• Fire hydrants without auxiliary valves

• Broken valves that need to be replaced

• Sections of your system that can not be isolated

• Old water main that needs to be replaced

• Repairs that require system shutdown

to complete

System O&M Challenges…

Page 3: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

• A shut-off valve is

broken or, worse

yet, does not

exist?

The Problem…

• A hydrant repair

becomes hydrant

replacement?

Page 4: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

Turn off the water supply and suffer the consequences later!!!

Old Technique…

Page 5: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

• System pressure drops

• Large portion of the community without water

• Possibility of boil orders due to contamination

• Loss of fire protection

• Loss of water revenue

• Possible EPA involvement

Eliminate Health & Safety Risk with a Line Stop or Valve Insertion

Impacts & Challenges of Shut Down…

Community Impact

Page 6: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

– Difficulty locating underground or under-

pavement valves

– Determining whether all valves work

– Unsafe working environment

– Purge Air and Flushing

– Overtime / Comp time issues

– Cleaning plugged meters

Eliminate Health & Safety Risk with a Line Stop or Valve Insertion

Impacts & Challenges of Shut Down…

Work Challenges

Page 7: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

• Larger pipe sizes, greater water

pressure and greater volume of water

• More demands on your time, smaller

staffing

• Age of pipe, valves, and hydrants

• Attitudes of society have changed –

impatient. Social media “blitz”.

Why Change Now?

Page 8: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

• New regulations – more stringent

water quality standards

• Regulation enforcement

• Water conservation

• Operator safety

• Budget Considerations

Why Change Now?

Page 9: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

Project Constants:

➢ Excavation

➢ Material (valve, hydrant,

etc.) labor,

Inherent to any process, no

matter how you handle

your shutdown problem.

The True Cost to Shut Down…

Page 10: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

➢ Time to read the maps…if

they are correct

➢ Locate and turn valves

➢Break a valve

➢ Advertise the shutdown

➢ Overtime

➢ Loss of fire protection

➢ Increased liability

➢ Backflow problems

The True Cost to Shut Down…

Page 11: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

➢ Compliance with rules and regulations

➢Issuing of boil orders

➢Sampling

➢Lab costs

➢Additional notification

➢Media fallout

➢Re-chlorinization and de-chlorinization

➢ Loss of treated water

➢Gallons lost draining

➢Gallons lost purging➢ Loss of water revenue

The True Cost to Shut Down…

Page 12: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

Line Stopping

Never shutdown…

Page 13: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

Use a line-stop/insert valve system…instead of

shutting down

Page 14: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

Required – Line tapping machine (typical below)

Page 15: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

Side Tapping (illustrated)

Page 16: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

• Establishes a connection

to an existing pipeline

• Utilizes a valve, fitting,

and sealed tapping

machine to cut a hole

into pipeline without loss

of pressure or contents

• Available sizes: 4″

through 20″

• Also known as hot

tapping

Line Tapping Explained…

Page 17: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

Traditional Tapping Methods

Traditional tapping methods provides a means for

coupon retention which allows for inspection,

evaluation and verification.

Line Stopping Machine (illustrated)

Page 19: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

• Developed over 50 years

ago; introduced to water

industry in 1980

• Utilizes the line tapping

process with the addition

of flow stopping

• Temporarily stops flow to

allow repairs or

maintenance without

disrupting service

– Gas distribution systems

– Industrial systems

• Used by 1000’s of

municipalities: Domestic and

International

Line Stopping

Page 22: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

➢ Commonly used when:

➢ Inserting, changing or

repairing valves

➢ Adding, changing or

repairing hydrants

➢ Tying in new lines or

services

➢ Performing repairs

➢ Changing large meters or

backflow preventers

➢ Abandoning, cutting or

capping lines

AWWA Standards➢ There are no AWWA standards covering

insertion valves.

➢ AWWA C509-15 (Resilient-Seated Gate Valves

for Water Supply Service) is the closest

standard which applies to insertion valves.

➢ Some material specifications of C509-15 are

met depending on the manufacturer.

➢ The important part of C509-15 are the

performance standards or the “Proof of Design”

tests.

Page 71: Distribution Maintenance & Repair Techniques to Avoid ......• System Shutdown –Boil orders –Complicated planning –Loss of fire protection –Large street excavation and street

➢C509-15 Proof of design consists of 4

separate tests.
