2 300+ buildings associated with Backflow Devices or potentially connected to the water systems in general, including GSUs (totaling 4.4M sqft, averaging 14.4k sqft per building) (reference Appendices C1 and C2). 3.1.2 500 connections requiring survey, of which approximately 305 are within facilities. The remainder are connections outside of facilities (e.g., irrigation systems, yard hydrants, etc.).

3.1.3 390k+ linear feet of Main Line, which includes 60k+ linear feet of Main Transmission Line. (Appendix B1) 3.1.3 2 Medical and Dental clinic facilities (with 4 BFDs per the ASR)

3.1.4 100k+ linear feet of Service Line (these numbers include both active and abandoned line lengths). (Appendix B1)

3.1.5 2 Medical and Dental clinic facilities (with 4 BFDs per the ASR) (App. B1).

3.2 The survey shall address the following areas:

3.2.1 Premise and In-Premise Protection

3.2.1.1 Inspect external and internal water system components to identify cross-connections.

3.2.1.2 Evaluate adequacy of backflow prevention devices in use for compliance with applicable codes. (Physical evaluation of devices’ function is not necessary.)

3.2.2 Irrigation Systems

3.2.2.1 Inspect irrigation systems for cross-connections.

3.2.2.2 Evaluate the adequacy of backflow prevention measures for irrigation systems. (Physical evaluation of devices’ function is not necessary.)

3.2.2.3 Note 1: Some facilities may have irrigation BFDs within the building.

3.2.2.4 Note 2: FAFB assumes there are upward of 10% additional connections unaccounted for on the irrigation system.

3.2.3 Fire Protection Systems

3.2.3.1 Inspect fire protection systems for potential cross-connections.

3.2.3.2 Assess backflow prevention devices associated with these systems for proper selection and function. (Physical evaluation of devices’ function is not necessary.)

3.2.3.3 For non-potable fire suppression systems, stop evaluation at the cross-connection device.

3.2.4 Geographically Separated Units (GSUs) encompass 5 separate water systems (Ft. Wright Wells & Cemetery and Geiger Reservoir make up 1 water system):

3.2.4.1 Ft. Wright Wells and Cemetery (FAFB water system)

3.2.4.2 Geiger Reservoir (FAFB water system with backup intertie to City of Spokane)

3.2.4.3 White Bluff (independent water system)

FA462026QA210

3.2.4.4 Ruby Creek (independent water system)

3.2.4.5 Tacoma Creek (independent water system)

3.2.4.6 Clear Lake Recreation Area (independent water system)

3.2.4.7 The approximate one-way travel distances from Fairchild AFB to the GUS’s are as follows: Ft. Wright Wells & Cemetery:10 Miles;

Geiger Reservoir: 7 Miles; White Bluff: 9miles; Ruby Creek: 90 miles; Tacoma Creek: 74 miles; Clear Lake recreation Center: 17 miles.

3.3 The survey shall not address Balfour Beatty-contracted housing units; survey stops at the last BFD before the distribution line solely supplies the housing communities.

4 SURVEY REQUIREMENTS. The contractor shall:

4.1 Conduct the survey between 01 July 2026 and 30 September 2026.

4.2 Physical observation and assessment of status of device protection (i.e. ARVs) along the entire route of the Main Transmission Line from the source wells at Ft. Wright to Geiger Reservoir to FAFB is to be performed between 01 Jul 2026 and 30 Sep 2026 to facilitate easier observation of potential leak or cross-connection sources. To reiterate, the entire route of this Main Transmission Line is to be physically observed for potential cross-connection risks.

4.3 Conduct a thorough on-site inspection of the water system for cross-connection prevention, including service connections, internal plumbing, and water-using equipment. Unless otherwise specifically directed by the government, the entirety of the system is to be assessed.
