About this file
This document is Appendix E of the NSA Annapolis USNA Valve Exercise Standard Operating Procedures, which outlines the mandatory procedures for conducting valve exercises and inspections at the facility.
The procedures establish nine primary operational sections: initiation using the NSA Annapolis USNA Valve Exercise Plan Report and daily schedule maps; public announcements to building managers, base security, and the local fire department; equipment preparation including valve keys, wrenches, hydraulic machines, traffic control devices, and fifty copies of valve exercise forms; traffic control protocols; in-service valve exercise procedures; abandoned valve inspection procedures; cleanup requirements; and documentation submission. For in-service valves (indicated by green circles on schedule maps), personnel must locate, inspect, establish traffic control, remove covers, record initial information, exercise valves through multiple close/open cycles while monitoring torque thresholds and counting turns, check for external leakage, record measurements including depth and size calculations, and complete valve exercise forms. For abandoned valves (orange circles), only visual inspections are required to check for leakage, with marking as abandoned if not previously designated. All valve changes must be submitted to UEM and the GIS department for distribution system updates, and completed forms must be scanned or filed. The procedures emphasize hazard evaluation at each location, traffic safety compliance, and comprehensive documentation to ensure systematic maintenance and tracking of the water system's valve infrastructure.

APPENDIX E
Valve Exercise Standard Operating Procedures
Appendix E
Valve Exercise Standard Operating Procedure
1. Start Valve Exercise
1.1 Open the NSA Annapolis USNA Valve Exercise Plan Report
1.2 Review Appendix D schedule map for each day
1.2.1 Exercise in-service valves (green circles) on the schedule map for that day by following the procedure in section 6.
2. 1.2.2 Physically inspect the abandoned valves (orange circles) on the schedule map for that day by following the procedure in section 7.
3. Send public announcements
3.1 Send valve exercise announcement to building managers
3.2 Coordinate valve exercise schedule with base security
3.3 Inform local fire department for potential fire alarm triggers when performing service valve exercises
4. Prepare needed equipment
4.1 Two valve keys
4.2 Hydrant wrench
4.3 Valve cover remover
4.4 Manhole cover remover or J-hook
4.5 Hammer
4.6 Valve exercise hydraulic machine if one is available
4.7 Metal detector / ground probe
4.8 Flashlight
4.9 Hand pump
4.10 Traffic cones
4.11 Traffic work in progress signs
4.12 Stop / Slow signs
4.13 NSA Annapolis USNA Valve Exercise Plan Report
4.14 Accident Prevention Plan if available
4.15 Fifty (60) copies of valve exercise form (Appendix E)
4.16 Valve Exercise Daily Schedule Maps (Appendix D)
4.17 Valve Inventory Table (Appendix A) or Valve Report Forms (Appendix B)
5. Traffic Control
5.1 Before the start of the valve exercise, place traffic cones to block vehicles from parking over valves that will be exercised the following day.
5.2 On the day of the valve exercise, position traffic signs in accordance with base traffic control procedures
5.3 Make sure to have the Accident Prevention Plan on hand
6. Exercise In-service Valves
6.1 Locate the next valve to be exercised from the schedule map for that day
(Appendix C)
6.2 Check the work area around the valve for hazards
6.3 Establish traffic control around the valve
6.4 Remove the valve cover
6.5 Remove any debris from the housing
6.6 Record initial information on a new valve exercise form (Appendix D)
a. Date
b. Inspector
c. Valve ID
d. Valve Location
e. Status
f. Function
g. Purpose
h. Type
6.7 Place valve key on the nut
6.8 Exercise valve as follow:
a. Assume valve is in the full Open position
b. Begin closing the valve slowly, increasing torque as necessary to achieve movement (without exceeding the pre-determined Maximum Torque). For older valves, follow the procedure outlined in section 3.2 of the report.
c. Count the number of turns necessary to achieve the full close position.
d. Check for any external leakage around the housing
e. Begin opening the valve slowly, increasing torque as necessary to achieve movement (without exceeding the pre-determined Maximum Torque).
f. Count the number of turns necessary to achieve the full open position.
g. Repeat the Close/Open cycle a minimum of three (3) times, or until the number of turns necessary to open or close the valve does not change.
5.9 Record the following entries on the valve exercise form
a. Number of turns to close the valve.
b. Depth from ground level.
c. Size by dividing the number of turns by 3 and finding the closest match
d. Direction of operation
e. Normal state
f. In the comments entry, record number of cycles, and maximum torque applied.
g. Condition
h. Needed Repairs
i. Comments specially for service valves if they isolate any building or system when exercised.
j. Draw sketches of how water lines should be connected to floating valves on the map section of the valve form.
5.10 Replace valve cover.
5.11 Prior to departing, evaluate the location for hazards to people, property, or environment, record findings.
5.12 Mitigate any hazards discovered and initiate the actions necessary to eliminate those hazards.
5.13 Remove traffic cones
5.14 Repeat procedure starting with step 5.1 until all in-service valves are exercised.
7. Inspect Abandoned Valves
7.1 Locate the next abandoned valve to be inspected from the schedule map for that day (Appendix E). Abandoned valves are not part of the scheduled valve exercise and should only be visually inspected.
7.2 Check the work area around the valve for hazards
7.3 Establish traffic control around the valve
7.4 Remove the valve cover
7.5 Remove any debris from the housing
7.6 Visually check for valve leakage
7.7 Replace valve cover
7.8 If not marked as abandoned, mark the valve abandoned.
7.9 Prior to departing, evaluate the location for hazards to people, property, or environment, record findings.
7.10 Mitigate any hazards discovered and initiate the actions necessary to eliminate those hazards.
7.11 Remove traffic cones
7.12 Repeat procedure starting with step 6.1 until all abandoned valves are inspected.
8. Cleanup
8.1 Review valve exercise schedule maps to insure that all valves were inspected or exercised.
8.2 Make sure that all valve covers are placed properly
8.3 Remove all traffic cones
8.4 Remove all traffic signs
9. Documentation
9.1 Review all valve exercise forms to make sure that they are filled properly.
9.2 Check exercised valves forms against the schedule map to make sure that all valves of that day were exercised.
9.3 Submit any valve changes to UEM and the GIS department for distribution system update.
9.4 Scan or file the filled out valve exercise forms.
