Black Fibre (Orangeburg) Pipe

12

Beginnings (con’t)

City Waterloo goal was to reduce cost and minimize disruption on residential properties

UW investigated different construction methods (open cut $6500 per lateral)

Pipe bursting identified as replacement method ($4500-4000 per lateral)

Estimated savings to City of Waterloo approx $4 million

13

Beginnings

1994 CATT started at the University of WaterlooInitial membership

National Research Council (NRC)City of WaterlooUniversity of WaterlooTRS pipe bursting 25 founding members:

Municipalities, Consultants, Contractors, Manufacturers.

1996 CATT identified as an official UW research centre2002 Senate extended Centre for another five years

14

CATT’S Mandate

To serve its members and the public by addressing CRITICAL ISSUESfacing underground infrastructure installation, assessment, repair,

renewal, and management.


8

15

Vision Statement

To help municipalities and industry solve and manage their underground

infrastructure problems through research, education, technology transfer, and training of highly

qualified personnel.

What a pothole! KITCHENER, ON (Mar 15, 2005)

Kitchener city employees repair a water main break that caused athree-metre-deep sinkhole that swallowed the Rhoades family van on Plymouth Road Sunday. Richard Rhoades, 7, broke his jaw when thefamily van hit a sinkhole.

Sinkhole from water main break causes havoc in neighbourhood

Operation/Maintenance Costs

Operation cost are exceeding revenuesmany municipal systems are operated so

that revenue = operation.Low water costs

Mandated government fiscal accountabilityIn New Zealand and Australia government

put policy in place that Water and Sewer must be operated on a full cost recovery bases

Bottled Water33 billion Can. dollar industry

Canadians bought more than 700 million litresof bottled water last year. We spent about half a billion dollars on it. In a country with lots of fresh, free water, what we pay for it by the bottle is astonishing.

CBC MARKETPLACE:

Is bottled water safer than tap water?Broadcast: Feb 8, 2000

Canadians have taken to bottled water like -- fish to water

The SIX Main Questions1. What do we own?2. How old is it?3. Where is it?4. What condition is it in?5. How is it performing?

Can we extend the pipe plant life Does it need to be replaced

6. How do we manage the system?
