Air Force-owned or -operated water production and treatment facilities will be operated with a detectable (measurable level) disinfection residual at all points of the distribution system and throughout the potable water storage tanks served by the treatment plant. This requirement varies from location to location, so the appropriate regulatory agency will need to be consulted to establish the correct level. (T-0) (Refer to

AFI 48-144 for additional guidance regarding disinfectant surveillance.)

3.2.3.2. Distribution System Inspection and Hydrant Flushing. Distribution system components such as fire hydrants and blow-off hydrants shall be inspected, preventative maintenance performed, and checked for proper operation at least semi-annually IAW

UFC 3-230-02, O&M: Water Supply Systems, and fire-flow testing/system flushing shall be conducted every five years IAW UFC 3-601-02, Operation and Maintenance:

Inspection, Testing, and Maintenance of Fire Protection Systems. The required frequency and method of flushing (routine or unidirectional) will be determined based on individual water system requirements and documented in an installation flushing plan; however in no case shall any section of water main go longer than five years between unidirectional flushings. The installation flushing plan will be coordinated with BE. (T-0) Due to

AFI32-1067 4 FEBRUARY 2015 15

corrosion and tuberculation associated with cast iron pipes, cast iron pipes may require more frequent flushing.

3.2.4. Water System Hydraulic Models (WSHM). (Follow the latest edition of AWWA

Manual M32, Computer Modeling of Water Distribution Systems) When the WSHM is used the BCE ensures installation WSHM are checked for accuracy by field flow testing. Hydrant and distribution system flow testing results shall be documented. Integrate the WSHM into the installation's GIS. For major water distribution system construction projects, the construction contract must require that the contractor update the WSHM and other associated utility management systems to reflect these construction changes or additions and help develop the most appropriate construction project design and execution. (T-1)

3.2.5. Water Treatment Logs. The Automated Civil Engineer System (ACES), electronic spreadsheets, commercial software, or other electronic formats that collect the same data as the forms in paragraphs 2.2.5.1 and 2.2.5.2 may be used in place of these Air Force forms.

0)

3.2.5.1. AF Form 1460 and AF Form 1461. Operators at every installation must prepare

AF Form 1461, Water Utility Operating Log (General). If the water requires more than minor treatment (more than chlorination), prepare AF Form 1460, Water Utility Operating

Log (Supplemental). (T-1)

3.2.5.2. Daily Well and Pumping Station Activity Records. Maintaining daily operating records for wells and pumping stations is a necessary part of water supply systems O&M. The forms in paragraph 3.2.5.1 are available for use.

3.2.5.2.1. AF Form 997, Daily Well Activity Record. Use this form to record operational information about the well. This information helps when evaluating the performance of the well and pumping system. Records showing trends such as an increase in drawdown or decreased yield help to detect existing problems and prevent future ones.

3.2.5.2.2. AF Form 998, Daily Pumping Station Activity Record–Water. Use this form to record pertinent operational information such as pumping times and rates.

Entries on this record are good performance indicators.

3.2.5.2.3. DD Forms: DD Form 2680, Military Water Well Completion Summary

Report; DD Form 2679, Piping and Casing Log; and DD Form 2678, Well Driller's Log, are prescribed by AFMAN 32-1072_IP, Water-Well Drilling Operations.

3.2.5.2.3.1. Complete and keep a file for each well, beginning with initial construction. (T-1)

3.2.5.2.3.2. Update the information after completing a repair, redeveloping a well, or conducting a performance test. (T-1)

3.2.5.2.3.3. Properly licensed personnel may be needed to construct new wells or modify existing wells IAW state and local regulations. (T-0)

3.2.5.2.3.4. Recordkeeping. The BCE verifies all required documents, records, and monitoring and sampling data are retained and for the length of time required by applicable health services departments. Some records are required to be retained for three

16 AFI32-1067 4 FEBRUARY 2015

years, others five years, and others ten years (e.g., chemical monitoring analysis, disinfection residuals if the system disinfects). Some information is kept permanently

(e.g., well siting approval letters, pump test results, groundwater withdrawal permit). The

WET application may be used to archive water system regulatory records. (T0)

3.3. Special Considerations.

3.3.1. Water Rights. The BCE will maintain permanent records on all water-related documents and data pertaining to water rights as part of asset management, specifically under the real property section (see Attachment 2). The base CES real property office will be the lead for water rights/water resources documentation. It is Air Force policy to retain water rights; if systems or services are privatized, the base shall ensure that Air Force interests in water rights/water resources are not jeopardized. (T-1) For further details concerning privatization, refer to the Air Force Utilities Privatization Playbook and consult with

AFCEC/CNU.

3.3.2. Water Vulnerability Assessments (WVA). CES personnel shall assist BE to conduct WVAs IAW AFMAN 10-246, Food and Water Protection Program, and prepare water contingency response plans (WCRP) for deficiencies identified in the WVA, WVA updates, and other required sources. (T-1)

3.3.3. Water System Lead Content. All new installations or repairs to public DW systems require the use of lead-free flux and solder, pipes, and pipe fittings as defined by the SDWA.

3.3.4. Air Force Backflow Prevention Program. Bases under U.S. jurisdiction must use the Uniform Plumbing Code (UPC) (Section 603, “Cross-Connection Control”) and UPC

Illustrated Training Manual to inspect, test, install, repair, and replace backflow prevention devices. (T-1) (Fire protection systems are exempt from this requirement. See paragraph

3.3.4.6 for fire protection systems requirements.) When the backflow requirements of this

AFI, the UPC, and the International Plumbing Code (IPC) conflict, comply first with this

AFI, second with the UPC, and third with the IPC, all in accordance with state/local regulations. If no state or local training/certification is specified, certificated training from any state/local or Air Force approve certificated program is required at a minimum. Specific backflow requirements are as follows:

3.3.4.1. Design of Equipment. BCE personnel must first consider designing a solution to eliminate the potential for a cross-connection. (T-0)

3.3.4.2. Device Accessibility. New and existing backflow devices will be planned for and installed to be readily accessible within 1 to 5 feet (0.3 to 1.5 meters) above the floor or grade, at least 1 foot (0.3 meter) from the back wall and have at least 1 foot (0.3 meter) clearance above the device, and documented on AF Form 845, Cross-Connection

Information or state mandated forms. Backflow devices must be installed with appropriate clearances and in accordance with the manufacturer’s installation instructions. (T-0)
