Introduction The objective of this manual is to train staff on how to replace a hydrant in a timely and efficient manner while, minimizing disruption in service, and insuring the hydrant replacement meets current standards. Should substandard conditions of the peripheral infrastructure be identified, further renovations will be performed. This manual only applies to the replacement of a hydrant, not hydrant repair.

Procedural Overview The Clearances and Locations Work Group will acquire clearances for all utilities, (Gas, power, water, sewer, phone, cable, etc.) before the excavation begins. The Clearances and Locations Work Group will provide the required location numbers, job numbers, drawings and forms to the Supervisor IV as well as organize the removal of some site obstructions i.e. trees and utility poles. The Clearances and Locations Work Group will notify the railway Roadmasters (CN&CP) in advance of work progress near railroad corridors.

All vehicles must be circle checked and the results logged before use. The Supervisor IV or the Clearances and Locations Work Group representative will mark out the water and sewer lines and meet the other utility representatives at the replacement site. The Supervisor IV ensures the Deep Excavation Notification form is submitted prior to excavation. The Supervisor IV will request that the Sign Shop and/or the labourers install the required traffic control devices. Every effort must be made to notify the public affected by a water outage prior to shutting down a water supply line. Before beginning the Supervisor IV will ensure that any buried utilities have been de-energized, if required. The Supervisor IV will coordinate, select and acquire all required equipment and materials and deploy their crew to the job site.

Before using the equipment the tandem axle truck and excavator/backhoe operators must perform circle checks, log results and ensure that the regular maintenance schedule for that equipment has been adhered to. The tandem truck operator will ensure that the trailers are clean and in proper working order and the emergency water supply trailers are completely filled before storing. The tandem truck operator will haul the emergency water supply, shoring and crew trailers - transporting the emergency water supply trailer first and turning on its heater if required. The tandem axle truck operator will notify Central Dispatch of the emergency water supply trailer’s location.

The Supervisor IV will decide on the hydrant location and size of excavation and discuss with the excavator/backhoe operator the best method for excavating. All staff must wear the required personal protective equipment. Asphalt and/or concrete must be stripped, separated and hauled to a designated reclamation site. Where possible excavate parallel to the hydrant branch. Consider the location of other buried utilities. The labourers must locate and expose (shallow buried) underground utilities by hand. The labourers shall communicate the location of all buried utilities to the excavator/backhoe operator. Support all buried utilities as required by their owner’s specifications. The labourers shall inspect shoring before use. The Supervisor IV will confirm that the shoring is in proper working order and installation is in accordance with regulations. Personnel are kept clear when lifting and lowering shoring and/or materials. The shoring is installed with the assistance of the excavator/backhoe in accordance with manufacturer’s recommendations. Shoring must be placed in excavation in such a manner as not to disturb any buried utilities. Shoring must be expanded to support trench walls and endplates installed if required. The access/egress ladder must be in place while

Version # 1-1-3 1


persons are in the excavation. Labourers shall observe the trench walls for signs of collapse throughout the replacement. If at any time a bottom labourer is in danger the other labourers must immediately summon their exit from the excavation.

The labourers will ensure the tools and crew trailer are clean and in proper working order. The top labourer will assemble and pass all the required tools and materials to the bottom labourer. The labourers will disinfect tools and equipment before use on the hydrant replacement. The hydrant will be replaced according to the Trainee Manual. Replace hydrant branch up to 1m (3ft) beyond the face of curb. If present the hydrant drainpipe must be plugged. The pipe must be thoroughly cleaned. The hydrant gasket must be clean and flexible (warm to insure flexibility if required). Ensure coupler and pipe ends are aligned. Ensure the hydrant stands plumb, the hose nozzles are parallel with the curb and the pumper nozzle is aligned with the hydrant branch. Ensure hydrant breakaway flange is at proper grade. Hydrants should never be used to throttle water flow and shall be operated only in the fully open position. Do not force the hydrant in the opening direction beyond the fully open position. Open hydrants quickly and close very slowly. Ensure the hydrant is shut off completely. Compression hydrants must not be over tightened. A quickie saw is not recommended on asbestos cement pipes, as pipe containing asbestos will create dangerous airborne particles while cutting. A recognized dangerous goods carrier must transport asbestos-cement pipe pieces over 5-kgs. Install Cathodic Protection as per the Trainee Manual. Couplers must be blocked securely.

The top labourer will install the throttle valve and discharge hose for the hydrant flushing, and operate the hydrant. The water line shall be re-energized/filled. The Supervisor IV will perform or monitor the performance of the water line flushing and water quality testing. The bottom labourer will observe the new replacement for leaks. The Supervisor IV will ensure the repair meets all specifications and recommended practices. Backfill all buried utilities as required by their owner’s specifications and confirm backfill specifications have been met. The top labourer will direct the tandem axle truck operator to dump the backfill material. The Supervisor IV ensures backfill material meets the requirements. Soil and granular material must be compacted to a standard proctor density minimum of 98% and be free from frozen or substandard backfill material. Non-shrink backfill must be used beneath concrete or paving stone sidewalks or driveways. Pavement cut will be left down if instructed by the Asphalt Supervisor. Final grade of all excavations must be smooth and level.

Driveways, road surfaces and sidewalks must be swept clean. The Supervisor IV will inspect the site for cleanliness before leaving the site. All unnecessary traffic control devices will be removed from the roadway prior to leaving the site. The Supervisor IV will submit a plan of the closed valves to the Valve Supervisor. The Supervisor IV will ensure that all the required forms and documentation are complete and submitted - at the end of the day the job is completed. The Clearances and Locations Work Group will update the manual and electronic records.

Version # 1-1-3 9


Every effort will be made to notify the public affected by a water outage. Emergency water supply trailers and temporary hook ups are options to consider when there is a water outage. A generic notification letter may be posted on apartments (front and rear doors) where notifying all individuals affected is not possible.

Notes:

Figure 13 - Emergency Water Supply Trailer

Every effort should be made to cut the asphalt or concrete with an earth saw (winter), quickie saw or asphalt saw (summer) prior to excavating.

Notes:

Figure 14 - Asphalt Saw

Version # 1-1-3 10


Asphalt or concrete will be stripped, separated and hauled away to the designated reclamation site. Asphalt and concrete can be recycled.

Notes:

Figure 15 - Recycling

Once the various conditions are evaluated, the dimensions of the excavation will determine the type of shoring selected. When excavating to repair a hydrant, ensure that the majority of the excavation is on the opposite side of the sewer main, - if possible.

Notes:

Figure 16 - Excavator/backhoe

Version # 1-1-3 11


If the hydrant being replaced is in an industrial, commercial or school area or on any water main equal to or greater than 300mm (12inches), it shall have a valve installed on its lead.

Notes:

Hydrant Lead Valve

The trench will be sorted into salvageable material (wet or dry) and non-salvageable material. If stockpiling of salvageable material on site is not a viable option, a dumpsite will be used. The toe of the spoil pile must be a minimum of 1m (3feet 4inches) from the edge of the excavation.

Notes:

Figure 18 - Spoil Pile

Version # 1-1-3 12


When locating a buried utility deeper than 1.2meters (4feet), shoring must be placed in excavation prior to worker probing for the utility.

Notes:

General Excavation Safety

In the event that a natural gas line is hit, the machine must be immediately turned off as the engine may ignite the gas (especially in calm conditions).

Notes:

Figure 21 - Excavator/Backhoe That Struck A Gas Line.

If the vehicle contacts overhead power lines do not exit the vehicle until told it is safe to do so by qualified personnel.

Notes:

Figure 22 - Truck Contacting Overhead Power Lines

Version # 1-1-3 14


Do not go in-between the excavator bucket and the truck being loaded. Do not stand under the bucket of the excavator/backhoe. Keep clear of the swing of the turntable and reach of the excavator/backhoe.

Notes: Danger Zone

Figure 23 - Danger Zone

No worker shall enter an excavation deeper then 1.2m (4feet), without the installation of a temporary protective structure.

Notes:

Figure 24 - Trench Cave-in

Version # 1-1-3 15


Preparing for Repair

Make sure shoring and trailer, are clean and in proper working order for transporting. Shoring trailers shall not be used to transport material unless designated for such use. Park trailer where there are no overhead lines or tree branches. Check for cracks on the shoring eyebolts and chains. Ensure that tie down straps are in good condition (Not frayed or torn).

Notes:

Figure 25 - Shoring on Trailer

Hook up chain appropriately so as not to crowd lift or flexibility. Keep the chain short when transporting the shoring from the trailer to the excavation, this prevents the shoring from swinging excessively.

Notes:

Figure 26 - Shoring Installation.

Version # 1-1-3 16


Position the excavator/backhoe far enough back so the shoring can be lifted and lowered safely. Use tag lines wherever possible. Naturally frozen soil is not considered safe and therefore must be shored.

Notes:

Figure 27 - Shoring Lowered into Excavation

Once the shoring is in the excavation the side panels must be expanded hydraulically to be tight against the excavation walls. Endplates must be installed if the ends of the excavation are not sloped.

Notes:

Figure 28 – Shoring with Endplates

Version # 1-1-3 17


All tools must be disinfected prior to use on a water main, especially if they have been previously used on a sewer repair. Ensure that the proper disinfectant applicator is used.

Notes:

Figure 29 - Disinfectant Applicator

Clean off excess dirt with a rag and wire brush prior to soaking with disinfectant. Soak items with disinfectant solution (Min 5% Sodium Hypo-chlorite solution), let soak for a minimum of 7 seconds. Scrub item with a clean rag then rinse clean with disinfectant solution. Let tools dry before use.

Notes:

Figure 30 - Disinfecting

Version # 1-1-3 18


After excavation is completed and portable shoring is in place, place ladder in hole, securing it inside the shoring. The bottom labourer now proceeds to enter excavation. Make sure bottom labourer is wearing all personal protective equipment.

Notes:

Figure 70 – Cadweld Complete

Version # 1-1-3 38


Apply a tar patch or mastic equivalent over weld. Sacrificial anode is now installed

Notes:

Figure 71 - Denso Tape Patch

In order for the anode to work, the cardboard packaging must be wet. Depending on the ground conditions, it can take several months to a year before a dry anode will soak up enough groundwater to work efficiently. In order to allow the anodes to function sooner, it is standard practice to soak the anodes with water before backfilling.

Notes:

Figure 72 - Anode Cardboard Packing

Version # 1-1-3 39


Post Repair

Remove all hand tools from excavation, exit, and remove ladder.

Notes:

Figure 73 - Labourer Exiting Excavation

Disinfect throttle valve and hydrant port with sodium hypochlorite water solution. Make sure the throttle valve is open, and put the hose into storm, sanitary manhole or catch basin.

Notes:

Figure 69 - Disinfect Throttle Valve

Version # 1-1-3 40


Attach throttle valve to hydrant along with a hose.

Notes:

Figure 74 - Throttle Valve & Hose

To open hydrant turn the operating nut clock wise until hydrant is completely open. Depending on the make of hydrant, anywhere from 13 to 30 turns may be required to open a hydrant completely.

Notes:

Operating Nut

Figure 75 – Operating Nut

Version # 1-1-3 41


Open the valve furthest from hydrant you are using. Air will be expelled from the water line while it fills with water. Open the valve slowly, opening it too fast will create water hammer, which can damage to the water main.

Notes:

Figure 76 - Hydrant Flushing

When the air has been flushed from the system begin testing the water. Take a water sample from the hydrant with the water sample jar. Test for turbidity and chlorine. Deliver water sample to the water treatment plant. Follow the procedures in the water quality SOP.

Notes:

Figure 77 - Water Testing

Version # 1-1-3 42


Close the hydrant at a rate no faster than 1 revolution every 3 seconds. Closing a hydrant too quickly can create water hammer sufficient to rupture the water main.

Notes:

Figure 78 - Closing Hydrant

Compression hydrants do not require excessive force to close. Closing them too tightly will deform and damage the disk rubber (valve) at the bottom of the hydrant, resulting in leakage and eventual replacement.

Notes:

Figure 79 - Compression Hydrant Schematic

Ensure hydrant is closed by listening for the sound of pressurized water with a hydrophone or by placing your ear against the hydrant. If there is any sound tighten the hydrant slightly and recheck for sound. Be sure the sound is that of pressurized water and not the sound of water draining from the hydrant , which is normal.

Notes:

Figure 80 - Listening to Hydrant

Version # 1-1-3 43


If you are confidant the hydrant is not closing down properly, flush the hydrant - as there may be something wedged underneath the disk rubber allowing the water to flow by.

Notes:

Figure 81 - Hydrant Flushing

When the water flow has stopped, loosen off the operating nut slightly to remove the stress from the operating parts. You should be able to move the operating nut by hand, if it is a compression hydrant. This will ensure the hydrant operates easily when required.

Notes:

Operating Nut

Figure 82 - Operating Nut

Version # 1-1-3 44


After closing the hydrant, check for proper drainage from the barrel. Drainage should be sufficient to create suction when a hand is held over a port.

Notes:

Hydrant Barrel

Figure 83 - Hydrant Barrel

Replace the Port caps but leave them loose enough to allow air to pass by so the hydrant may continue to drain.

Notes:

Figure 84 - Port Cap

Version # 1-1-3 45


Once the hydrant has drained completely, tighten the port caps with a hydrant wrench (never a pipe wrench), and then back them off slightly so they will not be excessively tight but tight enough that they cannot be removed by hand.

Notes:

Figure 85 - Hydrant Key or Wrench

The water main is now under pressure. Check the new repair for leaks. Listen to the hydrant for sounds that could indicate a break in the main.

Notes:

Figure 86 - Looking For Leaks

Version # 1-1-3 46


Excavator/Backhoe operator removes shoring from excavation, placing it on its trailer. Ensure all shoring equipment and trailer have been serviced and are ready for the next job. Keep shoring clean. Keep shoring trailer clean of rocks and debris. End plates should be stored in proper place on trailer and be easily accessible.

Notes:

Figure 87 – Remove Shoring
