Day 2: 10 am to 1:30 pm Eastern

After participating in this course, you will be able to:

  • Inspect and evaluate water main systems
  • Recognize the importance of water distribution system rehabilitation
  • Compare the benefits and limitations of various methods used in the rehabilitation of water mains
  • Develop key performance indicators for water mains
  • Choose the appropriate asset data to collect

Since potable water is an essential service, the infrastructure it is conveyed in is regularly inspected, maintained and rehabilitated. Since the methods used for water main rehabilitation are constantly evolving, engineers and technologists must understand the benefits and limitations of each method in order to make an informed decision on which method is best for a particular situation.

The ASCE has determined that over 6 billion gallons of treated water are lost every day in the United States. There has been no quantification in Canada, but it is not uncommon to read or hear of water main failures ranging from domestic services to large-diameter transmission mains.
